DESCRIPTION
The package includes 5 capacitive soil moisture sensors.
SPECIFICATION
- It is made of a corrosion resistant material, which gives it a long lifespan
- Applications: moisture detection, smart garden, smart irrigation
- Operating voltage range of 3.3 ~ 5.5
- Capacitive Soil Moisture Sensor for Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V or 3.3V microcontroller.
- Tutorials for Arduino, ESP32, ESP8266, Raspberry Pi, Raspberry Pi, and MicroPython are provided
※ NOTE THAT:
- If you are using the ESP32, you need to configure the ADC with 11 dB attenuation to set the voltage reference range to handle up to 3.3V.
- Don't use pure water for testing because it doesn't conduct electricity, so it won't change the sensor readings.
- The reading value range from micro-controller depends on the following factors:
- How deep the sensor is placed
- The composition of soil or water
- The voltage suppplies to the VCC pin.
- Voltage reference of ADC.
- ADC resolution of micro-controller.
- Avoid burying the circuit part (found on top of the sensor) in soil or water, as it could harm the sensor.
