Specifically, in the figure, NPN triodes Q1 and Q2 are MC8050, an optocoupler is PC817, a resistor R2 is a matching load required by a sensor AM312, a chip TL084 is a four-operational amplifier chip, four groups of operational amplifiers are a1, a2, A3 and a4, wherein a1 and a2 constitute a band-pass filter and gain amplifier of an induction module, input signals of the band-pass filter and gain amplifier are taken from two ends of R2, Al and a2 are all connected into an inverting input feedback amplifier, voltage gain of the induction module amplifier is determined by R6, R4, Rl0 and R7, voltage gain of an a1 amplifier is a ratio of feedback resistor R6/R4, and then a decibel logarithm is taken; the voltage gain of the A2 amplifier is the ratio of the feedback resistors R10/R7, and then is logarithmic in decibels.

The resistors R3, R5, R8 and R9 have the same resistance and constitute a bias circuit that biases the two-stage operational amplifier at 1/2 × V2, where V2 is the input voltage of the circuit. The operational amplifiers A3, A4 and the peripheral devices R11, R12, R13, R14, R15, D1 and D2 constitute a double-limit comparator circuit. The reference voltage of the comparator is determined by dividing the voltage by R11, R12, R13, and R14. The voltage reference of the inverting input terminal pin 9 of the operational amplifier a3 is (R12+ R13+ R14)/(R11+ R12+ R13+ R14) × V2, and the voltage of the non-inverting input terminal pin 12 of a4 is R14/(R11+ R12+ R13+ R14) × V2.

When the sensor does not sense the infrared ray of the human body, the output voltage of the amplifier A2 is 1/2V 2, because the voltage of the non-inverting input end of the A2 is taken from the voltage 1/2V 2 at the central point of the voltage dividing circuit formed by the R8 and the R9, the resistances of the resistors R8 and R9 are the same, and the voltage of the inverting end of the A2 is also 1/2V 2 according to the virtual short virtual break principle of the non-inverting end of the operational amplifier, no electric signal is generated by the sensor, no current flows through the resistor R10, and the output voltage of the A2 is also 1/2V 2. At this time, the inverting terminal voltage of A3 is greater than 1/2 × V2, and A3 outputs low level; the voltage at the non-inverting terminal of a4 is less than 1/2 × V2, and a4 also outputs low.

The diodes D1 and D2 in the circuit diagram are provided to prevent short-circuiting the high level of one of A3 and a4 when the other outputs a low level, and therefore, the diodes serve as isolation and can be selected from model 1N 4150. When the A3 outputs a low level and the a4 also outputs a low level, the resistor R16 and the photo resistor RL form a series circuit, the voltage division of the photo resistor RL is zero, the base of the NPN triode MC8050 is at a low level and cannot meet the turn-on condition, and the 8 LED night lights from L1 to L8 are not bright.

When a person moves in front of the sensor, the Fresnel lens can focus infrared rays released by the human body and the infrared rays are received by the infrared receiving sensor AM312 behind the Fresnel lens, the infrared signals with the intensity changed are converted into low-frequency alternating current signals by the sensor AM312, and the Fresnel lens can select different detection angle specifications such as 60 degrees, 100 degrees, 120 degrees and the like so as to meet the requirements of different places. After the sensor electrical signal is amplified by the circuit, the operational amplifier a2 outputs positive and negative pulse signals corresponding to 1/2 × V2.

At this time, if a2 outputs a positive pulse signal whose amplitude is larger than the reference voltage of the inverting input terminal of the operational amplifier A3 and the reference voltage of the non-inverting input terminal of a4, A3 outputs a high level, and a4 outputs a low level, the double-limit comparator circuit outputs a high level. Similarly, when a2 outputs a negative pulse signal, a4 outputs a high level and A3 outputs a low level. Therefore, when a human body moves in front of the sensor, the A3 and the A4 in the comparator alternately output high levels, the resistance value of the photosensitive resistor RL is very small in the daytime, the divided voltage cannot meet the opening condition of the NPN triode MC8050, the resistance value of the photosensitive resistor RL is far larger than that of the resistor R16 at night, the divided voltage meets the opening condition of the triode MC8050, the collector and the emitter of the resistor are conducted, and the 8 LED night lights from L1 to L8 are turned on.

Sensor AM312 fixes time delay 2 seconds, if there is the human body at sensor induction range activity, its two limit comparator circuit's output will keep the high level always, and the night-light is lighted always, and when the sensor can't detect human infrared ray along with people's walking, sensor AM312 postpones 2 seconds back night-lights and extinguishes.

In addition, the wall socket can open the sound prompt button 418, which is used for monitoring whether a house door of a resident is hidden by a stranger or not, or people often forget to turn off the power supply of an electric appliance in time when using the wall socket to charge a mobile phone and a battery car, and an electric water heater and other different electricity demands, and aiming at the situations, the sound prompt button 418S1 can be opened, once the pyroelectric infrared sensor senses that a human body passes through, the comparators A3 and A4 in the circuit alternately output high levels, the pins 1 and 2 of the optocoupler PC817 are conducted, so that the pins 3 and 4 are conducted, the voice chip HFC5219 is electrified, the OUT pin outputs an electric signal, after the power of the NPN triode Q2 is amplified, the loudspeaker is pushed to give a sound prompt, and the loudspeaker can be selected to be a micro moving coil loudspeaker. The user hears suggestion sound and can know that there is the electrical apparatus at work, and convenient suggestion user in time cuts off the power supply when necessary, finishes like bathroom electric water heater heating, often forgets the closing power supply when the user uses, has brought the potential safety hazard for the user, to the utility model discloses, detect by pyroelectric infrared sensor when the human body, the speaker carries out audible cue, and the user knows electric water heater by audible cue and is using in the use to and use the water heater after closing the power supply.
