Safety sensors are devices that detect potential hazards or unsafe conditions in a workplace, and trigger an alarm or shutdown mechanism to prevent accidents. These sensors can be used for various purposes such as detecting excessive heat, smoke, gas leaks, unauthorized entry, or the presence of dangerous gases or chemicals. They are commonly found in industries where there is a risk of fire, explosion, or other hazardous conditions that could harm workers or damage equipment. By monitoring these safety sensors and responding to their signals, employers can take proactive measures to prevent accidents and maintain a safe work environment for their employees.
