Moisture is a problem for most things in storage. How do you know that your storage bin is air tight? How do you know if your desiccant is still working? You could get a hygrometer but that would require your bin to be transparent enough for you to read the device.
This project is perfect for bins that are opaque or too cloudy to read a meter from the outside. I store 3d printer filament in a Pelican case that is solid black. I needed a way to make sure the case was air tight and that the desiccant still worked. This project is also great for when you need to monitor out of sight storages.
This project uses the ESP8266 Wi-Fi module and Cayenne by myDevices. The ESP8266 is inexpensive and easy to use. Cayenne is an IOT service that provides a very nice, intuitive drag and drop dashboard to display data from the ESP8266. Cayenne also monitors your data and provides custom alerts sent via text message to your phone or email.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
