HC-SR312 PIR Motion Sensor

Features:

• Low power consumption, 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
• Anti-interference enhancement, internal use of digital signal processing, direct high and low level output
• Repeatable trigger mode: after induction output high level, the time delay period, if there is the human body in the scope of its induction activities, its output will always keep a high level, until the people left after the delay, it becomes low level (that is, the sensing module automatically delays a delay period after detecting each activity of the human body, and takes the time of the last activity as the starting point of the delay time)
