Soil Moisture Sensor with 12V Relay Control Module

Product Description

• Using the high-quality soil sensor produced by our company to test the soil moisture, the surface is treated with nickel plating, and the widened sensing area can improve the conductivity, prevent the problem of easy rusting in contact with the soil, and prolong the service life.
• The product can control the humidity of the soil in a wide range, and the corresponding threshold is controlled by the potentiometer. When the humidity is lower than the set value, the relay is activated, and when the temperature is higher than the set value, the relay is disconnected
• The product has a delay function, delay 3-5 seconds, when the humidity is detected in the critical state, the relay will not flash, and the stroboscopic phenomenon occurs.
• The product adopts Songle high-quality relay, which can withstand 1500W load and meet the requirements of most people.
• The product has a power indicator and a relay pull-in indication.

Electrical Parameters

Supply voltage: 12VDC input current: greater than 100mA

Load: 250V 10A AC or 30V 10A DC (less than this range of current can be used)

Note: The available relay module types are: SRD-12VDC-SL-C and JQC-3FF-S-Z. You may get any of it randomly.

Detailed information is available in the documentation.

Module Instructions

1. The sensor is suitable for moisture detection of soil.

2. The blue potentiometer in the module is used for the threshold adjustment of soil moisture. When it is adjusted clockwise, the humidity will be controlled, and the counterclockwise will be smaller.

3. Because this module has a delay function, when adjusting the humidity value, it needs to wait for 5-8 seconds for each adjustment. Look at the change of the relay, and the green LED light also has corresponding changes until it meets the requirements.
