Receiving Distance & Duration from UltrasonicSensor & Nodemcu ESP8266
This is data showing water volume for a reservoir. Reservoir devices are off the grid (no power, wifi) and use an AVR Iot Cellular Mini with JSN-SR04T sensors using cellular to post data. Variations use LiPo bat or capacitor plus solar panel for power.
in this IOT project, Ultrasonic sensor is used to detect the fuel level in bike petrol tank and also using ESP8266 to upload that data in thinkspeak.
