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
This system is ideal for companies which have many manufacturing units.. The system mainly works to help the manufacturing unit to get data of current product quantity and to process this data. In this whole article I am taking example of a company which manufactures pipes. So here product1, product2, product3 … in this article can be circular pipe, triangular pipes, square pipes etc… Many types of pipes.
Conventionally, the company’s manufacturing plants use the product counters to count their product quantity manufactured. Normally these types of systems are equipped with 7-segment displays. Hence whenever Continue reading
