The pyroelectric infrared sensor is one kind can examine infrared which the human body launches to output the electrical signal the sensor, it can compose guards against the intrusion alarm unit or each kind of automated energy conservation installment.The sensor contains two to connect or the parallel pyroelectric Yuan mutually.Moreover makes two electric polarization directions just right opposite, the environment background radiation releases the part to two heat to have the same function nearly, causes it to produce releases the electricity effect to counterbalance mutually, therefore detector non-signal output.Once the human invades in the search coverage, human body infrared radiation through partial mirror surface focusing, and by pyroelectric Yuan receive, but two piece of pyroelectric Yuan receive the quantity of heat is different, pyroelectric also different, cannot counterbalance, reports to the police after the signal processing.The human body all has the constant body temperature, generally in 37 degrees, therefore can send out specific wave length 10μM about infrared, the passive form infrared probe head is depends on surveys the human body to launch 10μM about infrared to carry on the work.The human body launches 10μM about infrared you the light filter to strengthen after the Philippine putty gathers in the infrared induction source.The infrared induction source usually uses the pyroelectric part, this kind of part when receives the human body infrared radiation temperature changes can lose the electric charge to be balanced, outward releases the electric charge, after the latter continued wire goes via examination processing to be able to produce the alarm.
