Analog Capacitive Soil Moisture Sensor 220V 4000W SCR Voltage Regulator License-Free Frequency: 433MHz ISM bandAnalog Capacitive Soil Moisture Sensor Accurately measure soil moisture levels without corrosion issues this capacitive soil moisture sensor uses a change in capacitance rather than resistivity, dramatically extending sensor lifespan. Outputs a simple analog voltage signal that varies with soil moisture content, making it ideal for automated plant watering systems, smart agriculture projects, and environmental monitoring.
