Overview

Product Overview

Capacitive soil moisture sensor V1.2 is a plant monitoring probe that detects how wet or dry soil is by sensing changes in capacitance, making it ideal for smart irrigation, automatic watering systems, greenhouse control, indoor plant care, and garden prototyping. Unlike basic resistive probes, this soil moisture sensor is designed for more stable long-term moisture detection in pots, planters, and beds. Use the V1.2 sensor in Arduino, ESP32, and other microcontroller projects to trigger pumps, log soil conditions, or add moisture feedback to home automation, classroom experiments, and IoT gardening builds.

Questions & answers

Frequently asked questions

Does this soil moisture sensor work with Arduino and ESP32?

Yes. It is intended for Arduino, ESP32, and other microcontroller projects that can read a soil moisture sensor signal and use it for logging, alerts, pump control, or home automation feedback.

Does this sensor require soldering before use?

ShillehTek sells pre-soldered IoT components, so this module is meant to be ready for jumper-wire prototyping without soldering headers first. You still need to connect it to a compatible controller and write or load code to read it.

How does the capacitive soil sensor interface electrically?

This is a capacitive moisture probe, so it detects soil wetness through capacitance changes rather than measuring resistance through exposed metal electrodes. In a microcontroller build, it is used as a sensor input for moisture-based decisions.

Can it control an automatic plant watering system?

Yes. It is suitable for smart irrigation and automatic watering projects where a microcontroller monitors soil conditions and triggers a pump, valve, alert, or automation rule when the soil becomes too dry.

Why do readings differ between plants or soil types?

Different soil mixes, pot sizes, and probe placement can change readings, so set dry and wet reference levels in your own planter before relying on thresholds. Keep the probe inserted consistently for more repeatable monitoring.
