A Smart Bin Implementation Using LoRa

DOWNLOAD ABSTRACT

AIM:

Design and Development of a Smart Bin Implementation using LoRa.

PURPOSE:

Metro cities should maintain clean atmosphere around the city. Irregular maintenance of garbage creates diseases spreading and creates unhealthy conditions. To overcome this kind of solution we come up with solution of smart bin implementation. It has additional features like smoke level reading, Temperature and humidity reading.  Here Bin has ultrasonic level sensor that can find level of bin and update to LoRa gateway. LoRa gate way is in fixed location like command control center (CCC), where data will be uploading to IOT cloud server. Detecting of smoke level, temperature and humidity through this gives additional advantage to users to predict atmospheric conditions. The final proposed project title is Smart bin implementation using LoRa technology.           

DESCRIPTION:

Arduino interfaced with LoRa module through SPI communication. Ultrasonic sensor, DHT11 and Mq2 sensors connected to Arduino digital and analog pins respectively. ESP32 nodemcu interfaced with LoRa module SPI port.

WORKING:

Arduino reads sensors information and displaying on LCD. Here ultrasonic sensor placed on top of the bin and it can read level of bin and also DHT11, Mq2 sensors placed at top of the bin. These sensors read temperature, humidity and smoke levels of surroundings. All this data transmit to LoRa receiver. LoRa receiver is like LoRa gateway and it has ESP32 nodemcu. Nodemcu has inbuilt WIFI and this will update all sensors data to IOT cloud server. Municipal authorities can send cleaning vehicle to particular bin based on this information. Also, people we want to throw their waste into bin can see information of local bins and do their work. Additional information like temperature, humidity and smoke level information will be useful for weather monitoring department. Finally this project helps in various aspects.
