Description: Melexis' MLX90614ESF-BAA is an infrared thermometer designed for non-contact temperature sensing. An internal 17-bit ADC and a powerful DSP contribute to the MLX90614’s high accuracy and resolution. It has a huge number of applications including body temperature measurment and movement detection.
The MLX90614 provides two methods of output: PWM and SMBus (i.e. TWI, I2C). The 10-bit PWM output provides a resolution of 0.14°C, while the TWI interface has a resolution of 0.02°C. The MLX90614 is factory calibrated in wide temperature ranges: -40 to 85°C for the ambient temperature and -70 to 382.2°C for the object temperature. The measured value is the average temperature of all objects in the Field Of View of the sensor. The MLX90614 offers a standard accuracy of 0.5°C around room temperatures.
This devices comes in an industry standard TO-39 package. We’re carrying the 3V version of this sensor.

I was able to get readings from the sensor over I2C in the course of a day and was able to confirm its accuracy with an ice cube and boiling water. I’m adding a Fresnel lens so it can measure temperature accurately from a distance. Gonna have a lot of fun with this little guy!
Wide temperature range, steady output under steady temperature conditions, and surprisingly resistant to spilling soda on the lense. Repeatedly.
Does exactly what it says on the tin.
Be aware that this is a 3v device, and not suitable for use with 5v Arduinos.
Also, the imaging angle is rather wide - make sure to account for that in your application.
