DIYables Capacitive Soil Moisture Sensor Module for Arduino, ESP32, ESP8266, Raspberry Pi, 5 pieces

Key Features

• 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
• 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.
