This product adopts a high sensitivity detector, integrate circuit and SMT; It gathers automatic, convenient, safe, energy-saving, practical functions; It has a wide detection range made up of up and down, left and right service field; It utilizes human motion infrared rays as control signal sources when one enters the detection field, it will start the controlled load at once; It can identify day and night automatically; It is easy to install and its usage is wide; It has the function of power indication and detection indication. Specification: 1.Detection Range: 180 degree 2.Power Consumption: 0.45W (work) 0.1W (static) 3.Detection Distance:max.12m 4.IP65 Function: Detection field: The wide detection range is made up of up and down, left and right, the detection range could be adjusted according to your desire, but the moving orientation in detection field has great relation with the sensitivity. Identify day and night automatically: The ambient light of product could be adjusted according to your desire: when turn to SUN (max), it will work day and night, when turn it to MOON (min), it will only work in the ambient light less than 3LUX. As for adjustment, please refer to testing way. Time-delay is added continually: When it receives the second induction signals after the first induction, it will compute time once more on the rest of the first time-delay basis (set time). Time-delay is adjustable: It can be set according to your desire, the minimum is 10sec ±3sec, and the maximum is 7min±2min.
