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 0.14C, while the TWI interface has a resolution of 0.02C. The MLX90614 is factory calibrated in wide temperature ranges: -40 to 85C for the ambient temperature and -70 to 382.2C 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 0.5C around room temperatures.
This devices comes in an industry standard TO-39 package. We’re carrying the 3V version of this sensor.
