This V2.0 capacitive soil moisture sensor measures soil moisture through a capacitive sensor, not a resistive sensor like other sensors on the market. It is made of anti-corrosion material, providing excellent service life. Attach it to the soil around your plants and impress your friends with real-time soil moisture data!
This module includes an integrated voltage regulator providing it with an operating voltage range of 3.3 ~ 5.5V. It is perfect for low voltage microcontrollers, both 3.3V and 5V. For compatibility with Raspberry Pi, an ADC adapter is required.
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 cannot measure it quantitatively. As soil moisture increases, yield values decrease; conversely, when the humidity decreases, the output value becomes higher.
