3. Exquisite and compact appearance

4. Wide range of power supply voltage and other characteristics

5. Widely used in various human body induction lighting and burglar alarm occasions

Parameters:

Wide voltage working range: 4-28V

Compared with traditional infrared sensor PIR, it has the ability to penetrate detection

Blocking time and distance adjustable

3.3V power supply output available

Pin definition:

3V3: 3V3 power output

GND: Ground

OUT: control output, high level output when a moving object is detected

VIN: Input voltage, 4-28V

CDS: enable control chip, below 0.7V, OUT always outputs low

Description of the regulation section:

1: C-TM

Adjust the repeat trigger time, the default trigger time is 2S. increasing the capacitor capacity will increase the repeat trigger time, the actual calculation of the repeat trigger time can be done as follows:

C-TM with capacitor, test 91 96 pin 3 frequency f, repeat trigger time T= (1/f) *32768

2: R-GN

The detection distance is adjusted by connecting a resistor, the detection distance becomes smaller. If not connected, the detection distance is about 7 M. If a 1 M resistor is connected, the detection distance is about 5 M. Customers can adjust according to the actual situation.

3: R-CDS

Internal VC through R-CDS and internal 1M resistor in parallel to the CDS foot (i.e. 9196's 9 feet), CDS at the connection of photoresistor, you can turn off the module detection function at night. The R-CDS value can be set according to the actual required ambient brightness.
