Abstract

The system consists of an energetically and informationally autonomous node, which collects data about atmospheric pressure, temperature, humidity, and gas concentrations for carbon monoxide and methane and sends this data to a dedicated receiver that will store it and make it available for visualization. Communication is realized through the IEEE 802.15.1 standard, via Bluetooth. The node consists of an Arduino Nano which uses an Atmega328P microcontroller, a sensor BMP180 module, two modules for detecting gases - MQ-7 for carbon monoxide and MQ-4 for methane, an HR202 module for humidity and an HC-05 Bluetooth module. On the receiving end, a mobile application for Android phones developed using Android Studio and Java is used. The data can be then visualized as graphs using a Python script. The system can be used to monitor the temperature, humidity, and atmospheric pressure of a room as well as add a layer of safety with alerts when the danger threshold for methane or CO is passed.

用于室内环境监测的蓝牙传感器模块

该系统由一个能量和信息自主的节点组成，该节点收集有关大气压力、温度、湿度以及一氧化碳和甲烷气体浓度的数据，并将这些数据发送到一个专用接收器，该接收器将存储这些数据并使其可用于可视化。通信通过IEEE 802.15.1标准，通过蓝牙实现。该节点由Arduino Nano(使用Atmega328P微控制器)，传感器BMP180模块，两个气体检测模块(MQ-7用于一氧化碳，MQ-4用于甲烷)，HR202模块用于湿度和HC-05蓝牙模块组成。接收端使用Android Studio和Java开发的Android手机移动应用程序。然后可以使用Python脚本将数据可视化为图形。该系统可用于监测房间的温度、湿度和大气压，并在甲烷或一氧化碳的危险阈值超过时增加一层安全警报。
