XMLSS09S001Remote Control Transmitter

User Manual 1. Sensor Overview The tire pressure sensor consists of the following units: - Tire guard transmitter type which includes an integrated pressure, temperature and acceleration sensor and a RF transmitter. In stationary mode, the pressure and acceleration are measured about every 30 second and emission of RF frames occurs only if pressure variation, higher than a threshold, is detected (leakage detection). When the vehicle starts moving, the Tire Guard transmitter enters the driving mode. Then the wheel unit measures and transmits data every 60 seconds. If, during any measurement period in driving mode, the pressure leakage is detected (difference compared to the last transmitted pressure value), a alarm signal will occur taking in account the latest pressure value emitted as reference value. If the pressure continues changing, an additional transmission will be sent. 2. Technical Description Carrier frequency: 315 MHz Number of channels: 1 Method of frequency generation: PLL Type of modulation: ASK Rated Output Power: 67.63 dB(μV/m) Antenna: External (Valve antenna) Voltage supply: Lithium battery 3V Voltage supply range : 2.1V up to 3.3V 3.
