MLX90614ESF Non-Contact Human Body Infrared Temperature Measurement Module

Description

The MLX90614 is an Infra Red thermometer for noncontact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASSP are integrated in the same TO-39 can. Thanks to its low noise amplifier, 17-bit ADC and powerful DSP unit, a high accuracy and resolution of the thermometer is achieved.

The thermometer comes factory calibrated with a digital PWM and SMBus (System Management Bus) output. As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in range of -20…120˚C, with an output resolution of 0.14˚C. The factory default POR setting is SMBus.

The MLX90614 is built from 2 chips developed and manufactured by Melexis

• The Infra Red thermopile detector MLX81101
• The signal conditioning ASSP MLX90302, specially designed to process the output of IR sensor.

Applications:

1.High precision non-contact temperature measurements
