A Battery-Powered NFC Tag That Logs Ambient Temperature & Humidity

Tap it with an NFC-enabled phone and you will see timestamped readings appear in a web application. It’s a one-step operation that requires no configuration and no app installation!

I am pleased to be launching the cuplTag crowdfunding campaign here on Crowd Supply. It has taken many design iterations over the course of five years to get the product to this stage. I am now confident it is good enough to share.

I hope you enjoy using cuplTag. If you like the concept, please share our campaign page with your friends!
