Operation principle：
After power on circuitry, when nobody enters people's pyroelectric sensor PIR monitoring ranges, the processing of rpyroelectric infrared transducing signal is integrated
Circuit BISS0001 is in reset state, control signal output（2nd pin）VO exports low level, and Q2 is in cut-off state, PCB
The illumination LED of plate periphery placement does not work, and controller is in the monitoring state.When someone enters people's pyroelectric sensor PIR monitoring ranges
And when moving, heat is released infrared signal refraction on pyroelectric sensor PIR by Nie Er lens, and pyroelectric sensor PIR is by human body
The infrared ray change given out is converted to electric signal output, and output signal frequency is 0.1~10Hz.R3 and R5 constitutes light-operated electricity
Road, for detecting ambient light illumination.Low resistance is presented by natural light irradiation in photo resistance on daytime R5, when the pin current potentials of BISS0001 the 9th
During Vo ＜ 0.2VDD, chip is in triggering illegal state, so as to block trigger signal Vs.Therefore the late-class circuit such as BISS000l is not
Work, illumination LED lamp bead does not work.When evening or dark ambient light, R5 resistances increase, as the pin level position ＞ of BISSOOOI the 9th
During 0.2Vdd, BISSOOOI is in the monitoring state, and output end is still low level.If now someone moves in PIR monitoring ranges
Dynamic, PIR just exports the electric signal changed with human motion, and it is only that this signal is sent to BISS0001 chip internals by resistance R14
Found high defeated people's impedance op-amps OP1 input 11N+（14 pin）, after the preposition amplifications of OP1, exported by the 16th pin, through C7
The 13rd pin 2IN- ends are coupled to, then are amplified through the 2nd grade of operational amplifier OP2 of chip internal, it is then two-way through chip internal
Amplitude discriminator processing, exports the back off timer TX of effective start trigger signal chip internal, finally by state controller from
The pin of BISSO001 the 2nd export high-level control signal, light Q2 conducting driving peripheral LEDs luminous.The pin of BISS0001 the 2nd are exported
The high-level control signal time is equal to the delay time of circuit, and it is determined by delay cell R12 or RT1 and C7 time constant
Fixed, output delay time Tx is adjusted by outside R12 and C7 size, is worth for Tx ≈ 24576xR12C7；Trigger blocking time Ti
By outside R11 and C8 size adjustment, it is worth for Ti ≈ 24xR11C8.
Time shown in figure is 55s.Because the pin of chip the 1st connects high level, circuit, which is in, allows repeated trigger state, that is, is prolonging
When the time（55s）Interior, a very important person moves below lamp, and circuit is just triggered again, and the 2nd pin exports a pulsewidth and is again
55s high level signal.So as long as someone is movable under such illuminator, LED bulb can be lighted all the time.Someone leaves
Afterwards, after delay 55s, circuit reset, illuminating lamp automatic distinguishing.
