Hello Brandon, thanks for reaching out. The Flow Through Tire Sensors for TireMinder TPMS # TM66FR do not work by themselves. You will need both a signal booster and monitor in order to use the sensors. For example, the TireMinder A1AS TPMS # TM76FR comes with everything you need to use the sensors and monitor your tires with your smartphone. Keep in mind that if you intend to use the app, you do still need to have the monitor in operation within 10 feet of your smart device. This ensures a solid connection between the sensors and your phone. The signal booster is also a requirement.

The video I linked below goes over the TPMS in detail. Feel free to comment below if you have any other questions.

For a tire pressure monitoring system that has 4 flow thru sensors we have the TireMinder A1AS TPMS for RVs and Trailers #TM76FR which would work really well. These can be left on during storage without issue as well.
