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.
Key Points
- 1Uses DFRobot FireBeetle 2 ESP32-E, Crowtail Water Sensor, and 3.5″ capacitive display.
- 2Provides simple water-detection via 1 MΩ pull-up traces, enabling digital I/O short detection.
- 3Enables practitioners to prototype battery-powered IoT leak/level monitors with provided schematics and code.
Scoring Rationale
Provides practical, directly usable prototype resources, but limited novelty and niche maker audience reduces broader impact.
