Melexis | EVB90614

The EVB90614 evaluation board is an easy interface between the MLX90614 infrared thermometer in TO-can and a PC. The evaluation board and it's software enables the user to make temperature measurements using a PC interface.

The MLX90614 is an Infra Red 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 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. 

With the evaluation board the user can also reconfigure the MLX90614 infrared thermometer for different applications by modifying the interface type, temperature ranges, refresh rate and integration time.
