People who work in different types of industries such as lathe and grinding industries tend to meet with accidents which are due to the manual or machinery faults and thus causing death. This prototype will play a major role in saving the life of the worker. A LDR(Light Dependent Resistor) is used in this prototype which is the important part of the circuit and a 555 IC is used which is the brain of the circuit. Light Dependent Resistor which senses the light and if there is no light incident on it, it triggers the IC and an LED glows which is attached to the circuit. In the place of LED, a buzzer or speaker can be used as detector alarm. The concept is based on the work of a LDR. This prototype is designed in a way that LDR senses the light and if there is no light, the sensor triggers the IC and the machine stops even before the worker gets stuck into the machine and the alarm rings till the area is examined and the worker can be saved from this
