Description: RCWL-0516 Microwave Radar Sensor
RCWL-0516 is a mini doppler radar microwave motion sensor module which can act as an alternative to a PIR motion sensor. It will continuously output the high level TTL signel when there is motion. It has a maximum range of 9m with adjustable delay time and sensitivity. It is perfect for DIY microwave motion sensor light switch, human sensor toys, smart security devices, etc.Features:
1, Transmission signal processing control chip RCWL-91962, Wide operating voltage range: 4.0-28.0V3, Compared with the traditional infrared feeling PIR, with the penetrating detection capability4, Block time, distance adjustable5, Output 3.3V power supply6, Board size: 35.9mmx17.3mmApplication Design Note:
1, the sensing face in front of the gold without any shelter.2, front and rear sensing surface space to set aside more than 1CM3, the module carrier plane and install as flat line4, a certain application of effective detection area5, the component side of the module is positive sensing face, the opposite is negative sensing surface. Negative sensing surface sensing less effective6, microwave modules can not be large-scale applications in the same area, otherwise there will be mutual interference. Between single individuals over distance greater than 1MCharacteristic:
Operating Voltage: 4-28VOperating Current: 2.8mA (typical); 3mA (max)Detection Distance: 5-9mTransmitting Power: 20mW (typical); 30mW (max)Output Voltage: 3.2-3.4VOutput Voltage Driving Capacity: 100mATrigger Way: repeat triggerOutput Control Low Level: 0VOutput Control High Level: 3.3VOperating Temperature: -20~80 celsiusStorage Temperature: -40~100 celsiusBoard Layout:
Application Design Note:
1, the sensing face in front of the gold without any shelter.2, front and rear sensing surface space to set aside more than 1CM3, the module carrier plane and install as flat line4, a certain application of effective detection area5, the component side of the module is positive sensing face, the opposite is negative sensing surface. Negative sensing surface sensing less effective6, microwave modules can not be large-scale applications in the same area, otherwise there will be mutual interference. Between single individuals over distance greater than 1MAdjustment 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)*327682.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 5m3.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 nightDocuments:
