摘要
本文介绍了一种具有无线传输功能的智能气敏传感器系统。该系统将具有ARM7(Advanced RISC Machines 7)内核的LPC2131应用到测量气敏元件阻值及其所处气体浓度的测试电路的测量仪器中,实现了气敏传感器的智能化。另外将无线收发芯片nRF403应用于该系统,实现测量系统所测数据的无线传输,用户可在接收端对系统进行控制。该系统避免了复杂的现场连线,应用灵活,提高了工作效率,降低了工作成本。
A kind of new intelligent gas sensor which has the function of wireless data transmission is introduced. This system is applied LPC2131 with ARMT(Advanced RISC Machines 7) kernel to the testing circuit. Using its powerful data calculation and control capability, a gas sensor testing circuit which can measure the resistance changing of gas sensor and the gas concentration of the environment is designed. This can make the gas sensor being intelligence. In addition, wireless transceiver chip nRF 403 is applied to this system. It can realize the transmission of wireless data which we got from the testing circuit. This system improves the efficiency and reduces costs.
