Presentation on home automation system
- 1. PRESENTATION ON “EMBEDDED SYSTEMS USING 8051 MICROCONTROLLER”
- 2. • The embedded system is a combination of computer hardware, software additional electrical & mechanical parts • A computer is used in such devices primarily as a means to simplify the system design and to provide flexibility. • Embedded systems employ the use of a RTOS (Real-Time Operating System). Introduction to embedded systems
- 4. Microcontroller RAM ROM I/O Port Timer Serial COM Port CPU • A smaller computer. • On-chip RAM, ROM, I/O ports... • Example:- Motorola’s 6811, Intel’s 8051 and PIC 16X A single chip Microcontroller
- 5. The 8051 Microcontroller : • The 8051 is the first microcontroller of the MCS-51 family introduced by Intel Corporation at the end of the 1970’s. • The 8051 family characteristics: ○ The 8051 family characteristics: ○ 4K Bytes ROM ○ 128 Bytes RAM ○ two timer/counters (16 bit) ○ A serial port ○ 32 input/output port
- 7. HOME AUTOMATION USING 8051 MICROCONTROLLER Home automation (also known as domotics) refers to the automatic and electronic control of household features, activity, and appliances. Various control systems are utilized in this residential extension of building automation. Some components of an automated home may include the centralized control of security locks on doors and gates, appliances, windows, lighting, surveillance cameras and HVAC systems
- 8. Keil µVision IDE The µVision IDE from Keil combines project management, make facilities, source code editing, program debugging, and complete simulation in one powerful environment. The µVision development platform is easy-to-use and helping you quickly create embedded programs that work. The µVision editor and debugger are integrated in a single application that provides a seamless embedded project development environment.
- 9. The power supply circuit comprises of four basic parts: The transformer steps down the 220 V a/c. into 12 V a/c. The transformer work on the principle of magnetic induction, where two coils: primary and secondary are wound around an iron core. TRANSFORMER BRIDGE RECTIFIER SHUNT CAPACITOR VOLTAGE REGULATOR VOLTAGE REGULATOR VOLTAGE REGULATOR Powersupplymodule
- 10. HOW WE MADE OUR PROJECT HARDWARE USED— 1.Pcb board 2.Lcd display, ic mounter 3.capacitors,resistors,diodes led 4. 8051 microcontroller, crystal oscillator 5. Centre tap transformer , relays, transistors 6. Bulb holders and ac switches 7. Bluetooth module,15w bulbs Jumper wires and single strand wires and a andriod phone with buetooth app
- 11. IMAGES OF MATERIALS USED
- 13. CONTINUE After making of voltage regulated power supply we joined lcd and ic mounter on pcb board. Then crystal oscillator is mounted on pcb with capacitor and resistance for reset pin of ic . Three relays are mounted on pcb in respective association with transistor, resistors. Buetooth module is mounted on pcb. Finally 8051 is programmed with one program that interfaces lcd ,bluetooth module simultaneously. Holders and switch is joined at respective positions.
