Direct, non-contact temperature sensing saves HVAC energy

The Melexis MLX90614 comprises infrared non-contact temperature sensors for automotive as well as industrial or domestic sensing applications.

The devices measure temperature directly, allowing systems such as vehicle climate controls to operate more efficiently and reduce energy consumption by up to 40%. In an automotive application, for example, the sensor assures that the compressor in the system can work at a constant level without large changes in loading. This results in higher efficiency of the climate-control system, enabling lower fuel consumption.

This small and cost-effective non-contact thermometer delivers a fully-calibrated, digital temperature reading for a remote object. It achieves this feature by integrating an infrared sensor and a custom signal conditioning chip in one TO-style package. This implementation solves the traditional challenges surrounding complexity and reliability that have historically prevented the use of infrared sensing in automotive applications.

The built-in intelligence, high accuracy and wide operating-temperature range of the MLX90614 allow OEMs to easily integrate non-contact temperature measurement in automotive air conditioning, as well as applications such as room heaters, home appliances, handheld devices and medical equipment.
