This is Micro SR602 Human Body Sensing Module Pyroelectric Infrared Sensor.
Automatic induction: When a person enters its sensing range, it outputs a high level. When the person leaves the sensing range it automatically delays the high level and outputs a low level.
Low power consumption, ultra small size, easy for embedded installation.
Internal digital signal processing, anti-interference enhancement.
High sensitivity and high reliability, can be widely used in automatic sensing circuit technical parameters.
Repeatable trigger mode: After the high level of the sense output, during the delay time period, if the human body is active in its sensing range, its output will remain high until the person leaves, and the delay will be high. It becomes 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).
The high-level time of the output of this product is adjustable, 1.8 seconds to 1 hour. The output time set at the factory is 1.8 seconds.
If you need to change, you can change a chip resistor. The blocking time is also 1.8 seconds and cannot be adjusted.
The module output timing is: output high level for 2 seconds after power-on, then go low and enter standby mode.
