Wireless Temperature Sensor Measures Tyre Temperature via Infra Red (IR)

Believed to be the only sensor available that can perform wireless infrared (IR) tyre temperature measurements, the IRN8WS4 transmits data to a generic master receiver in 868, 902 or 920-MHz frequencies. This, says the Texense Renvale Group, gives users the option to pick the best one frequency, depending on the location.
