1. automatic: when someone enters the sensing range is input high level, people leaving the induction range is automatically delayed closing high level. Output low level. 4. power consumption: quiescent current 65, particularly suitable for battery-powered appliances. 3. wide operating voltage range: default voltage DC5V to 20V 2. induction blackout time (default setting: 0.2 sec): after each induction the induction module output (high level low level), you can immediately set a blackout time, during this time the sensor does not receive any sensor signal. This feature can be achieved (sensor output and blockade times) the interval between work, can be applied to interval detection products; at the same time this function can inhibit various disturbances load in the process of switching. 5. high level signal output: can be easily docked with the circuit.
