5PCS Capacitive Analog Soil Moisture Sensor Module 3.3~5.5V Corrosion Resistant Humidity Detection Sensors DIY Electronic for Arduino for Raspberry Pi
- 【Version】This capacitive analog soil moisture sensor is V1.2
- 【Voltage】Working voltage: 3.3~5.5 VDC, output voltage: 0~3.0 VDC
- 【Interface】Interface: PH2.54-3P, Pin: Analog signal output, GND, VCC
- 【Feature】Capacitive humidity sensor has good linearity, good repeatability, small hysteresis, fast response, small size, and can be used at - 10 °C - 60 °C humidity environment
- 【Comparision】This capacitive soil humidity sensor is different from most of the resistive sensors. It uses the capacitive sensing principle to detect soil humidity, avoiding the problem that the resistive sensor is easily corroded, and greatly extending its working life.

The sensor has a built-in regulator chip, which supports a wide voltage working environment of 3.3~5.5V, which means that it can work normally even on the 3.3V Arduino main control board.
The iconic DFRobot-Gravity interface ensures the compatibility of the interface and can be directly connected to the Gavity IO expansion board.
Micro PCs such as raspberry pie can work only by connecting an ADC (analog signal to digital signal) conversion module.
Specifications
Operating Voltage: DC 3.3-5.5V
Output Voltage: DC 0-3.0V
Interface: PH2.0-3P
Size: 99mmx16mm/3.9"x0.63"
Supports 3-Pin Gravity Sensor interface
Analog output
Applications:
Garden plants
Moisture detection
Intelligent agriculture
Horticulture
Environmental monitoring
It can be used to monitor soil moisture levels in real-time, allowing farmers and gardeners to optimize their watering schedules and prevent over or under-watering. The sensor can also be used to monitor soil moisture levels in areas where water conservation is important, such as in drought-prone regions.
Package included
5 X Capacitive Soil Moisture Sensors
5 X Analog Sensor Cables
Hardware Connections: Connect the sensor to your microcontroller (e.g., Arduin0):
VCC: 3.3V or 5V (3.3V is recommended for most capacitive models to avoid overvoltage)
GND: GND
AOUT (Analog Out): A0
Calibration: Capacitive sensors are not linear. You must determine the specific values for your sensor:
The capacitance of the soil moisture sensor varies depending on the amount of moisture present in the soil.
When the soil is dry, the capacitance of the sensor is low, while when the soil is wet, the capacitance is high.
Dry Soil/Air: Note the analog Read (A0) value (e.g., 615)
Wet Soil/Water: Note the analog Read (A0) value (e.g.,272)
Note: Do not submerge the electronic component part; only the probe should be in water.
Circuit schematic diagram of V1.2
The soil moisture sensor can be connected to an analog input on a microcontroller or other electronic circuit to provide a voltage or current signal that corresponds to the soil moisture level.
