MLX90614
Melexis Infrared Temperature Sensor (Thermopile) | Object Temperature -70°C...+380°C | Field of View 5°...90° (FOV) | Operating voltage 3V or 5V
Melexis Infrared Temperature Sensor (Thermopile)
Intelligent infrared thermometer for precise and non-contact temperature measurement in automotive, industrial or medical applications.
The 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.
