在汽车快速向智能化迈进的进程中,传感器尤为关键。在这一趋势下,安森美半导体推出世界上首款无源、无需额外单片机控制的智能传感器,基于RFID协议,单芯片集成能量收发功能,可检测温度、湿度、压力和距离,开创了传感器应用的新格局。智能无源传感器的功能模块及工作原理智能无源传感器包括三个功能模块:天线模块,基于Magnus IC的传感器模块,电源、单片机、处理模块,如图1所示。天线模块基于UHF工业标准第二版协议进行无线通信,并收集能量供内部处理单 Sensors are particularly critical in the process of making cars smarter. Under this trend, ON Semiconductor introduced the world’s first smart sensor with no need for additional single-chip control. Based on the RFID protocol, the single-chip integrated energy transceiver can detect temperature, humidity, pressure and distance and create a sensor application The new pattern. Smart Passive Sensor Function Module and Working Principle Smart Passive Sensor consists of three functional modules: antenna module, Magnus IC-based sensor module, power supply, microcontroller, processing module, as shown in Figure 1. The antenna module communicates wirelessly based on the UHF Industry Standard Second Edition protocol and collects energy for internal processing
