HC-SR501 Human Body Pyroelectricity Infrared PIR Motion Detector Sensor Module
Working voltage: DC5V to 20V
Static consumption: 65 microamps
level output: 3.3V high, low 0V
Time delay: Adjustable (0.3 seconds to 18 seconds)
Blockade of the time: 0.2 seconds
Trigger: L can not be duplicated, H can be repeated, the default value of H
Sensing range: less than 120 degrees cone angle less than 7 m
Working temperature: -15 to +70 degrees
PCB Dimensions: 32 * 24mm ,screw pitch 28mm ,screw aperture 2mm, sensor lens Dimensions: (diameter): 23mm (default)
Automatic induction: when a person enters the sensing range of input high level, people leave the sensing range will automatically delay the closing high level. Low level output voltage.
Photosensitive control ( optional ): module reserve position, can be set to a photosensitive control, day or when light is strong not induction. A photosensitive control as optional features, the factory has not installed the photosensitive resistance. If necessary, please be purchased photosensitive resistance self installation.
Two triggers: L can not be repeated, H repeatable. Can jumper option, the default is H.
A. May not repeat trigger mode: induction output high level, delay time is over, the output will be automatically changes from high level to low level.
B. Repeatable trigger mode: induction output high level, the delay time period, if the body is in its sensing range, the output will always maintain a high level, until the people left after the delay will be the high level to low level ( induction module detects human body every time events will automatically postpone a delay time, and to the last active time delay starting point ).
As a sensing block time ( default:0.2 seconds ): induction module in each of the first sensing output ( high level to low level ), can be followed by setting a blockade of the time, in this period of time the sensor does not receive any induction signal. This function can be achieved ( inductive output time and blocking time ) the interval operation, can be applied to interval detection products; at the same time this function can effectively suppress the load switching process in the various interference
Wide working voltage range: default working voltage of DC5V to 20V Micro power consumption.
Static current65 microamps, especially suitable for dry battery powered electrical products.
Outputs a high level signal: convenient and various types of circuit
