This is a simple humidity sensor, which can be used to measure the humidity in the ground. This makes it possible for the Arduino to give a notification if the plant needs water. This module has both the possibility of digital and analog output, whereby the digital output threshold can be set by means of a potentiometer.The module also ordered 2 indication LEDs, Power (red), Digital output high (green).Interface (4-pin): * VCC: .3V - 5V * GND: GND * DO: digital output (0 or 1) * AO: Analog output Contains: * Sensor module * Probe * 2-core cable https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2025-01-22 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2025-04-20 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2025-05-18 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2025-05-19 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2025-06-24 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2025-06-25 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2026-02-23 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2026-02-27 https://elecena.pl/product/27738313/opencircuit-ground-humidity-sensor-module 2026-04-14
