Accurate but instructions could be better
The temperature reading is quite accurate compared to my multimeter. I wish the manual had more details on the potentiometer adjustment for the threshold.

Great for DIY Automotive Projects
This module works perfectly for controlling my cooling fans. The relay clicks loudly but feels solid. Wiring was straightforward with the provided diagram.

Works but cables are short
The module functions correctly, but the sensor cable is shorter than I expected. I had to extend it for my specific application.

Product as described
Fast shipping and the item matches the description exactly. The 3-wire mode worked fine for my simple setup. Good value for the price.

Reliable relay switching
I've been using this for a month in a humid environment. The probe is sealed well and the relay switches cleanly without chatter.
Q: What is the wire color code for connection?
A: Typically Red is VCC, Black is GND, and Yellow or White is the Signal output. Please refer to the silkscreen on the PCB for confirmation.
Q: Can this module operate on a 12V vehicle battery system?
A: Yes, the operating voltage range is DC 5V to 24V, so it is fully compatible with standard 12V automotive systems.
Q: Can I adjust the temperature trigger point?
A: Yes, there is a blue potentiometer on the board that allows you to calibrate the temperature threshold at which the relay switches.
Q: Is the temperature probe waterproof?
A: The stainless steel probe head is IP65 rated and water-resistant, but the PCB module itself should be kept in a dry enclosure.
Q: Does the relay make a loud noise when switching?
A: Yes, it uses a mechanical relay which produces an audible click when activated. This is normal operation for this type of component.
