Microwave Radar Sensor


New product

Αυτός ο αισθητήρας έχει σχεδιαστεί ως εναλλακτική λύση για τους κοινούς αισθητήρες κίνησης PIR που χρησιμοποιούνται ευρέως σε συναγερμούς και φώτα ασφαλείας. Όπως και ο αισθητήρας PIR, αυτός ο αισθητήρας ανιχνεύει επίσης μόνο κινήσεις εντός του εύρους ανίχνευσής του. Αλλά αντί να ανιχνεύει την ακτινοβολία του μαύρου σώματος από ένα κινούμενο άτομο, αυτός ο αισθητήρας χρησιμοποιεί μια τεχνική "ραντάρ μικροκυμάτων Doppler" για να ανιχνεύσει κινούμενα αντικείμενα.

The module has the characteristics of high sensitivity, high induction distance, high reliability, large induction angle, wide power supply voltage range, etc. it is widely used in various kinds of human body induction lighting and alarm and so on.

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 comtinuously output the high level TTL signel when there is motion. 360 degree no blind angle detection and maximum 7m sensoring distance with adjustable delay time and sensitivity.

It has a sensitivity range of ~7 meters. When triggered, its TTL-level output (OUT) pin will switch from LOW (0 V) to HIGH (3.3 V) for a finite time (2 to 3 s) before returning to its idle (LOW) state.

It is perfect for DIY microwave motion sensor light switch, human sensor toys, smart security devices, etc.

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:

  • 3V3:3V3 power output
  • GND:ground
  • OUT:control output;when detect moving objects,it will output high level
  • VIN:input voltage,4-28V
  • CDS:enable control chip,lower than 0.7V,OUT will output low level all the time
