Fast response time
Impressed by how quickly this detects temperature changes. I'm using it on a small robot to avoid hot surfaces, and it reacts instantly. The 90-degree FOV is perfect for close-range detection.

Perfect for Arduino projects
This sensor works flawlessly with my Arduino Uno. The library support is excellent, and the readings are surprisingly accurate for the price point. Setup took less than 10 minutes.

Solid build quality
The PCB looks clean and the soldering points are well-defined. It has survived several drops during prototyping without any issues. Highly recommend for students and makers.

Works well with Raspberry Pi
Connected easily to my Pi 4 via I2C. Just had to enable the interface in raspi-config. Readings are consistent, though it does get slightly warm itself after prolonged use.

Good value, minor calibration needed
Great module overall. I noticed a slight offset in readings initially, but after running a simple calibration script, it became very reliable. Ideal for hobbyist thermal imaging.

Great for smart home sensors
Using this to monitor appliance temperatures in my smart home setup. It integrates perfectly with ESPHome. The non-contact feature is a huge plus for safety.
Q: Is 5V logic safe for the data pins?
A: The module includes a voltage regulator for power, but the SDA/SCL lines are generally 3.3V tolerant. If using a 5V microcontroller without 5V-tolerant pins, a logic level converter is recommended.
Q: Can this measure body temperature accurately?
A: While it can detect surface temperature, it is designed for industrial and object sensing. For medical applications, please use devices specifically certified for clinical use.
Q: Does this module come with a library for Arduino?
A: Yes, it is compatible with the popular Adafruit MLX90614 library, which can be easily installed via the Arduino Library Manager.
Q: What is the maximum distance for accurate measurement?
A: Accuracy depends on the target size relative to the Field of View. For best results, the target should fill the sensor's view; typically effective within 2cm to 30cm depending on object size.
Q: Does it work in complete darkness?
A: Yes, since this is a passive infrared sensor that detects emitted heat radiation, it functions perfectly regardless of ambient light conditions.
