Arduino monitor water level with NodeMCU ESP8266
This project will check water level in tank if water level < 20% pump will start and when water level > 80% pump will stop with HC-SR04 ultrasonic sensor, show data in 0.96 inch OLED Display and send distance to firebase realtime database for React dash board in next project.
