Abstract: coronavirus outbreak pandemic by COVID-19 social distancing in the population has been a major prevention practice, compelled by all government agencies worldwide. Despite strong recommendations to maintain at least one-and-a-half-meter distance between the persons, the guideline is not scrupulously followed. To overcome this situation, an IoT-based technical solution is proposed through this paper. PIR sensor is used for the detection of a target in the vicinity (1.5 m). Upon violation of social distancing norms, the system will trigger an audio alarm after the detection of the target object measures to reduce the spread of COVID-19. But these approaches are applicable in a mass population. At the same time, it is a responsibility of an individual to follow the interim guidelines issued by the WHO to maintain social distancing of 2 m. For the same, there is no such technical mechanism. Due to this, there is a need for such a device that will find the presence of human beings in the vicinity and alerts individually about the same so that he/she will maintain a social distancing. Due to this, the spread of the COVID-19 virus will minimize. In the suggested proposed device, PIR sensor interfaced with Arduino which will detect the human presence. If human presence will be there, then it will notify the individual through the audio message. Hence, the individual will be alerted and will maintain the social distancing at the public place also. By wearing this device, any person will come to know the presence of a human being nearby him/her. Due to that, it will be helpful to keep social distancing to avoid the spread of the COVID-19 virus. By using this device, the user will be alerted in case of violation of the interim guideline issued by the WHO to maintain the social distancing. This will minimize the spread of the virus in the community or in the people who are infected or were in contact with infected persons or COVID-19-affected persons.

Abstract: This project is taken up as India is an agriculture oriented country and the rate at which water resources are depleting is a dangerous threat hence there is a need of smart and efficient way of irrigation. In this project we have implemented sensors which detect the humidity in the soil (agricultural field) and supply water to the field which has water requirement. The project is PIC16F877A microcontroller based design which controls the water supply and the field to be irrigated. There are sensors present in each field which are not activated till water is present on the field. Once the field gets dry sensors sense the requirement of water in the field and send a signal to the microcontroller. Microcontroller then supply water to that particular field which has water requirement till the sensors is deactivated again. In case, when there are more than one signal for water requirement then the microcontroller will prioritize the first received signal and irrigate the fields accordingly. This project uses PIC16F877A Microcontroller. It is programmed in such a way that it will sense the moisture level of the plants and supply the water if required. This type of system is often used for general plant care, as part of caring for small and large gardens. Normally, the plants need to be watered twice daily, morning and evening. So, the microcontroller has to be coded to water the plants in the greenhouse about two times per day. People enjoy plants, their benefits and the feeling related to nurturing them. However for most people it becomes challenging to keep them healthy and alive. To solve this problem we made a project for those who cannot water the plant due to their busy schedule or when they go outside for long time. The system automation is designed to be assistive to the user. We hope that through this project people will enjoy having plants without the challenges related to absent or forgetfulness.

Abstract: Abstract Now a day’s water is becoming very precious due to scarcity in obtaining clean water for domestic purpose including irrigation. In order to optimize the use of water, mechanism to develop water conversation is the need of the hour. Also, automation in agricultural systems is a necessity to optimize water usage, reduce water wastage, and to implement modern technology in agriculture systems. Soil moisture sensor is a novel device which senses the moisture content in the soil, and with suitable mechanism allows water to be irrigated depending on the moisture content of the soil. This allows flow of water or stoppage of water to the plants by using an automated irrigation system. The device consists of an Arduino board, which is the micro controller which activates the water pump and supplies water to plants through Rotating Platform Sprinkler. A submersible motor pump is used for this purpose of pumping water. This system uses low power consumption and pumps water up to 100 litres/hour. Necessary tunings for pumping and supplying water is arranged depending on the consumption of water. This involves a power supply of 2.5 V to 6 V. Soil moisture sensor is inserted in the soil which contains a probe to measure the moisture content of the soil.

Abstract: The configuration of the sensor input is made via the multi-function input. Resistance thermometers, thermocouples and standard industrial signals, such as 4 ... 20 mA, serve as the input variable of a temperature controller. The monitoring output can be set either as relay (for slow control), as logic level for the control of electronic solid-state relays (for fast control and high current loads) or as a continuous 4 ... 20 mA output.The project is intended to provide proper amount of irrigation to agricultural fields by observing the moisture content of soil. The project automates the process of manually irrigating the fields by switching the pump ON/OFF. It is implemented by using an 8051 series microcontroller, programmed such as to collect input signals that measures moisture content of soil through sensing arrangement. Sensing arrangement is made by inserting two stiff metallic rods into the field at some distance. An op-amp is used as a comparator that interfaces microcontroller and the sensing arrangement. On receiving the signal, the microcontroller produces an output that drives a relay and operates the water pump. Also LCD is used which is interfaced with microcontroller for displaying the moisture content of soil and water pump status. Hence the system reduces human intervention and provides required irrigation to field.

