Dual Control of Electrical Device through Computer Keyboard and Hardware Keyboard
This project aims to use the computer keyboard as a dual controller for switching Electrical Devices like Fan, Tube lights, Televisions etc. Also we can monitor the Current for the devices. This project also has the provision for setting the current limit also, and the loads will get tripped if the current exceeds the limit. The Actions Done can also be Announced by using the computer Multimedia Speaker for eg if a motor is switched on/off This is achieved with the use of advanced Transducers and Relays. The is e o/p of the sensors is conditioned and fed into the centralized computer by means of a PIC Microcontroller using RS232 Interface. The Features included are
On/Off provision for Devices:
Using computer keyboard we can able to Switch on or switch off the house hold devices like TV, Fan etc by using the computer Keyboard Keys. The indications are given in the computer screen itself ie., Status of the devices (On or Off).
Temperature based Action:
By using thermistors we can able to identify the temperature fo the devices and we can accordingly trip the devices.
