I am back ones again to share with you my simple but useful project and step by step descriptive video to show you, how you can auto turn on the room Light when some come inside the room. It’s only work when someone moving in the room and after few second light will turn off automatically. To detect the motion I have used PIR Motion Sensor and program the arduino board to read the sensor signal and turn on the light for few second.
To make this prototype I am using:- Arduino UNO PIR Motion Sensor Jumper wire Breadboard

Till now, I have received hundreds of suggestions and requests about this Library and I have always told them that its under designing process and I will post it real soon. So finally the wait is over and we have our new GSM Library for Proteus, ready to download and simulate in Proteus. Using this GSM library for Proteus, now you can easily simulate your GSM module in Proteus and can test your code.
