SOIL-SENSING COMPONENT3.3V ANALOG
A 3.3V analog capacitive soil-moisture sensor with an integrated 150 cm Micro-USB cable for Arduino and other 3.3V-controller projects.
- 3.3V DC input only
- 0–3V analog output
- 150 cm integrated cable
- Dual-sided capacitive sensing area
- Sensor, adapter and four-pin header included
Power the sensor from 3.3V DC only. Never apply 5V or connect its Micro-USB plug to a computer, charger, power bank, or standard USB power socket.
SOIL-SENSING COMPONENT
Analog soil-moisture sensing for 3.3V projects
This capacitive module produces an analog output for a compatible microcontroller or ADC. Its response depends on the soil and installation, so the project must establish dry and wet reference values.

KEY DETAILS
What this item is designed to do
Analog integration
Read the 0–3V signal with a suitable analog input; a Raspberry Pi requires a separate ADC.
Project calibration
Record readings in the actual soil and placement, then choose thresholds based on observed behavior.
What is included
- 1 PlantMate capacitive soil-moisture sensor
- 1 Micro-USB adapter
- 1 four-pin header
Check before ordering
- 3.3V input only; do not apply 5V
- Controller must accept a 0–3V analog signal
- Raspberry Pi boards require an external ADC
- Keep connectors and exposed electronics dry

Calibration and voltage note
Soil type, salinity, pot shape, sensor depth and watering placement can all change the reading. Use only a 3.3V supply and calibrate the assembled project before relying on thresholds.
HD VIDEO DEMO
See the sensor respond in real time
Watch the PlantMate sensor work with a classic Arduino Nano and a 0.91-inch OLED, including dry, water, and potted-soil readings.
The demonstration uses dry raw 824 and water raw 413 as reference values. Calibrate the sensor in the actual soil, pot, and installation used in your project. Watch on YouTube.

Building 2 raised bed garden with Plantmate moisture sensors. Among all sensors tested, Plantmate, you guys got it.
One thing, do not apply 5v on sensors, as I blew one. Other than that, great product.
