Using UltraSonic Sensor

Obstacle detection for blind people This channel stores real-time distance readings from an ultrasonic sensor used for detecting obstacles. Data is sent via NodeMCU to ThingSpeak.

distance measurement using(esp8266, ultrasonic sensor)

i am using ultra Sonic sensor to calculate the distance .

ESP32 Smart Dustbin data (Distance, Fill %, Status)

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.

Rainwater tank monitor with battery powered ESP32 and ultrasonic sensor

Water Level in Sump

To calculate the distance via ultrasonic

Channel that contains all the data gathered by FRED.

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.
