WEEK 11 FYP SEMESTER 2


Objective

To integrated between temperature sensor circuit and RF system


Activity

The integration between RF system and temperature sensor circuit is by connected to temperature sensors which is LM 35. The RF system is used which is RF module that consists of transmitter module and receiver module. This module is shown below how it look like :

Connection between LM 35 and RF module is output LM 35 is connected to the data input from transmitter module (figure first) and the output data from receiver module (figure second) is connected to input pin out at PIC which is PIC16F867A.

WEEK 10 FYP SEMESTER 2


Objective

To construct and solder temperature sensor circuit.


Activity

This circuit is soldering to testing up whether this circuit function or not. The circuit using PCB printed that create at shop. Below shown how soldering component :

The supply is both share between temperature and motion circuit. Therefore below show how integrated  between two circuit into one supply :

WEEK 9 FYP SEMESTER 2


Objective

To construct,solder and testing PIR module circuit into board.


Activity

This circuit is completed with combine the PIR module sensor, astable 555 timer circuit and 7408 Logic AND Gate. The result is shown below and scenario is when both or one from sensors detect motion, they is no indicator trigger. If both sensor detect motion, so indicator which is buzzer and LED(add on) will trigger :

 

WEEK 8 FYP SEMESTER 2


Objective

To testing and to make two sensors run simultaneously.


Activity

Below show the successful PIR module circuit using one module sensor only :

To solve the problem if using two sensor to detect is by create another 555 timer circuit for second PIR module sensor. To compile both motion sensor into one output is using 7408 Logic AND Gate. This gate is suitable gate to my project cause of the output may indicate if both sensor detect same motion so the buzzer will produce buzzing sound that show the motion is detected. If only one motion detect from both sensor, nothing happen from the indicator.Below shown the 7408 Logic AND Gate :
