Low-speed EV TPMS — a phone check, not another screen
Low-speed electric vehicles, neighbourhood EVs and light electric utility vehicles are built to a price and rarely get a factory tyre-pressure system. A sensor that reports to a phone costs less than a display and needs no installation visit.
What the operator actually needs
Not a dashboard. These vehicles are used for short trips and are checked by whoever drives them. What matters is that a soft tyre is noticed before it becomes a destroyed tyre and a stranded vehicle.
What the sensor is
| Item | Value |
|---|---|
| Wireless | Bluetooth 5.1, 2.4 GHz — no receiver required; the phone is the reader |
| Pressure range | 0–500 kPa gauge (0–600 kPa absolute) |
| Accuracy | ±2 kPa |
| Battery | Replaceable CR1632, average service life about 1.5 years, no re-pairing after a change |
| Working / storage temperature | −20 to +80 °C / −40 to +85 °C |
| Sealing | IP67 |
| Size | Diameter 21 mm × 16 mm high |
A receiver can be built to order if the data has to reach your controller or a display instead of a phone — serial (UART) or CAN output. That is a different configuration, not a different sensor.
OEM and aftermarket
- Vehicle builders: specify the sensor as a line item; your app or ours; your box.
- Fleet operators: retrofit what you already run, without touching the wiring loom.
- Distributors: a kit that a workshop can install with a phone and no training day.
Honest limits
The standard range covers passenger-vehicle pressures. Higher-pressure applications need a different sensor — say the working pressure in the first message and we will tell you whether it is inside the range or not.
