Minneapolis-based Rover Development just sent details on their latest product, the PSIcle sensor, which uses a patent-pending, lightweight NFC-based pressure sensor to measure and display tire pressure using a smartphone app. It weighs less than five grams, doesn’t have any battery to charge or replace, and threads into your existing Presta valve.
The PSIcle sensor is compatible with tubeless and tubed setups and is available in two models: a low-pressure sensor that measures 0-40 PSI and a high-pressure sensor that measures 0-400 PSI. They claim the sensors are accurate to +/- 0.06 PSI and +/- 0.7 PSI, respectively. Tire pressure measurements are taken by holding your smartphone within an inch of the sensor, which will automatically launch the app and display real-time pressure readings. The video below demonstrates the product in use:
By housing the sensor outside of the tube, the PSIcle team has taken a different (and seemingly more universal) approach than the team behind Tubolito’s PSENS, who also launched an app-based pressure measurement solution just last month, but with the NFC chip integrated the tube itself. The cost for a set of PSIcle sensors purchased via Kickstarter is $52 for early birds, with an estimated delivery time of September 2021, or $56 after that, with an expected delivery of November 2021. When the campaign is finished, sensors will be available for purchase via the Rover Development website.
You can learn more or back the PSIcle sensor over on Kickstarter.
