There are a number of different temperature-monitoring solutions on the market. I’ve listed a few companies below, with articles we’ve run regarding their sensors. Some solutions use active (battery-powered) RFID, while others use battery-assisted (a battery powering the sensor, but not the tag) or passive (no battery) RFID.
The issues are what read range you need, and—once the tag senses a rise in temperature and communicates such to the reader a few feet or yards away—how you can get that information into the hands of someone who can then act on it. A good systems integrator could recommend the right solution based on your particular environment, but there aren’t many that have experience with these types of specialized tags. The manufacturers might be the best place to start.
