Our second video moved us into some territory where we had to study a bit and pick up some new skills. We'd never used Arduinos before and had only ever done ultra basic electronics, so it was a great experience to learn how easy it is to make this stuff.

After a few months of tinkering and practicing, we came up with a design for this humidity sensor that would live in our shop. The purpose of it was to alert us to big swings in the Texas humidity so if we had an important woodworking project going, we could move it in the house or take other steps to not have it get all warped and messed up from the humid air.

It changes color depending on the humidity, so we could just open the door to the garage and peek in to see how things were doing. If it gets towards blue/purple light, it was super humid and time to move some stuff around.

It has a dovetailed walnut case and uses an Arduino Uno with some rad parts from Adafruit. Came out super cool. Give it a look!

How to Make an Arduino Humidity Sensor

Jay & Jaimie make an Arduino humidity and temperature sensor for the work shop! Woodworking, 3D Printing, Arduino/Electronics, this project has a lot of great stuff!

This DIY project showcases a bit of woodworking with walnut dovetails and beginner electronics using an Arduino Uno and some excellent parts from Adafruit. We're new to making videos so we'd love to hear your feedback. Leave us a comment! We live in Central Texas where we get massive swings in Humidity and Temperature in the Spring, which can be disastrous for certain woodworking projects. This cool project helps alert us when the humidity is changing or starts to get high so we can take precautions like moving our wood projects into the house, or not doing any milling during the high humidity weather. It also looks awesome and has our sweet logo.
