This paper presents a system for remote monitoring of turbidity data that can detect light intensity and temperature using a microcontroller and the Internet of Things. The system comprises a light dependent resistor and infrared temperature sensor interfaced with an ESP-12E microcontroller, a programmable data acquisition platform; together these enable remote real-time monitoring of turbidity data applicable to chemical education. This system will allow educators and students to monitor chemical experiments in real-time through a web browser. Changes in turbidity and signal processing associated with a light dependent resistor are stored locally on the microcontroller and transmitted wirelessly via a WiFi-based connection to a cloud-based server. The light intensity signals are displayed on the system through an organic light-emitting diode and subsequently uploaded to a cloud-based server. A web-based signal processing MATLAB program plots the uploaded signals available as real-time streams to authorized subscribers over standard browsers.

具有成本效益的无线微控制器，用于开源化学设备的Internet连接

本文提出了一种用于浊度数据远程监控的系统，该系统可以使用微控制器和物联网来检测光强度和温度。该系统包括一个光敏电阻和一个与ESP-12E微控制器接口的红外温度传感器，一个可编程数据采集平台；这些都可以对适用于化学教育的浊度数据进行远程实时监控。该系统将使教育者和学生可以通过网络浏览器实时监控化学实验。与光敏电阻相关的浊度变化和信号处理变化被本地存储在微控制器中，并通过基于WiFi的连接无线传输到基于云的服务器。光强度信号通过有机发光二极管显示在系统上，然后上传到基于云的服务器。一个基于Web的信号处理MATLAB程序绘制通过标准浏览器以实时流形式提供给授权订户的上传信号。
