Instructables: Hanging Gear Weather Station

In this Instructable, I’m going to be showing you how to build your own hanging gear weather station, which is made from CNC laser-cut MDF parts.

A stepper motor drives each gear and an Arduino takes temperature and humidity measurements using a DHT11 sensor and then moves the stepper motors to display the measured values.

The weather station is supported by two legs and a flat base, making it perfect to stand on a desk, shelf, or side table.

The DHT sensor has a range of 20-95 percent relative humidity and can measure temperature between 0 and 50 degrees Celsius. I’ve designed the gears for the full humidity range and with a negative temperature measurement range so that you can easily use a different sensor if you’d like to place the sensor outside to measure the outdoor temperature.
