YFH-AD012 is a pyroelectric infrared sensor that integrates digital intelligent control circuitry and human detection sensitive elements in an electromagnetic shield. The body detection sensor couples the sensed human movement signal through a very high impedance differential input circuit to the digital intelligent integrated circuit chip, which converts the signal into a 15-bit ADC digital signal and outputs a delayed REL level when the PIR signal exceeds a selected digital threshold. The product can be widely used in intelligent lighting, security, home decoration and other fields requiring automatic sensor control.

The human body sensor module color with built-in AC110-280V voltage input with its own conversion DC constant voltage for the work of the microcontroller, constant current output drive LED;
The load must not exceed the function required in the specification, the circuit board hipped design alignment AC also uses isolated way infrared module test and use precautions
1. there must not be other things blocking on the infrared cover, otherwise it will cause no induction;
2. Because the module is AC220 high voltage input, the circuit board components must not have debris and metal wire;
3. lightly hold and place, avoid intense vibration, the human body module to keep flat and not deformed;
4. infrared module to maintain independent use of space, the surrounding space to maintain a free space of more than 3mm interval;
5. about 2s initialization noise analysis time after power on, during this period is not normal induction work;
1. assembled high-voltage infrared module, the component surface must not be in contact with the septic tank, otherwise it will cause damage to the board;;
2. strictly forbidden to work with electricity, so as to avoid action error, wrong connection, burned circuit or electric shock;
3. avoid installation in the sun and rain to prevent damage and affect the service life;
