Project Hardware Clasiffication

Buzzer

Buzzer

Buzzer used in the project is 5V buzzer. It is direct connected to PIC. Whenever invalid entry detected the buzzer will turn on. Else it remains off.

Solar Panel

Solar Panel

 5W, 12VDC Solar Panel 

(Vmax: 17.4VDC,Imax: 0.29A)

Vibration Sensor

Vibration Sensor

Vibration sensor for the system is pulled to high. So when no vibration detected the sensor gives signal 0 (0V). Else it gives signal 1 (+5V).

Voltage Regulator   

LM7805

LM7805 is used to regulate voltage in the system and output 5V DC (max output current: 1000mA). It supports input voltage from 7V DC to 18V DC. If the input voltage is over, the LM7805 will burn or auto shutdown due to overheat. 

  

Output LED indicator

LED

LED use 5V and 5mA to operate. And through LED the current status of the system can be known. A 1KR resistor is connected series with the LED to limit the current pass through LED is 5mA. This is calculated using V=IR. Where V=5VDC, R=1KR.

 

 

Push button Switch

• S1-Active-low push button. Determine as ON/OFF switch.
