# WiFi-Enabled LED detector tells me when my Dehumidifier is Full!


I created a Wi-Fi-enabled LED Detector using Nordic's nRF7002 Design Kit (DK). Using this box, I can detect when LEDs on appliances, like my lab's dehumidifier, are on. In other words, my non-IoT tool can send me messages over the Internet now! And, because the nRF7002 has a dual-band Wi-Fi antenna, it does so on my 5 GHz network.

I ran into a number of issues with this project, and I expected that. Except for the RF part of the design, which works fine! Links to the design files are available on the [post on the element14 Community](https://community.element14.com/challenges-projects/element14-presents/project-videos/w/documents/46432/using-nordic-s-nrf7002-my-dehumidifier-tells-me-when-it-s-full----episode-650).
