This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low. This unit works great from 5 to 12V. You can also install a jumper wire past the 5V regulator on board to make this unit work at 3.3V. Sensor uses 1.6mA@3.3V.
The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low. The connector is slightly odd but has a 0.1″ pitch female connector making it compatible with jumper wires and 0.1″ male headers.

1.Automatic induction: when someone enters its sensing range input high, people leave the sensor range automatic delay off high.Output low.
2.Photosensitive control (optional): module is reserved for the location, you can set the photosensitive control, daytime or light sensing. The photosensitive control optional features not installed at the factory photoresistor. If necessary, please purchase separately photoresistor install it yourself.
3.Two trigger modes: L can not be repeated, H can be repeated.Default is H. A. not repeat the trigger mode: the sensor output high, the delay time has elapsed, the output automatically from high to low. B. repeatable trigger mode: the sensor output high, the delay period, if human activities within its sensing range, the output will always remain high until people leave only delay the high level goes low (sensor module detected after every activity of the body’s automatic postponed a delay period of time, and the last time activities as the starting point of the delay time).
4.Induced blockade time (default setting: 0.2 seconds): sensing module in every sensor output (high to low) followed by set up a blockade of the time, in this period of time the sensor is not receiving any induction signal. This feature can be achieved both of the (inductive output time and the blocking time) interval can be applied to the interval detection products; This feature can effectively suppress the various interference generated in the process of load switching.
5.Wide operating voltage range: default Voltage DC 5V to 12V.
6. Micro-power: quiescent current of 65 microamps, particularly suitable for battery-powered electrical products.
7. Output high signal: easy to achieve docking with the various types of circuits.
