FYP 2 : WEEK 10

Title of activity

- Construct the main circuit of Intelligent fire fighting system.

Objective

- This circuit is use to contact the robot arm motors, sensor, alarm and motor pump when microcontroller give the signal.

Content

- This circuit have three relays 250v / 12v 5 amp and two relay 125v / 12 v 1 amp.
- Three relays is to contact two motor for robot arm and one motor pump.
- Another two relays is to contact alarm/buzzer and sensor circuit.
- One regulator transistor 12v to 9v is use to reduced the voltage to 9 v for sensor circuit input power.
