How a twilight sensor works

There are two types of twilight sensor: electric and electromechanical. The twilight sensor is an accessory widely used in the garden thanks to its operating system: it activates before sunset and deactivates before sunrise. On the back is installed a small photosensitive panel which manages to detect the percentage of brightness present in the environment in which the sensor is installed and therefore to activate (or deactivate) the power circuit of the light cell. Some models of twilight sensor can also be programmed to turn on and off according to your needs. The latest models also allow weekly programming in addition to the daily one. This prolongs the life and efficiency of the sensor and prevents it from being turned on during the day in the presence of atmospheric conditions that reduce the real brightness.


External twilight sensor

The external twilight sensor is a product readily available on the market and is present in various shapes and sizes. The most commonly used are 220 volt ones powered by current and 12 volt batteries. The first type of external twilight sensor allows you to create extremely suggestive illuminated points inside your garden. By making the passage of the electric cables, flowers and plants will also shine during the night. The 12 volt external twilight sensor is suitable for small gardens, because the brightness is much less intense. Operation takes place thanks to the external batteries which must be checked periodically (especially in summer) to prevent the escape of corrosive acids that damage the sensor. Both types of external twilight sensor can be programmed to allow greater energy savings.
