Infrared sensor module features extended temperature range Vishay Intertechnology has introduced an extended temperature "E" option for its TSSP77038 infrared (IR) sensor module in the Heimdall package. Designed to meet the requirements of outdoor applications, the TSSP77038ETR has been enhanced with a storage temperature range of -40 °C to +110 °C and an operating temperature range of -30 °C to +85 °C. Standard packages for IR sensor modules offer limited storage and operating temperature ranges of -25 °C to +85 °C. With the robust design of its Heimdall package, the TSSP77038ETR is able to handle a wider temperature range, making the device suitable in applications exposed to direct sunlight and large temperature variations..
