AS081-3P Three pyroelectric infrared sensors

As081-3p is a CMOS integrated PIR (passive infra red) processor chip with low power consumption. Its internal structure
The frame is designed by mixed mode of analog and digital mixed circuit, which is very stable in all cases.
As081-3p adopts the third generation PIR human body thermoluminescence infrared detection technology scheme, with a built-in high-precision algorithm unit, which can be self-adaptive
At present, the environment, filtering out environmental interference, effective extraction of human signals, the farthest sensing distance up to 20 meters. The practical application circuit is quite simple.
R & D and production do not need debugging, greatly reducing production costs and saving space.
As081-3p can be externally connected with 3 probes, 2 probes or 1 probe for detection, with a wide sensing range.
Product characteristics
· industrial standard, good stability, strong anti-interference, wide working temperature range, conducive to passing various certifications.
The built-in operational amplifier can be matched with a variety of PIR sensors for signal preprocessing.
The peripheral circuit of the built-in operational amplifier needs no debugging during R & D and production, saving development time and production cost.
The built-in high-precision algorithm unit can self adjust and adapt to the current environment, and effectively distinguish human signal and interference signal.
The sensing distance is far, and the probability of misoperation is far lower than that of traditional control chip.
It can be detected by external 3 probes, 2 probes or 1 probe, with a wide sensing range.
Adjustable sensitivity, more convenient to use.
Built in high-precision crystal oscillator.
The practical application circuit is quite simple, the consistency of mass production products is good, the repair rate is low, and the volume of finished products can be very small.
Ssap16 package, small chip size.
· environmental protection packaging, not only meeting the EU ROHS standard, but also meeting the halogen-free green environmental protection standard (such as Sony SS-00259, apple
069-1857, Dell a00-00).
Product application
· automatic energy-saving lighting for gardens, garages, corridors, stairs and other occasions.
· monitoring, alarm and doorbell system for home, store, office, factory and other occasions.
Automatic switch system of exhaust fan and ceiling fan.
Energy saving and control system of digital products such as electronic photo album, display, digital camera, hunting camera, etc.
Intelligent toy control.
