After complete soldering process, the PIC board is tested on its vibration sensor, relay and LED to make sure it's well-function. The test is conducted using PIC C compiler software. Before the PIC board is test, coding must be done. The test is conducted to test:
i. light led
ii. blinking led
iii. vibrator sensor and
iv. display on LCD by activate relay.
The Result:
i. light led
ii. blinking led
iii. vibrator sensor and
iv. display on LCD by activate relay.
The Result:
Then, we were given new task. Encik Mazran ask us to study AP command. Below are the flow:
GSM modem is specialized type of modem that operates over
subscription based wireless networks which is similar to a mobile phone. A GSM
modem accepts a SIM card, and basically acts like a mobile phone for the computer.
Traditional modem is attached to computers for ‘dial-up’ to connect with other
computer systems. A GSM modem operates in a similar fashion, except that it
sends and receives data through radio waves rather than a telephone line.
Besides the dial-up connection, GSM modem can also be used for sending and receiving SMS which is also one of the key features of GSM modem. In this issue, we discuss on how to set up a simple home automation where we can control the fan and monitor the alarm status by using SMS. All the examples given are based on the MOD 9001D GSM Modem available from Cytron Technologies.Some of the features of this GSM Modem are as follow:
i. RS-232 Interface
ii. Support PDU and Text mode for SMS
iii. Tri-Band: GSM900, GSM1800 and GSM1900
iv. Support TCP/IP
v. Support GPRS class 10
vi. Support standard extended open AT commands
vii. Accept supply voltage from 5 to 12V
