Reliable temperature control
I used this to build a simple fan controller for my 3D printer enclosure. The digital output switches cleanly at the set point. Highly recommended for DIY automation.

Perfect for my Arduino project
This module worked flawlessly right out of the box. The analog output is stable, and adjusting the threshold with the potentiometer was very intuitive. Great value for the price.

Good sensor, instructions could be better
The hardware quality is solid and readings are accurate compared to my calibrated thermometer. I had to look up a tutorial online to get the code running, but once set up, it works great.

Great for learning electronics
Bought five of these for a university project. All of them functioned perfectly. The form factor is compact and fits easily into small enclosures.

Excellent sensitivity adjustment
The ability to fine-tune the trigger point makes this versatile for different applications. I'm using it to monitor my reptile terrarium temperature. Very satisfied.

Solid performance
Response time is quick enough for most ambient temperature monitoring tasks. The only minor issue is that the pins are slightly close together, making wiring a bit tight.
Q: Can I use this directly with a 5V Raspberry Pi GPIO?
A: The digital output is compatible, but please ensure you configure the GPIO correctly. For analog readings, you will need an external ADC since Raspberry Pi lacks built-in analog inputs.
Q: Is the cable length of the probe extendable?
A: Yes, you can extend the wires, but keep in mind that very long extensions may introduce noise or voltage drop affecting accuracy.
Q: What is the accuracy of the temperature reading?
A: Typical accuracy is within ±1°C for the range of 0°C to 70°C, depending on your calibration and MCU ADC resolution.
Q: Does this support I2C communication?
A: No, this module outputs analog voltage and digital TTL signals only. It does not have an I2C interface.
Q: Does this module come with the thermistor probe attached?
A: Yes, the NTC thermistor probe is pre-soldered and connected to the module board.
