This is the circuit connection required for the Automatic light controlling system using Bolt IoT.

This is a project that will completely automate your lighting needs. This system uses a Light Dependent Resistor (LDR) whose resistance changes according to the light intensity of the surroundings. The data from the LDR is collected and sent to the Bolt Cloud by the Bolt Wifi Module. The data is then analysed and the light is turned on if the value received is below the preset threshold. It will also send an SMS to the registered phone number if such an incident occurs.

The system will automatically turn off the light when the light intensity increases above the threshold and an SMS regarding the same will also be sent.

The bonus feature of this project is that this system is that it can detect any anomaly in the light intensity of the surroundings. The system is designed in such a way that if the light intensity in the surroundings increases or decreases suddenly, the system will detect it as an anomaly and send an SMS regarding the same.
