Thermoelectric infrared sensor subassembly and sensor system

The utility model provides a thermoelectric infrared sensor subassembly and sensor system relates to the sensor field. Thermoelectric infrared sensor subassembly is used for detecting the regional wife's of awaiting measuring existence, including master reference and at least one auxiliary setter's sensilla. The master reference is used for detecting the human infrared who treats in the detectionarea. At least one auxiliary setter's sensilla is used for detecting the human infrared who treats detection area outlying specified region, and each auxiliary setter's sensilla corresponds a specified region. Wherein, the detection area of master reference is greater than the detection area of each auxiliary setter's sensilla, and main, auxiliary setter's sensilla communication is connected. Sensor system includes master reference, at least a pair sensor, controller and controlled device. The utility model discloses a thermoelectric infrared sensor subassembly and system judge someone or nobody through the sequence t
