Detection of Carbon Dioxide and Humidity

Abstract

The general purpose of a detection of carbon dioxide and humidity system is threefold, to design and develop sensory instrumentation system by improving the accuracy of monitoring and measuring the carbon dioxide gas, humidity and temperature, to display parameters of carbon dioxide (PPM), temperature (degree Celsius) and humidity (percentage) through ThingSpeak platform Internet of Things (IoT) and to produce a low-cost instrumentation system (prototype) which promote the Internet of Things (IoT) platform via Arduino IDE. The project focused on the monitoring the real-time measurement readings of the humidity, temperature and carbon dioxide gas level in each hospital ward, especially during the haze atmospheric phenomenon. The system uses only two sensors and one ESP8266 module to collect data information and display real-time information through Thing Speak application as an Internet of Things (IoT) platform. The Internet of Things (IoT) system was found to be one of the best methods to be applied especially in the hospital environment to ensure humidity, temperature, and carbon dioxide gas can be closely monitored from time to time via mobile gadget communication. The foremost concern of the field study is the detection of carbon dioxide and humidity with IoT system as a new development platform which enables to collect and exchange data, tested and applied related analysis technique and design the IoT systems. The research of this project is to evaluate the IoT system configuration as a value added to continuously monitor real-time measurement in the hospital environment. The sensors sensitivity and accuracy are experimented in detecting three parameters such as temperature, humidity, and carbon dioxide gas. This resulted to improve accuracy percentage and economic benefit in terms of low-cost prototype development. These research studies recommend high accuracy sensors through the Internet of Things (IoT) application as a product development for monitoring carbon dioxide gas via ThingSpeak using hospital network platform.
