Parameters:

Wide voltage working range: 4-28V

Compared with traditional infrared induction PIR, it has penetration detection capability

Blocking time, distance adjustable

Output 3.3V power supply

Pin definition:

3V3: 3V3 power output

GND: ground

OUT: control output, high level of moving object output is detected

VIN: Input voltage, 4-28V

CDS: enable control chip, lower than 0.7V, OUT always outputs low level

Description of adjustment part:

1: C-TM

Adjust the repeated trigger time. The default trigger time is 2S. Increasing the capacitance will increase the repetition trigger time. The actual repetition trigger time can be calculated as follows:

Paste capacitance at C-TM, test the frequency f of pin 3 of 91 96, and repeat trigger time T=(1/f) * 32768

2: R-GN

The detection distance is adjusted and the resistance is connected to reduce the detection distance. Not connected. The detection distance is about 7M. Connect a 1M resistor. The detection distance is about 5M. The customer can adjust according to the actual situation.

3: R-CDS

The internal VC is connected in parallel with the internal 1M resistor to the CDS pin (i.e., pin 9 of 9196) through the R-CDS. The CDS is connected with a photosensitive resistor, which can turn off the module detection function at night. The R-CDS value can be set according to the actual required ambient brightness.

Package include：
