Features:
1, Transmission signal processing control chip RCWL-9196 2, Wide operating voltage range: 4.0-28.0V 3, Compared with the traditional infrared feeling PIR, with the penetrating detection capability 4, Block time, distance adjustable 5, Output 3.3V power supply 6, Board size: 35.9mmx17.3mm
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 1CM 3, the module carrier plane and install as flat line 4, a certain application of effective 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, 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 1M
This microwave "doppler"sensor works by detecting the interference of reflected microwaves caused by the human body. It seems to work well at up to about 5 metres. This data sheet may be useful: https://img.filipeflop.com/files/download/Datasheet_rcwl-0516.pdf
