Wireless tire sensor and emitter unit
A microelectronic product which needs to be installed within the tire. The sensor chip uses wireless RF technology to
transmit real-time pressure and temperature values of the tire to the wireless receiver and display unit
Wireless receiver and display unit
A microelectronic product which contains a signal receiving chip, a computational chip, a display device and a warning
speaker
High tire temperature warning
When the tire temperature becomes higher than this warning value (its factory default value is 80º C), this system will
generate visual and audio warnings to alert the driver
High tire pressure warning
When the tire pressure becomes lower than this warning value (its factory default value is 50 psi), this system will generate
visual and audio warnings to alert the driver
Low tire pressure warning
When the tire pressure becomes lower than this warning value (its factory default value is 26 psi), this system will generate
visual and audio warnings to alert the driver
Circumstantial temperature
during tire inflation
It is recommended that the tire can be inflated in a service center under a circumstantial temperature of 25º C
