Soil moisture sensor for measuring the volumetric content of water in the soil. The sensor uses as a probe. To use the sensor, plug it into the ground and connect it to an analog input of a microcontroller. The more soil hydrated, the higher the output signal of the sensor. With this sensor, you can make an automatic watering device to prevent your plants from withering due to a lack of water when you are not at home for a long time or have passed the watering time. This sensors can let your plants grow more comfortably and make your garden become more intelligent. The surface has gone through plating processing to enhance the electrical conductivity and corrosion resistance. Easy to install
Characteristics list Soil Moisture Sensor
- Output signal: Analog
- Power: 3.3-5V
- Operating Current: less than 20mA
- Output voltage: 0-2.3V (2.3V is completely immersed in water voltage value)
- 5V power supply, the greater the humidity, the greater the output voltage.
