Geometry of Daylight Sensors[edit]

The Solar Angle variable from Daylight Sensors go from 0 degrees at mid-day, to 180 degrees at midnight, and then back to 0 degrees. The value is never negative.

As you can see from the table above, most plants need a minimum of 10 minutes of light, and 5 minutes of darkness. We can split the remaining 5 minutes equally, giving us 12.5 minutes of light and 7.5 minutes of darkness.

Let's do some math...[edit]

  • The planet rotates 360 degrees per day.
  • A day is 20 minutes.

360 degrees / 20 minutes = 18 degrees per minute

  • We need light for 12.5 minutes per day.

18 degrees per minute * 12.5 minutes = 225 degrees

  • We want half the light-budget on either side of mid-day

225 degrees / 2 = 112.5 degrees on either side

Bringing it all together[edit]

What you need:

  • Logic I/O (x2) > Reader and Batch Writer
  • Logic Processor > Compare
  • Logic Memory
  • Kit (Sensor) > Daylight Sensor
  • Place the Daylight Sensor outside, facing up. Direction of data-port doesn't matter.
  • Logic Reader > IN: Daylight Sensor VAR: Solar Angle
  • Logic Memory > Value: 112.5
  • Logic Compare > 1: Logic Reader 2: Logic Memory OUT: Less
  • Logic Batch Writer > IN: Logic Compare OUT TYPE: Grow Light OUT VAR: On

Saving Power[edit]

You can save a bit of power by delaying turning on the light. If you reduce the time with lights to 10.5 minutes, then you can set the Logic Memory to 94.5.
