-SR312 Sensor Module: Operating Voltage: DC 2.7V - 12V; Static Consumption: Less than 0.1mA. This AM312 Human Sensor Module is a digital intelligent automatic control product based on passive infrared technology for the human body, small in size, very easy to install. These human sensor modules have high sensitivity and high reliability; Low consumption and anti-interference. Repeatable trigger mode: The output from the human sensor module will remain high when a human body is within the module's sensing range, until the person leaves after the delay, then it will become low ((. The sensor module detects the human body. Any activity will automatically extend a time delay, and the last activity time as the starting point for the delay time). Wide Applications: This AM312 Mini Human Sensor Module can be used for security products, toys, lighting, industrial automation and controllers, etc. Color: black Material: ABS + Electronic components Size: 13.79 x 11.30 x 2.39 cm Package Contents: 10 x -SR312 IR Pyroelectric Infrared PIR Motion Sensor Module 1 x 10 Pin Male to Female Cable Only the above package content, other products are not included.
