Automatic Streetlight On/Off with SMS Controlling and Failure Detection with Indication
The aim of this project is to operate the lights using cell phone. Cell phones use GSM technology. The microcontroller plays the key role in this project. The GSM modem will be interfaced to the microcontroller which continuously receives the messages from the user cell phone and passes the same to the microcontroller.
The GSM modem will be interfaced to the microcontroller section through serial port interface. If the user wants to operate the lights, he can just send a predefined message to the GSM modem that is interfaced to the controller section. The controller section will have the switch controls of the devices. All the lights which are to be controlled will be connected to the controlling device i.e., to the microcontroller section. The microcontroller in return, sends a message to the mobile number about the status of all the lights.
The user has to send a predefined SMS to the modem and the modem will intimate the controller about the received message and the controller will act in accordance with the received message such as switching on/off any light.
