ESP32 Water Level Monitoring Using ESP-NOW and Float Sensors

ESP32 Water Level Monitoring in storage tanks is an important task in homes, industries, and agriculture. In this project, we build a wireless water level monitoring system using two ESP32 boards, float sensors, and the fast wireless communication protocol ESP-NOW.The system sends water level data from one ESP32 to another without using a router or internet connection. The receiver ESP32 displays the water level status on the Serial Monitor, making the system simple, efficient, and reliable.IntroductionWater tanks often require manual...
