Melexis, Nashua, NH, offers the MLX90614ESF-DCH and MLX90614ESF-DCI contactless MEMS IR temperature sensors for automotive, medical, industrial, and consumer applications. The sensors use a secondary sensor to measure thermal disturbances and compensate the measurement result with internal digital electronics, avoiding the error induced by fast temperature variations and/or thermal gradients. A refractive silicon lens lets the devices achieve fields of view down to 5°. Accuracy is 0.2°C in human body temperature measurement. Applications include ear and forehead thermometers, microwave ovens, green air-conditioning systems, process control and maintenance systems, medical blood analyzers, and mobile phones.
