All these process is shown step by step in the below video on youtube.Comment if you have any queries.:
VSPE (Virtual Serial Port Emulator) is a software which provides us the utility to access multiple com ports on the same PC. We can create new serial ports virtually and can connect them as we want. For example I can create 2 serial COM ports and if I pair them then they will be connected with each other. So that I can run two applications
This device can enable you to control your home appliances by just an SMS message. You can also monitor some data like temperature, gas leakage, door status etc. I am using a PIC microcontroller PIC16f887 for this purpose. I written the code in Mplab X IDE and XC8 compiler. Here for demo I have attached a gas, light, door, temperature sensor, Rain sensor. LM35 is used as temperature sensor.
SIM900 GSM modem:
I am decoding the incoming SMS from SIM900 GSM modem. GSM/GPRS Modem-RS232 is built with Dual Band GSM/GPRS engine- SIM900A, works on frequencies 900/ 1800 MHz. The Modem is coming with RS232 interface, which Continue reading
This system can provide all data like temperature, gas , door status of your home on PC screen. All data of parameters like temperature etc are stored in database and can generate Excel file so that you can view data of any day in history you want. This system is very useful in modern houses. Here for demo i am taking 2 sensors: Gas Sensor and a Temperature sensor LM35. The heart of the system is PIC16F887 microcontroller. It monitors both our digital Continue reading
Generally we set log in screens in our applications through which we can enter the details and get access. But some times we fear that if the password and id are lost or stolen then unauthorized user will access the system. Hence here i am suggesting a new idea to improve security. I am adding the hardware level security. I am using Continue reading
