A build-in thermal relay function further extends the easy implementation of wide variety of freezing/boiling prevention and alert systems, as well as thermostats (no MCU is needed).Dual zone non contact temperature measurements are available via a single line (extended PWM). Systems with more than 100 devices can be built with only two signal lines. The digital sensor interface can be either a power-up-and-measure PWM or an enhanced access SMBus compatible protocol.

The low power consumption during operation and the low current draw during sleep mode make the thermometer ideally suited for handheld mobile applications.The thermometer is available in automotive grade and can use two different packages for wider applications’ coverage. The sensors are housed in an industry standard TO39 package for both single- and dual-zone IR thermometers.An embedded error checking and correction mechanism provides high memory reliability. The user can program the internal object emissivity correction for objects with a low emissivity.The MLX90614 supports versatile customization to a very wide range of temperatures, power supplies and refresh rates.These sensors also have a very short stabilization time compared to other types of thermopile sensors, which is of importance if one needs an accurate measurement in conditions where the ambient temperature can change quickly. The high thermal stability of the MLX90614-xCx make this part highly suited in applications where secondary heat sources can heat up the sensor.The MLX90614 is a ready-to use low-cost non contact thermometer provided from Melexis with output data linearly dependent on the object temperature with high accuracy and extended resolution.The library supports the I2C communication.
