What to know

  • Day Sensors and Rain Sensors work through a Logic Block to automatically control powered devices.
  • The power source must connect to the Logic Block before connecting the sensor.
  • Using the inverted setting allows devices to switch on or off depending on day, night, or rain conditions.
  • This setup helps conserve battery power and reduce unnecessary energy consumption.

If you’re building an efficient base in Solarpunk, Day Sensors and Rain Sensors are extremely useful automation tools. They allow your lights, machines, and other powered devices to react automatically to environmental conditions without requiring manual switches. With a simple Logic Block setup, you can make lights turn on at night, shut down equipment during the day, or activate systems only when it’s raining.

Quick overview

Day SensorDetects whether it is day or night
Rain SensorDetects active rainfall
Battery/WindmillProvides power to the system
Controlled DeviceLights, machines, pumps, or other powered objects
Inverted ModeReverses the sensor’s output behavior

How Day Sensors and Rain Sensors work

Sensors in Solarpunk do not directly power devices. Instead, they send a signal to a Logic Block, which determines whether power should be passed to the connected device.

A Day Sensor checks the current time of day and can trigger actions when daylight or nighttime conditions are met. A Rain Sensor functions similarly but responds to weather conditions instead.

Because both sensors use the same wiring setup, you can easily swap one sensor for another depending on your automation needs.

Required components

Before beginning, make sure you have:

ItemRequired
Power Source (Battery, Windmill, etc.)Yes
Logic BlockYes
Day Sensor or Rain SensorYes
Device to ControlYes
CablesYes

How to connect a Day or Rain Sensor

Step #1 – Leave the system unpowered initially

Place your Logic Block and Day Sensor first. Avoid connecting any power sources while arranging the setup to make wiring easier.

Step #2 – Connect the power source

Run a cable from your battery, windmill, or other power generator into the left-side input port of the Logic Block.

This provides the Logic Block with the power it will distribute when conditions are met.

Step #3 – Connect the Day Sensor

Attach a cable from the side port of the Logic Block to the Day Sensor.

The sensor now sends day/night information to the Logic Block.

Step #4 – Connect your device

Run a cable from the output side of the Logic Block to the device you want to automate.

Common examples include:

  • Base lights
  • Workshop machinery
  • Decorative lighting
  • Automated systems

Step #5 – Test the setup

Once everything is connected, wait for the appropriate time of day or adjust the Logic Block settings to verify that the device responds correctly.

Examples include:

DeviceRain Sensor Use
LightsTurn on during storms
Decorative EffectsActivate when raining
Specialized MachinesRun only during rain
Custom Automation CircuitsWeather-based triggers

Understanding inverted mode

The most important setting inside the Logic Block is Inverted Mode.

Normally, a Day Sensor will activate outputs during the conditions it detects. When inverted mode is enabled, the behavior is reversed.

Normal Day SensorActive during the day
Inverted Day SensorActive during the night
Normal Rain SensorActive when raining
Inverted Rain SensorActive when not raining

A common use case is automatic lighting. By enabling inversion, your lights can remain off during daylight hours and automatically switch on at night, helping conserve battery power.

Sensor indicator colors explained

While configuring sensors and logic systems, you’ll notice different color indicators.

ColorMeaning
OrangeDay-related state
BlueNight-related state

These visual indicators make troubleshooting much easier when testing your automation network.

You can create several useful systems using sensors and logic blocks:

AutomationSensor Type
Automatic nighttime lightsDay Sensor (Inverted)
Daytime machinery shutdownDay Sensor
Rain-activated decorationsRain Sensor
Weather-responsive production systemsRain Sensor
Energy-saving workshop setupDay Sensor + Logic Block
Practical automation ideas

By combining sensors with Logic Blocks, you can build a highly efficient base that automatically reacts to changing environmental conditions without any manual input.


Day Sensors and Rain Sensors are among the simplest automation tools available in Solarpunk. Connect a power source to the Logic Block, attach the sensor to the side input, connect your device to the output, and configure inversion if needed. Once set up, your base can automatically respond to daylight cycles or weather conditions while reducing unnecessary power consumption.
