Reliable switching
Been running this for a month controlling a cooling fan. No false triggers and the relay clicks firmly.

Great for automotive use
Installed this to monitor my engine bay temp. The relay switches reliably when the threshold is met. Very happy with the purchase.

Perfect for DIY electronics
Used this with an Arduino project. The digital output makes it very simple to interface without complex coding.

Good module, short wires
Functionality is perfect for my HVAC project. Only wish the probe wires were a bit longer, but I extended them myself.

Accurate and responsive
Tested against a calibrated thermometer and it was within a degree. Easy to adjust the trigger point with the onboard pot.
