Geekstory HC-SR501 PIR Infrared Sensor Body Infrared Motion Module for Arduino Raspberry Pi(Pack of 5pcs)

♦Human body infrared sensor module is an automatic control product based on infrared technology. The working principle: Automatic induction: When someone enters its induction range, enter the high level, people leave the sensor range is automatically delayed off high. Output low
♦Features: high sensitivity, high reliability, ultra low power consumption, ultra low voltage operation mode.Operating voltage range: DC 4.5-20V (Attention: Although the human body is not in front of the module, but the human body from the module is too close to the module can also be caused by the sensor output. The human body sensor can only work indoors and the work environment should avoid the sun, a strong direct light exposure.)
♦Two trigger modes: L is not repeatable, H is repeatable, the default is H. Output high-level signal: can be easily with various types of circuits to achieve docking
♦Induction blocking time 0.5-200 seconds (adjustable); After each sensing output (high level goes low), the sensing module can be followed by a blocking time, during which it is sensed The device does not receive any sense signals
♦Widely used in various types of automatic induction electrical equipment. For example, Security Products, Human body sensor lighting industrial automation and control, etc. It can automatically and quickly open various types of incandescent, fluorescent lamps, buzzer, automatic doors, etc. compatible with Arduino, Raspberry Pi, PIC and more
