Tire Pressure Sensor: Description and Operation

Description




1. Mode
(1) Configuration State
A. All sensors should be in the Low Line state.
B. In Low Line configuration, sensor transmissions occur every 1 minute (nominal) and pressure is measured every 4 seconds.
(2) Normal Delayed Auto State
A. In this state, the sensor will transmit for approx. 12 minutes before automatically entering storage state.
(3) Storage Auto State
A. This state is a Low quiescent current state.
B. In this state;
1) Ignition off.
2) The sensor does not measure pressure / temperature / battery level.
(4) Alert State
A. The sensor automatically enters this state if the measured temperature exceeds 110°C and over temperature shutdown is likely.
B. In this state, pressure is measured every 4 seconds and RF data transmitted every 4 seconds.
C. The state lasts for 1 minute if it is pressure triggered.
