It can be difficult to determine the pressure in a ball even with a pressure gauge. Pressure gauges are leaky and a bit difficult to use effectively. This no-battery sensor is powered and read by a smartphone to provide pressure measurements for the entire life of the ball.
To use this item with tubeless bike tires, just mount to the inner wall of the tire and read from the outside (do not use tire sealant in the tire). To use with other inflatables, puncture a small hole, and align the hole in the pressure sensor IC with the hole in the inflatable. This model is not usable for pressures over 50 psi.
Glue a patch over the entire RFID patch and it should be measuring pressure. We will warn you it is not necessarily easy to get a good seal on the patch, especially on balls. A future flexible design is in the works, and that may improve sealing, but it will still be difficult to get a good seal.
This tag is operable with Android phones. Android app will be posted to the Google Play store when the product is back in stock.
- Sensor size: 25 mm x 25 mm
- Read distance: ~25 mm with Android smartphones
- Battery life: No battery. Powered wirelessly by reader
