FYP 2 : WEEK 9

Title of activity

- Construct the LDR sensor circuit

Objective

- This sensor circuit is use to get the sensor function.

Content

- The sensor circuit is use one relay using to contact the circuit when flame is detect by sensor.
- One veriable resistor is use to adjust the sensitivity of sensor to the flame.
- This circuit is supply by 9 V power from main circuit.
- After construct, I test the circuit and it work.
- The minimum for sensitivity sensor is 5 cm from the flame and the maximum for sensitivity sensor detect is 3 meters.
