HC-SR501 Infrared PIR Motion Sensor Pyroelectric Module For Arduino Raspberry Pi

Description

Features:
Fully automatic induction: When someone enters its sensing range, it inputs a high level, and when the person leaves the sensing range, it automatically delays to turn off the high level. The output is low.
Photosensitive control (optional): The module is reserved for position, and the photosensitive control can be set. It is not sensed during the day or when the light is strong. Photosensitive control is an optional feature and no photoresistor is installed at the factory. If necessary, please purchase the photoresistor separately to install it yourself.
Two trigger modes: L can not be repeated, H can be repeated. Jumper selection, default is H.
A. Non-repeatable trigger mode: After the high level of the sense output, the output will automatically change from high level to low level when the delay time is over.
B. Repeatable trigger mode: After the high level of the sense output, during the delay time period, if the human body is active within its sensing range, its output will remain high until the person leaves the delay. The level changes to a low level (the sensing module automatically delays a delay period after each activity of the human body is detected, and the time of the last activity is the starting point of the delay time).
With induction blocking time (default setting: 3-4 seconds): After each sensing output (high level becomes low level), the sensing module can set a blocking time immediately, during which time The device does not receive any sensing signals. This function can be used to achieve interval detection (induction output time and blocking time), which can be applied to interval detection products; at the same time, this function can effectively suppress various interferences generated during load switching.
Wide operating voltage range: default operating voltage DC5V to 20V
Micro power consumption: quiescent current 65 microamps, especially suitable for dry battery powered electrical products.
Output high level signal: It can be easily connected with various circuits.
