Abstract

Rapid transmission of the coronavirus disease via droplets and particles has led to a global pandemic. Expeditious detection of SARS-Cov-2 RNA in the environment is attainable by using Bio-FET sensors. This work proposes a Bio-FET sensor interface module with IoT implementation to amplify signals from a Bio-FET for SARS-Cov-2 detection and monitoring. The sensor interface module was programmed to read the signals using a micro-controller and process information to determine the presence of SARS-Cov-2. The proposed Bio-FET sensor interface module was also set to transmit data to the Cloud via W-Fi to be stored and displayed on a dashboard. The prototype Bio-FET sensor interface module was simulated in PSpice for signal amplification, and hardware implementation has been done by using low-cost components for data transmission to the Cloud. The hardware consists of an AD620 instrumentation amplifier module, voltage sensor module, Neo-6m GPS sensor module, an OLED display, and an ESP8266-32 bit micro-controller. The results of both the simulation and the hardware implementation are similar. The emulated negative and positive Bio-FET signal outputs were successfully amplified from 15.9mV and 45.8mV to 1.59V and 4.58V, respectively, using an AD620 instrumentation amplifier. The gathered location, time, date, output voltage, and SARS-Cov-2 presence results were successfully stored and displayed on the Cloud dashboard. 
基于物联网的新型冠状病毒监测生物fet传感器接口模块
冠状病毒通过飞沫和颗粒的快速传播已导致全球大流行。利用生物场效应晶体管传感器可以在环境中快速检测SARS-Cov-2 RNA。本工作提出了一种具有物联网实现的Bio-FET传感器接口模块,用于放大来自Bio-FET的信号,用于SARS-Cov-2检测和监测。对传感器接口模块进行编程,使用微控制器读取信号并处理信息,以确定是否存在SARS-Cov-2。拟议的Bio-FET传感器接口模块也被设置为通过wi - fi将数据传输到云端,然后存储并显示在仪表板上。在PSpice中对原型生物场效应晶体管传感器接口模块进行了信号放大仿真,并通过使用低成本组件将数据传输到云端完成了硬件实现。硬件由AD620仪表放大器模块、电压传感器模块、Neo-6m GPS传感器模块、OLED显示屏和ESP8266-32位微控制器组成。仿真结果与硬件实现结果相似。利用AD620仪表放大器成功地将模拟的负、正Bio-FET信号输出分别从15.9mV和45.8mV放大到1.59V和4.58V。收集的位置、时间、日期、输出电压和SARS-Cov-2存在结果已成功存储并显示在Cloud仪表板上。
