From the project

ESP-NOW based solar-powered water level monitoring system for overhead tanks. An outdoor ESP8266 node uses a waterproof ultrasonic sensor to measure water level and transmits data wirelessly without internet. Designed for ultra-low power, outdoor reliability, and real-world deployment.

The TWIN-NODE Motor Controller is a compact wireless motor control module designed to work with the TWIN-NODE water level monitoring system. It enables remote ON/OFF control of a water pump using ESP-NOW, without internet connectivity.
