The YL-69 Soil Moisture Sensor Module is designed to measure the moisture content in soil. It is commonly used in agriculture, gardening, and automated irrigation systems to monitor soil moisture levels and control the watering of plants based on soil conditions.
This sensor module employs a resistive sensing technique to measure soil moisture. It consists of two electrodes or probes that are inserted into the soil. When the soil moisture level changes, the electrical resistance between the probes also changes. The module converts this resistance into an analog voltage signal, which can be read by a microcontroller or analog-to-digital converter (ADC).Specificatoins of YL-69 Soil Moisture Detection Sensor Module:
