XH-M214 12V Humidity Controller with Soil Sensor and LED Module
The XH-M214 is a humidity controller designed for automatic irrigation systems that helps maintain optimal soil conditions through an integrated sensor and LED module for easy viewing.
Main features:
- Operating voltage: DC 12V, ideal for small and medium irrigation systems.
- Humidity range: 20-99% RH, with a control accuracy of 1% RH for exact monitoring.
- Control output: Output switch with current control capacity up to 10 A.
- Compact and durable design: Dimensions of 5,2 x 4,3 x 1,2 cm and approximate weight of 35 grams, made with durable materials.
- Easy installation: The probe is inserted directly into the soil to measure moisture accurately.
- Digital display and LED module: Allow you to easily view and adjust humidity settings to start and stop irrigation.
Operation and use:
This controller works by measuring soil moisture and automatically activating the pump or solenoid valve when humidity falls below the set value (adjustable using the SET and +/- buttons). When the desired humidity level is reached, the system stops watering to prevent overwatering.
The device allows you to adjust three key parameters:
- F0: Start humidity to activate the pump or valve.
- F1: Stop humidity to stop watering.
- F2: Humidity correction to synchronise multiple modules and improve accuracy.
This system is compatible with electronics and automation projects, including applications with Arduino, making it easy to integrate into custom irrigation systems.
Typical applications:
- Residential gardens and vegetable plots.
- Automated irrigation systems for small-scale agriculture.
- DIY and maker projects that require precise humidity control.
Package contents:
- 1 x XH-M214 12V humidity controller with soil sensor and LED module.
This humidity controller is a practical solution for optimising water use and keeping plants in ideal conditions, ensuring efficiency and ease of use.

Customer Questions & Answers
What voltage, current and humidity limits can it handle during continuous operation?
It operates on a 12 V DC supply. Loads of up to 10 A are supported on the relay output. The humidity measurement and control range is 20% to 99% RH, with an accuracy of ±1% RH. Exceeding these limits could compromise the integrity of the device.
What types of pumps or solenoid valves can be connected directly, and what electrical compatibility should I consider?
The XH-M214 can control 12 V DC loads up to a maximum of 10 A, such as water pumps or low-voltage solenoid valves. For higher-voltage or higher-power equipment, an external relay is required. Check that your equipment load does not exceed the electrical limits to avoid damage.
What recommendations are there for installing the humidity probe and ensuring reliable measurements?
It is recommended to insert the probe firmly into the soil, avoiding excessively corrosive environments or high salinity to extend its service life. It is ideal to clean the probe periodically and avoid using it in heavy clay soils, as these can affect the measurement.
What are the common issues in typical installations and how are they resolved?
The most common errors include incorrect connections (check the wiring diagram) or measurement faults caused by dirt on the probe, which can be resolved by cleaning it and ensuring good contact with the soil. In addition, measuring outside the recommended range may lead to inaccurate readings or premature cut-off.
How do I set the humidity value on the XH-M214?
It is adjusted using the "SET" key to select the parameter (F0 for start, F1 for stop) and the +/- keys to set the desired humidity value.
Is the XH-M214 compatible with Arduino systems?
Yes, the XH-M214 can be integrated into Arduino projects to automate watering based on soil moisture.
What humidity range does this controller detect?
The humidity range is 20% to 99% RH with a control accuracy of 1% RH.
What type of output does the controller have?
It has an output switch that can control a current of up to 10 A to activate pumps or solenoid valves.
What is included in the XH-M214 package?
It includes 1 XH-M214 humidity controller with soil sensor and LED module for an automatic irrigation system.
