Description:The human body sensor switch is an infrared detection controller that uses infrared detection to control the load switch. The user can install the human body sensor in an appropriate environment according to actual needs1. Connect the load line first, then the power line; make sure that there is no short circuit between the connecting lines before powering on;2. There is a time setting knob on the back of the controller. Rotate the knob to set the number of minutes to delay the switch off. When someone is detectedThe load light is turned on when the person is away for the set number of minutes, the load light is automatically turned off.3. The signal output line and input line of the controller should be connected correctly.Specifications: Working temperature: -20-60 Power supply voltage: 10.5-16V or 21-32V Output voltage: 10.5-16V or 21-32V Output: 1 loop Sensing distance: 8 M The angle of response: 60 degrees Output current:
