However, there are a lot more applications besides consumer convenience. The security application of detecting infiltration into containers or rooms is crucial. Knowing when a shipping container has been opened might be crucial when transporting expensive cargo since it helps with the resolution of cases concerning product loss. Every time the container is opened, a simple photo-resistor might be used to record the event, allowing it to be determined when robbers raided the container or if the sender was lying when they said it had been robbed.
Many other products are sensitive to light, but only Light Sensors can provide accurate information about light. For instance, exposure to sunshine can harm older pieces of art, paintings, and photographs on paper, so it's crucial to know how much light they receive. A light sensor could be used to check that a piece of artwork wasn't exposed to the sun for an excessive amount of time before delivery.
