AS082 Digital pyroelectric induction chip

Functional description
As082 is a CMOS integrated PIR (passive infra red) controller chip with low power consumption. Its internal framework
It is designed by mixed mode of analog and digital mixed circuit, which is very stable in all cases.
As082 adopts the third generation PIR human body thermoluminescence infrared detection technology scheme, with a built-in high-precision algorithm unit, which can be self adjusted to adapt to the current situation
Environment, filter out environmental interference, effectively extract human signal, the farthest sensing distance is up to 20 meters. The practical application circuit is quite simple.
Development and production do not need debugging, greatly reducing production costs and saving space.
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.
Built in high-precision crystal oscillator.
· built in shielding time timer to effectively inhibit repeated misoperation.
The output delay time of control signal is adjustable, precise and wide.
No load working current can be less than 50ua (customized), with excellent power saving performance, suitable for battery power supply.
External phototriode or photoresistor, not working during the day.
· L1, L2, N1 and N2 versions are set with fast test mode to facilitate the test of semi-finished modules.
· the control signal output of L1 and L2 versions is made into PWM output, which is convenient to control the led to be slightly on, fully on, gradually on and off.
Special functions can be customized according to customer requirements.
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.
Msop10 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.
