Infrared Remote Controlled Devices
- 2. • Introduction • Block Diagram • Components Used • Component Description • Circuit Diagram and Description • Conclusion • Future Possibilities • References
- 3. • The aim of our project is to design a circuit that one can control home or industrial appliances with the help of a remote. • When the Infrared sensor receives the signal, the received signal is matched with the code assigned to respective device and toggles its current state.
- 4. • A TV remote that follows RC5 Protocol is used here. • Here we are switching 7 LED’s and 1 bulb and also controlling the brightness of a bulb. • This circuit can be operated from a distance of about 5-10 meters.
- 6. • 5V regulator LM7805 • Infrared sensor (TSOP1738) • Microcontroller AT89S52 • PIC12F675 • EEPROM • Opto-isolator TRIAC driver • Dimmer IC • TRIAC • 16x2 Alphanumeric LCD
- 7. 5V regulator LM7805 • It is a regulated power supply IC • First two number shows positive voltage & last two number shows magnitude of voltage • Output Current up to 1A 1-Input 2-Gnd 3-Output
- 8. Infrared sensor (TSOP1738) • TSOP module has an inbuilt control circuit for amplifying the coded pulses from the IR transmitter • TSOP1738 is sensitive to 38 KHz 1-Gnd 2-Input 3-Output
- 9. Microcontroller AT89S52 • 8K Bytes of In-System Reprogrammable Flash Memory • 256 x 8-bit Internal RAM • 32 Programmable I/O Lines • Two 16-bit Timer/Counters • Eight Interrupt Sources • Low-power Idle and Power- down Modes • 40-pin DIP
- 10. PIC12F675 • 8-Pin FLASH-Based 8-Bit CMOS Microcontrollers • 6 I/O Pins • Has a 10-bit A/D converter. • Has program inbuilt to decode TV remote signals
- 11. EEPROM 24C16 • Is a kind of non-volatile memory • 1 million erase/write cycles with 40 years data retention • C stands for Standard Version • Stored memory is permanent until it is not electrically erased
- 12. Opto-isolator TRIAC driver MOC3021 • MOC3021 is optically isolated TRIAC driver device • Combination of LED and a DIAC • Pin no. 6 is connected to gate of TRIAC for its triggering • Pin no. 4 with the MT2 of the TRIAC
- 13. Dimmer IC • Dimmer IC is also a programmed microcontroller • Pin 1 is Vcc, Pin 2, 3, 4 is address D0, D1, D2 and Pin 8 is ground pin • We are changing the firing angle of TRIAC
- 14. TRIAC BTA12 • TRIAC is a switching device of Power Electronics works on AC signal having three terminals MT1, MT2 and GATE • For BTA12, BT is TRIAC series, A is insulated type and 12 is 12 amp current in the output • Bidirectional Thyristor, because it conducts in both directions 1-MT1 2-MT2 3-Gate
- 15. 16x2 Alphanumeric LCD • Very compact and light • Easy to interface with microcontroller • In our project we use it in 4-bit mode
- 18. • The remote we use, sends a train of bits (0’s and 1’s) of some fixed length modulated with a 38 KHz infrared signal • The demodulated signal from TSOP sensor is fed to pin no. 2 of IC PIC12F675 • The decoded signal from PIC 12F675 is fed to pin no. 10 (port 3.0) RXD (serial input port) of AT89S52
- 19. • Now microcontroller have a simple program that turns ON switch if OFF and vice-versa • TRIAC and opto-isolators are used for switching of the devices • EEPROM is used to write the current status on LCD
- 21. • For Disabled Persons • In School & Colleges • In Shops • For A Patient • This system reduces human efforts and makes life a bit easy without compromising on the efficiency of appliances. • Using this system one can also save time.
- 22. • This project gives an idea about working of a sensor and decoder circuitry. • This project can be used anywhere either at home or offices. • Thus by this attempt, ON/OFF process of a device was successfully carried out by just using a TV Remote.
- 23. • Due to use of microcontroller the work presented in this project can further be extended for web interfaced control application using Ethernet module like ENC28J60, RTL8019 etc.
