Problems solved by technology

[0003] There is no special tester for pyroelectric infrared sensors in the existing market, and most of the test methods use human body and induction modules to simulate on-site tests. The test efficiency is low and the parameters of pyroelectric infrared sensors cannot be tested. Many infrared alarms When the manufacturer uses the pyroelectric infrared sensor, there is a problem that the pyroelectric infrared sensor does not match the sensing module, and the stability of different products cannot be guaranteed during use, so a pyroelectric infrared sensor tester is needed to solve the above problems

Abstract

The invention belongs to the technical field of test equipment and provides a multi-channel pyroelectricity infrared sensor tester. The multi-channel pyroelectricity infrared sensor tester is characterized in that: a sealed specific constant-temperature black body device with a hole in the front part is arranged in a box body; a transmission channel consisting of a circuit board, a grating device, a radiation channel and a test plug-in unit is arranged between the hole end face of a black body and the front end of the box body; and a voltage meter, a control switch and a control conversion switch are arranged on the front of the box body. By the multi-channel pyroelectricity infrared sensor tester, a parameter of a pyroelectricity infrared sensor can be tested accurately, so the pyroelectricity infrared sensor can be matched with an induction module perfectly; and the stability of the multi-channel pyroelectricity infrared sensor tester can be achieved.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, and relates to a tester, in particular to a multi-channel pyroelectric infrared sensor tester. Background technique [0002] Pyroelectric infrared sensor is a heat-sensitive detector designed according to the pyroelectric effect. It is a sensor that converts infrared radiation signals into electrical signals and has been widely used in various industries. However, [0003] There is no special tester for pyroelectric infrared sensors in the existing market, and most of the test methods use human body and induction modules to simulate on-site tests. The test efficiency is low and the parameters of pyroelectric infrared sensors cannot be tested. Many infrared alarms When the manufacturer uses the pyroelectric infrared sensor, there is a problem that the pyroelectric infrared sensor does not match the sensing module, and the stability of different products cannot be guaranteed during use, ...
