This is the RCWL-0516 a mini-radar motion sensor module that features the RCWL-9196 chip. The modules function is based on doppler radar. It will automatically output a high-level TTL signal for a 2s duration whenever it detects a motion within its 5-8m range. The module operates with a wide range of input voltages from 4V to 28VDC. Microwave radar sensors can have a much higher sensitivity and better detection rate than traditional IR sensors.
– RCWL-9196 chip supporting input voltages of 4-28VDC
