FireBeetle Detects Water Using ESP32 Sensor Project

A maker blog publishes a DIY water-sensing IoT project that uses the DFRobot FireBeetle 2 ESP32-E and Crowtail Water Sensor to detect water via exposed trace shorting. The build includes a 3.5" 480×320 capacitive TFT display, 1000mAh battery, IO shield, and example schematics, code, and links to DFRobot and video tutorials. Builders can prototype battery-powered leak or level monitors quickly.
