ESP32 water level monitoring system
This project is constructed uses ESP32 with HC-SR04 ultrasonic sensor and water sensor to detect the position of water in the water storage tank. If the water level is lower than the set water level limit, use relay to start the pumping motor to pump water into the water storage tank. When the water sensor senses the water level stops pumping, and the value is sent to the MQTT server and displayed through the Node-red dashboard.
ESP32 code is placed on my blog :
