This Is an Infrared thermometer a non-contact temperature measurement sensor develop by Melexis microelectronics integrated system, code name MLX90614. The MLX90614 has thermopile detector chip and the signal conditioning ASSP are integrated in a low noise amplifier, 17 bit ADS and DSP unit. This integrated device is calibrated with a digital and pulse with modulation and SMBus output at 10bit PWM continuously transmit the measured temperature in range of -20 to 120 degree Celsius with an output resolution of 0.14 degree Celsius. MLX90614 support 2 supply voltage option 5v or 3v. The 5v can be easily adopted to operate from a higher supply voltage to 8-16v refer to datasheet. This device can be used or implement in non-contact temperature sensing, thermal comport sensor for mobile & air conditioning control system, sensing elements for commercial, residential, and industrial, defogging , automotive blind angle detections, home appliances, movement detection, farming, body temperature monitoring and temperature measuring acquisition for healthcare.
