Contactless Temperature Detection Thermopile IR Sensor With Optical Lens STP11DF59L5

The STP11DF59L5 infrared thermopile sensor for non-contact temperature measurement is a thermopile sensor having an output signal voltage directly proportional to the incident infrared (IR) radiation power. Thanks to the anti-electromagnetic interference design, STP11DF59L5 is robust for all kinds of application environment. The sensor window integrated optical lens improves the sensor‘s DS ratio through optical optimization design . The STP11DF59L5 comprising a new type CMOS compatible thermopile sensor chip features good sensitivity, small temperature coefficient of sensitivity as well as high reproducibility and reliability. A high-precision thermistor reference chip is also integrated for ambient temperature compensation.
