1PCS SR501 HC-SR501 Adjust IR Pyroelectric Infrared PIR Module Motion Sensor Detector Module,HC-SR501 Green KIT

Description

• Automatic induction: When someone enters its induction range, enter the high level, people leave the sensor range is automatically delayed off high. Output low.
• Output high-level signal: can be easily with various types of circuits to achieve docking.
• Light and other interference should be avoided Directly close the surface of the lens module, so as not to introduce interference with the signal to produce malfunction; use of the environment as far as possible to avoid Free flow of wind, the wind will cause interference to the sensor.
• the sensor should be installed so that the direction of the probe dual And the direction of human activity as much as possible parallel to ensure that the body has been through Probe dual element induction.
• the module of the probe (PIR) can be mounted on the other side of the circuit board. The probe can also be extended with a two-core shielded cable, the length should be less than 20 cm as well.

Origin:CN(Origin)
Material:Metal
Type:Temperature Sensor
Theory:Hall Sensor
Model Number:HC-SR501

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: that is, 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 is sensed The device 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.
Wide operating voltage range: the default operating voltage DC5V to 20V
Micro-power: Quiescent current 65 microamps, especially for dry battery-powered electrical products.
