1. The document contains a circuit diagram with 9 PIR motion sensors labeled PIR101 through PIR901 connected to an input board. 2. The motion sensors are connected in parallel with 470 ohm resistors to 9 corresponding signal conditioning circuits labeled COR1 through COR9. 3. The signal conditioning circuits are connected to a microcontroller board to detect motion and transmit signals from the 9 PIR sensors.
