TI’s industry leading family of temperature sensors offers the best in class in every category from accuracy, power, size, and integration. TI’s temperature sensing family also offers a wide range of products including temperature switches, local sensors, remote sensors, fan controllers, and even contactless temperature sensing.
Contactless Sensors
Measure the temperature of an object off of the PCB without wires. Developed through TI’s expertise in MEMS technology, the TMP006 is the first of a new class of ultra-small, low power, and low cost passive infrared temperature sensors. It has 90% lower power consumption and is more than 95% smaller than existing solutions, making contactless temperature measurement possible in completely new markets and applications.
