This mini doppler radar sensor module is equipped with supporting DC
4-28V wide voltage This is a mini radar motion sensor module is equipped
with RCWL-9196 chip based on the doppler microwave induction
technology. It will automatically continuously output the high level TTL signal when there is motion. 360 degree no blind angle detection and
maximum 7m sensoring distance with adjustable delay time and
sensitivity. It is perfect for DIY microwave motion sensor light switch,
human sensor toys, smart security devices, etc.
Specifications:
Working Voltage: DC 4-28V
Working Current: 2.8mA
Detecting Distance:5-7 meter
Transmitting Power: 20mW
Output Signal:TTL(high level 3.3V, low level 0V)
Board Size: 35.9 X 17.3mm/1.41 X 0.68inch
Pin Instructions:
1. 3V3: support output 3.3V voltage, driving current is 100mA
2. GND: ground
3. OUT: controlling signal output, when detect the subject, it will output high level(3.3V),otherwise output low level(0V)
4. VIN: power supply input(4-28V)
5. CDS: trigger signal control: less than 0.7V, OUT output low level, over 0.7V work normally.
Connect the LDR can turn off the detecting function at night.
Regulation Function Instructions:
1. C-TM: regulate the repeat trigger time, default time is 2s, add the SMD capacitor to extend the repeat trigger time.
Repeat trigger time calculation: install the SMD capacitor, then test the 9196 3th pin frequency f, the trigger time T=
2.
R-GN: regulate the detecting distance,connect the resistor the
detecting distance will will short.(default 7m, connect 1M resistor, the
detecting distance will be about 5M)
3. R-CDS: the VCC is in parallel
connection with CDS(namely 9196 9th pin) through R-CDS. Connect the LDR
at the R-CDS to turn off the detecting function at night.
