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

Key Features

• Corrosion-Resistant Design — Capacitive sensing provides longer lifespan than resistive sensors
• Analog Output — Provides continuous moisture level readings
• Wide Voltage Range — Operating voltage 3.3V to 5.5V for broad microcontroller compatibility
• 5-Pack — Includes five sensors for multi-plant or multi-zone monitoring
• Smart Agriculture Applications — Ideal for smart garden, automatic irrigation, and moisture detection projects
• Presoldered and Not Soldered Options — Provided in presoldered and not soldered versions for selection
• Tutorial Support — Comprehensive tutorials and MicroPython support available
• ...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.
