Features: brand new and high quality 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. Two trigger modes: l not repeatable, h can be repeated. Jumper option defaults to h. 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. Wide operating voltage range: default voltage DC5V to 20V. Power consumption: quiescent current 65, particularly suitable for battery-powered appliances. High level signal output: can be easily docked with the circuit. Specifications: Working voltage: DC5V to 20V Static power consumption: 65 Output level: high 3.3V, low 0V Delay time: adjustable (0.3s~18s) Embargo time: 0.2s Trigger mode: l not repeatable, h can be repeated, the default value for h Induction range: less than 120 degree cone angle, up to 7 meters Working temperature:- -15~+70 PCB size: 23mm Note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