Abstract: Opening and closing of doors have always been a tedious and boring job, especially in places like; hotels, shopping malls, theaters, etc where a person is always required to open and close the door for visitors. This human involvement can be avoided by automating the gate. The system combines ultrasonic sensor, servo, and Arduino to achieve the desired goal. When the ultrasonic sensor installed at the entrance of the building detects a person or an object within the range of the sensor, a signal is sent to the Arduino microcontroller which controls the servo motor to automatically open the door. The door remains open until the object goes out of range of the sensor and in turn closes the door automatically. The results clearly show that the system is cheap, effective, and a reliable means of opening and closing doors places like retail stores, super markets, factories and the like.

This system is a design, which makes this self-sufficient, watering itself from a reservoir. Various pests can be detected automatically through the sensor so that we can avoid the crucial loss of livestock. In order to safeguard the field crops from the pests, the PIR sensor is used to detect the pests over a range. when the creature gets close enough to the PIR sensor, then the change in the IR energy might be just enough to trigger it. This technology is very promising for the early detection and monitoring of the agricultural fields.

Hardware: smoke detector,arduino,led lights,resistor,pizzo buzzer

Abstract: Automatic Smoke Alarm Detector, In case of fire a home/office the internal parts of the premises gets filled with smoke. This smoke layer progressively becomes so thick that it lowers the visibility considerably. We can use this fact to constructor simple smoke detector alarm that can notify the residents in around the premises about the fire breakout. The Automatic Smoke Detector Alarm is very compactas it doesn’t employs the costly smoke detecting sensors.It has pair of infrared sensors which are continuously monitoring the visibility in the premises where they are attached. Incaseafireerupts, smoke gets generated and spreads in and around the premises. Once this smoke reaches the smoke detector module the visibility of the infraredsensors get obstructed.This triggers a fire alarm in the detector module.Hearing this alarm the resident in and around the premisescanget alert about the fire and vacate the premises. The alarm goes ringing till there is smoke in the premises and goes off. once the smoke recedes.The principle behind working of the is project is of the opaqueness property of smoke. In case when there is no smoke the infrared sensors are continuously in view of each other. Once smoke comes in the view, the sensor signals obstructed and the output of the sensor changes.This change is sensed by the system to ring an alarm to notify the residents in and around the premises about the fire breakout.

Abstract: Piles of garbage are one of the major problems faced by most people in our country. Many times, in our city we see that the dumpsters placed in public places are overloaded. It creates unhygienic conditions for people as well as ugliness in that place leaving a bad smell and also leading to sanitary issues and disease. To avoid all such situations we are going to implement a project called “THE DUMP GAFFER USING IOT”. The proposed system consists of an ultrasonic sensor to measure the waste level, an ESP32 module that Controls the system operations, and an LCD 16x2 display to indicate the level of garbage in the dumpster. The update of the level of garbage pile is shown both on the LCD display and on the IoT platform which is connected to it, where here it is on Blynk IoT. It can also be able to generate a warning message to the municipality via Blynk IoT (or any cloud platform similar to it for more security) when the garbage bin is full or almost full, so the garbage can be collected immediately. The main aim of this project is to reduce human resources and efforts along with the enhancement of a smart city vision. Furthermore, it is expected to contribute to improving the efficiency of solid waste disposal management.

Abstract: Traffic congestion causes many problems, and deaths occur as a result of delays in emergency vehicles reaching their destinations. Therefore, our top priorities are to reduce traffic in society and create space for emergency vehicles to move through traffic freely. The project comprises of two phases. Phase one is the command for 4-way directional control, and in phase two, is the program for emergency situation control. The traffic lights are altered to only turn ON at that precise moment, up until or unless the frequency of emergency vehicles coincides with the sensor's operating range. The sensor in this instance is positioned at a specific distance to optimize the density and frequency of traffic flow in order to maintain an effective traffic signal control system at a specific intersection. The traffic lights continue to handle their standard delay function once none of the sensors have detected a sign.
