HC-SR501 PIR IR Passive Infrared Motion Detector Sensor Module / Arduino DIY

Description

HC-SR501 PIR IR Passive Infrared Motion Detector Sensor Module
Features
Size:
Rectangular
Output:
Digital pulse high (3V) when triggered (motion detected) digital low when idle (no motion detected). Pulse lengths are determined by resistors and capacitors on the PCB and differ from sensor to sensor.
Sensitivity range:
up to 20 feet (6 meters) 110° x 70° detection range
Power supply:
5V-12V input voltage for most modules (they have a 3.3V regulator), but 5V is ideal in case the regulator has different specs
Automatic induction: When someone enters its induction range, it enters high level. After people leave the sensor range, it automatically delayed off high and then goes into output low.
Photosensitive control (optional): the module can be set to photosensitive control, strong light during the day or not induction. Photosensitive control is optional, the factory did not install photosensitive resistor. If necessary, please buy a separate photosensitive resistor to install
Two trigger modes: L is not repeatable, H is repeatable. Can be jumper selected, the default is H.
non-repeatable trigger mode: the induction output high, the delay time is over, the output will automatically change from high to low.
Repeated trigger mode: After sensing the output high, in the delay time period, if the human body in its sensing range of activities, its output will remain high until the delay after the person will leave the high The level changes to low level (the sensing module automatically delays a delay time after every activity of the human body, and takes the time of the last activity as the starting point of the delay time)
Induction blocking time (default setting: 3-4 seconds): After each sensing output (high level goes low), the sensing module can be followed by a blocking time, during which it does not receive any sense signals. This function can be used to achieve the interval between the sensing output time and the blocking time. It can be applied to the interval detection products. At the same time, this function can effectively suppress all kinds of interference in the process of load switching.
Micro-power: Quiescent current 65 micro-amps, especially for dry battery-powered electrical products
Output high-level signal: can be easily with various types of circuits to achieve docking
Instructions for use
Induction module power about one minute after the initialization time. At this time the module will output 0-3 times a minute, a minute into the standby state
Light and other interference should be avoided Directly close the surface of the lens module, so that it does not introduce interference with the signal to produce malfunction; Avoid free flow of wind, the wind will cause interference to the sensor.
The DC voltage must meet our requirements, too high and too low will affect the performance of the module. The power supply must be a good regulator filter, such as computer USB power, mobile phone charger power supply. It is recommended that customers use the power transformer and the regulator through the three-terminal voltage regulator and then through the 220UF and 0.1UF capacitor filter power supply.
The human body sensor module can only work indoors and outdoor environment should be avoided. A strong direct light exposure interfere with its working.
