The new daylight sensing block, which can tell whether it is being hit by light, has been used to create a passage that only opens in moonlight at midnight, inspired by the Lord of the Rings Mellon passage. Check out the video!
Five Uses For The New Minecraft Daylight Sensor
If a door is opened, allowing light into your base, then a daylight sensor block can trigger a redstone current that will in turn trigger a dispenser or ten full of arrows.
Light / Time Sensitive Doors
See the video above 🙂
If a redstone Not gate is connected to the daylight sensor, the polarity will be reversed and the daylight sensor will emit a redstone charge when it is dark. Here’s a link to a one minute long video that teaches you how to make a redstone inverter, or NOT gate. This will enable you to have a city that never sleeps, with street lights activating at dusk and turning off at dawn.
Rain Sensor / Barometer
The light sensor is sensitive to the cloudy weather that is associated with rain, so you can use a day light sensor to create a rain warning system, which could very well prevent accidental exposure to lightning strikes.
If you’re creating a medieval city, you can create a redstone operated gate that opens in the day time and closes at night, just as was done in the days of yore.
How To Craft A Daylight Sensor
The daylight sensor can be made using three glass blocks, three pieces of nether quartz (another new item) and three wooden slabs, all placed in horizontal lines along the crafting grid.
