Description

• RCWL-0516 rcwl 0516 microwave radar motion sensor human sensor body sensor module.
• RCWL-0516 Microwave Radar Sensor: Operating voltage: 4.0-28.0V; Output power supply: 3.3V; Detection distance:5-7M.
• Transmission Signal Processing Control Chip: RCWL-9196, equipped with doppler radar technology which is specially designed for detecting objects' motion.
• The RCWL-0516 radar sensor module has the features 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 etc.
• Package Contents: 12pcs rcwl-0516 microwave radar sensor module with pin header.

Specification:
Operate Voltage: 4-28V
Output Voltage:3.2-3.4V
Operate Current: 2.8mA (Typical); 3mA (Max)
Detection Distance:5-7M
Transmit Power: 20mW (Typical); 30mW (Max)
Output Voltage Driving Capacity: 100mA
Trigger Way:Repeat Trigger
Output Control Level: 0V~3.3V
Operate Temperature: -20~80
Storage Temperature: -40~100

Adjustment Part Introduction:
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

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

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
VIN: Input voltage,4-28V
CDS: Enable control chip,lower than 0.7V,OUT will output low level all the time

Attention:
1. There should no shelter in front of the sensing surface.
2. Front and rear sensing surface space to set aside more than 1cm.
3. The module carrier plane and install as flat line.
4. Effective in a certain detection area.
5. The component side of the module is positive sensing face, the opposite is negative sensing surface. Negative sensing surface sensing less effective.
6. The microwave module cannot be applied on a large scale in the same area, otherwise, it will be mutual interference, and the distance between individual modules should more than 1M.
