Enter end include transducing signal input positive terminal PIR+ and transducing signal input negative terminal PIR_, respectively with difference A/D converter module
First input end and the second input be connected, be suitably applied the pyroelectric sensor field of the function containing difference output, its manage
Pin explanation is as shown in table 2：
Human body sensing chip pin explanation for infrared thermal release electric of the table 2 containing positive-negative input end
| Sequence number | Title | Function declaration |
| 1 | VDD | Power positive end |
| 2 | GND | Ground |
| 3 | PIR+ | Transducing signal input positive terminal |
| 4 | PIR_ | Transducing signal input negative terminal |
| 5 | OUTPUT | Signal output part |
The human body sensing chip operation principle for infrared thermal release electric shown in Fig. 2 is as follows：
First, pyroelectric sensor output signal is sent to PIR+ and PIR_ ends, by difference ADC (ADC, modulus
Converter) by sensor export analog signal be converted into data signal.The data signal filters out dry by digital filtering module
Signal and garbage signal are disturbed, only retains the human-induced signal needed for chip.The human-induced signal passes through control circuit mould again
Block is carried out after controlling accordingly, and the signal output part pin of chip is output to by output circuit module.
The control function of control circuit module can realize timing, blocking time, repeated trigger mode, sensitivity,
The functions such as output level effective means, output PWM.Wherein, repeated trigger mode includes repeatable triggering and not reproducible triggering
Two states.Repeatable triggering state refers to that after pyroelectric sensor senses human body the output of chip OUTPUT pin is effective
Control signal, effective control signal is just exported always when human body signal has chip always, until being not sensed by the human body moment
Rise and start timing, the working condition of closing control signal after the timing.Not reproducible triggering state refers to when heat
Release electric infrared human body inductor and timing is begun to after human body is sensed, the closing control signal after the timing
Working condition.When after timing, chip enters blocking time, during this period of time, transducing signal input is (just,
Negative terminal) any signal can not all make OUTPUT ends export effective status, so as to effectively suppress load handoff procedure in produce
Various interference.
Output level effective means include high level effectively and effective two kinds of low level.In addition, the chip can also be realized
Nobody when, OUTPUT ends export PWM (Pulse Width Modulation, pulse width modulation) signal of small dutycycle；Sense
When should arrive human body, the pwm signal of big space rate is exported, so as to realize the control function of human body sensing, such as unmanned dark lighting,
The bright function of someone's light.Maximum distance that sensitivity can typically be sensed with PIR systems identifies.
Letter is deposited in the memory that the control circuit module of chip of the present invention can be by changing mask plate or change built-in chip type
