Review: Easy to use, good accuracy - I bought one of these to add to a mobile weather instrument to record road surface temps. I drilled a hole in a small project case for the lens, attached neodymium magnets to the top of the case, and when I want to collect data I just slap the case under the car and go. So far I’ve had no problems, and the temperature values are within 2 degrees of manual comparisons using a handheld IR thermometer. The programming is simple when using the Adafruit library.
Review: Convenient for prototyping, works lower than 3.3V - I'm working on a personal project to build a non-contact thermometer as a concrete project to help teach me PIC programming, I2C, PCB design, and enclosure design for 3D printing. This breakout board has been convenient for prototyping on a breadboard (see picture). Also the price of the board rival the quantity one price for the sensor alone, so it's a good deal. Some things to note. The MLX90614 sensor comes in different sub-models. This board uses the BAA sub-model, which is what I wanted. It's not strictly medical accuracy--for that you need the more expensive DCI sub-model--but IMHO is good enough to screen for high fevers. I'm not allowed to put a non-desertcart URL here, so you'll have to google for the Melexis datasheet on the MLX90614; you'll have to read the datasheet to understand how to control the sensor. For what it's worth, I'm controlling the sensor in my application from a PIC16LF19156 8-bit microcontroller with a built-in I2C/SMBus interface. The board has a 3.3V regulator on it, but I've run it at 2.8V without modification. According to the datasheet, the sensor needs at least 2.6V to operate. The board contains pull-up resistors for SCL/SDA and a filter capacitor across power/ground. This board has behaved just as I expected and has been very convenient. I'm glad I bought it.

## Features

- MLX90614 is an infrared thermometer for non-contact temperature measurements.
- Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can.
- Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer.
- The thermometer comes factory calibrated with a digital SMBus output giving full access to the measured temperature in the complete temperature range(s) with a resolution of 0.02°C.
- The user can configure the digital output to be pulse width modulation (PWM). As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20 to 120°C, with an output resolution of 0.14°C.

### ⭐⭐⭐⭐ Works - but not exactly what I expected
*by P***N on July 6, 2022*

There are a few things to consider here - this model comes in different packages, different voltages etc. and this seller doesn't differentiate. This seems to be a 5V module with a regular to 3.3v - which means those of us that uses 3.3V devices are "not getting the full bang for the buck". I'll remove the regulator and give the unit the voltage it requires, and hopefully it solves what I'm seeing. I have this unit working - took a bit of tweaking though. There are several Arduino libraries that covers this unit, but the actual coding isn't too complex if you had to make it from scratch; I ended up using the DFRobot_MLX90614 library since it uses the native Wire interface and doesn't mess with everything else I have (hint - careful with Adafruit) and ESPHOME is a relatively simple setup with this library. HOWEVER, every initial reading of either ambient or object temperature fails. All subsequent reads work just fine, so in the end that was a simple fix. I suspect this is due to using 3.3V on the VIN pin, so I'm hoping this goes away when that's fixed. What I'm not so happy about is the temperature difference. Even sitting just a foot away from the sensor it barely measures above room temperature (about 2 degrees centigrade). I almost have to put my hand over the sensor (not touching) to see it go up significantly. So the spectrum it covers seems extremely wide. If the device keeps the sensor values relatively constant, I can still use any temperature difference to detect a human presence but that's for more testing. You should know what you're getting into - it's definitely not on the cheaper side when coming to sensor objects for basic Arduino stuff.
