HiLetgo 5pcs HC-SR501 Human Sensor Module Pyroelectric Infrared PIR Motion Detector Modules
HC-SR501 Body Sensor Module
Specifications:
Operating voltage range: DC 4.5-20V
Angle Sensor: <100 ° cone angle Lens size
Level output:High3.3V/Low0V
sensor:Diameter:23mm(Default)
BoardDimensions:32mm*24mm
Operation Temp: -15-+70 degrees
Delay time: 5-200S(adjustable) the range is (0.xx second to tens of second)
Block time: 2.5S(default)Can be made a range(0.xx to tens of seconds
At default sensitivity it would trigger easily from 8-10' away

Precautions:
The DC operating voltage must meet the values we require. Both too high and too low will affect the performance of the module.
Try to keep the body away from the sensing area as far as possible.
The human body sensing module is recommended to be installed in a sealed box, otherwise it may always have an output signa.
The human body sensing module can only work indoors and avoid direct glare.
The sensing area avoids facing the heating appliances and objects as well as the sundries or clothes which are easy to be blown by the wind.

Application:
It can automatically and quickly open various types of incandescent, fluorescent lamps, buzzer, automatic doors, electric fans,automatic washing machine and dryer machines and other devices,is a hightech products. Especially suitable for enterprises, hotels, shopping malls, warehouses and family aisles,corridors and other sensitive Sense of region, or for the security zone automatic lighting, lighting and alarm systems.
