OI Brick TPMS
The OI Brick TPMS is an extensor that, mounted on a standard tyre valve, measures the tyre’s air pressure, temperature and the battery voltage level and transmits this data through the radio interface (434 MHz license-free ISM band). This proprietary Micro.sp® technology is based on short pulses transmitted using Pulse Position Modulation (PPM), which guarantees high RF peak power, as required for radio link reliability, but with very low average power and consequently drawing little current.
Powered by a standard CR1225 lithium battery, it guarantees a lifetime of at least 3.5 years.
The OI Brick TPMS enables the delivery of innovative applications through its compact design, unique wireless protocol, and ultra-low power communication system.
