Analog Capacitive Soil Moisture Sensor V1.2 GSM/GPS/GPRS Feature ESP32-WROOM-32 ESP32-WROOM-32D ESP32-WROOM-32U CPUAnalog Capacitive Soil Moisture Sensor V1. 2 Analog Capacitive Soil Moisture Sensor (Anti Corrosion) is a soil moisture sensor based on capacitance variation. Compared with the resistive sensor, the capacitive sensor does not require direct contact with the metal electrode, which can greatly reduce the electrode corrosion, it is considered to be anti corrosion. It is important to note that this sensor can only qualitatively test soil moisture and
