In order to detect the amount of light that is needed to decide when to cut-off the circuit and later activate it, this project is done with the help of a sensor called Light Dependent Resistor LDR. The main principle used behind the LDR is that the presence of light causes the resistance of the sensor to go low.

You can modify the circuit by placing LEDs instead of the volt lamp. To know more about it, check out the comments given in the circuit. The circuit is comparatively easy to design, and further modifications can be made according to your choice. Here a simple circuit that can be used to charge batteries is designed and created.

The number of components needed for this circuit is very less and can be easily assembled on a PCB.

A transistor sensor called BC is used to sense the heat produced due to the fire. A preset level can be kept for the transistor. As soon as the temperature rises above the set preset level, the leakage current of the transistor rises, thus driving the other transistors in the circuit. The components needed for the circuit can be obtained easily and the circuit is easy to design. Cutting Cable with Scissors and Arduino :An automatic cable cutter at very lost is designed here.
