Motion sensor
Information
Due to its design, the PIR motion sensor module is very easy to use because it already has the components installed. Raspberry Pi motion detectors in home automation and/or outdoor applications (as a classic outdoor motion detector) are easier than ever to implement.
This Arduino/Raspberry Pi motion sensor responds and moves, with the “strength” of movement controlled by an adjustable resistor (potentiometer). So you can set the motion sensor very sensitive, or try to avoid “noise”. As soon as something moves, a signal is sent that can be received and responded by the Raspberry Pi.
Setup
In order to use the Motion sensor use the following settings:
Mandatory
Hardware : Motion sensor
Address : Enter the physical pin number on which the device is connected
Ex: 27
Or when used with an IO expander use format: pcf857[4/5]-[IO-expander-port],[I2C_address],[I2C_buss] where I2C_buss is optional
Ex:pcf8575-9,0x4c,3
Other settings can be found at the button setup information
