Sensor microwave radar RCWL-0516 human body detection doppler gerak

Deskripsi Produk
RCWL-0516 Microwave Radar Sensor Switch Module Body Induction 4-28V 100mA

Sensor yg menggunakan teknik Radar Doppler untuk mendeteksi keberadaan objek yg bergerak.

Teknik ini lebih bagus daripada PIR (Passive Infrared) dan Ultrasonic karena tidak terpengaruh oleh cahaya dan suhu lingkungan dan memiliki daya tembus yg lebih baik.

Banyak digunakan pada berbagai peralatan elektronik yg mendeteksi kehadiran manusia seperti
1. Pencahayaan otomatis on off
2. Alarm anti pencurian
3. dll

Adjustment Part Introduction:
1.C-TM :
Adjust repeat trigger time,default trigger time is 2s;increasing capacitor's capacity will make repeat trigger time longer;and actual counting trigger time can operate as below :
Stick capacitor on C-TM,test 9196 3-pin frequency F,repeat trigger time T=(1/f)*32768

2.R-GN
Detection distance adjustment;connect with resistor and detection distance will become shorter;if not connect,detection distance is 7m;if connect with 1M ohm resistor,detection distance is 5m

3.R-CDS
Internal VCC parallel connect with internal 1M ohm resistor to CDS pin (that is 196 9-pin) by R-CDS ,CDS connects with photoresistor,you can close detection function at night

Pin Definition:
1. 3V3: 3V3 power output
2. GND: ground
3. OUT: control output;when detect moving objects,it will output high level
4. VIN: input voltage,4-2
