MLX90614 family
Single and Dual Zone
Infra Red Thermometer in TO-39
9 Unique Features
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.
It supports versatile customization to a very wide range of temperatures, power supplies and refresh rates.
The user can program the internal object emissivity correction for objects with a low emissivity. An embedded
error checking and correction mechanism provides high memory reliability.
The sensors are housed in an industry standard TO39 package for both single- and dual-zone IR
thermometers. The thermometer is available in automotive grade and can use two different packages for
wider applications’ coverage.
The low power consumption and sleep mode make the thermometer ideally suited for handheld mobile
applications.
The digital sensor interface can be either a power-up-and-measure PWM or an enhanced access SMBus
compatible protocol. Systems with more than 100 devices can be built with only two signal lines. Dual zone
non contact temperature measurements are available via a single line (extended PWM).
A built-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).
