Perfect for educational uses, the Adafruit Simple Soil Moisture Sensor is low cost, and easy to use. This is a simple resistive style moisture sensor, where there's two prongs and the sensor measures the conductivity between the two. We gold-plated the prongs so reduce risk of oxidation - if you see build-up on the prongs, clean them off with a dish-scrubber to keep the sensor going. https://elecena.pl/product/29047218/adafruit-simple-soil-moisture-sensor-for-micro-bit-and-more 2025-07-03 https://elecena.pl/product/29047218/adafruit-simple-soil-moisture-sensor-for-micro-bit-and-more 2025-09-30
