Intelligent infrared detectors and working methods

The present invention provides an intelligent infrared detectors and a working method, the probe comprising a controller trigger signal of the pyroelectric sensor and receiving an electrical sensor output heat release, wherein the infrared-rays detector is provided with a thermopile sensor, the controller receiving when the trigger signal to the pyroelectric sensor output from the thermopile sensor is turned on, and the alarm is provided, in the thermopile sensor detects a difference between the current temperature and the substrate temperature is greater than this threshold, the alarm controller controls the alarm signal . The method comprises thermopile background temperature detection detection area of ​​the sensor, and enter the sleep state, the pyroelectric sensor detects the detection region temperature is changed, and if so, open the thermopile sensor, the temperature inside the thermopile sensor detects the detection region and determines when the difference between the detected temperature and the temperature of the background is greater than the threshold, the alarm signals an alarm. Infrared detector of the present invention, low power consumption, and can detect an infrared signal source stationary.
