Sensor measures temperature without contact

MLX90614 infrared thermometer is a small, cost effective noncontact thermometer that delivers a fully calibrated, digital temperature reading of a remote object. It integrates an IR sensor and a custom signal-conditioning chip in one TO-can package. The sensing element is an automotive-grade silicon chip with a thin, micromachined membrane heated by the IR radiation of a distant object. The sensor transmits the result to the user's application either over an SMBus or by a continuous PWM signal. The MLX90614 applies advanced low noise amplifiers, a 17-bit ADC, and powerful DSP unit in its signal conditioning chip allowing a wide operating temperature range of -40°C to 125°C.
