Design of Building Wireless Telemetry System for Temperature and Humidity Monitoring in Multi-Space Using DHT11 Sensors

Introduction

Human comfort is greatly influenced by the temperature and humidity that surrounds us. The daily activities of most people take place indoors, making it essential to maintain a comfortable room temperature. Certain spaces, such as server rooms, drug storage rooms, hospital rooms, clinics, laboratories, and greenhouses, require routine temperature and humidity supervision. The current tradition of direct monitoring involves operators entering the room and reading manual measuring instruments, which can be time-consuming and potentially risky if access to the space is limited.

To overcome this problem, a wireless telemetry system has been designed to monitor web-based temperature and humidity. This system allows users to monitor any location with an internet connection, making it a suitable solution for various rooms. The design is particularly effective for multi-space monitoring, increasing the efficiency and accuracy of supervision.

The Technology Used

This system is supported by the use of Nodemcu ESP8266 and DHT11 sensors, which have been tested based on the specifications that exist in the datasheet. The Nodemcu ESP8266 functions as a Wi-Fi module, enabling it to send measurement data to the server regularly. Meanwhile, the DHT11 sensor is responsible for measuring temperature and humidity with high accuracy.

Temperature Testing and Accuracy

Temperature testing was carried out at reference points of 29 °C, 27 °C, and 25 °C, and the measurement results of the tool were compared with standard measuring devices. The results show that the accuracy and precision values of the two devices, namely tool 1 and tool 2, reach an average of 98%. The resulting data can be accepted by the server at a 10-second interval, allowing the information presented to remain the latest and relevant.

Web Application Features

The web application built for this system offers a variety of practical features. This application is able to display the results of temperature and humidity measurements in real-time, enabling users to easily monitor conditions in various rooms. The data is displayed in various formats, including graphics and maps/room plans, which facilitate the analysis of overall environmental conditions.

Simplicity in Use

The simplicity of the application makes it easy for facility managers, especially in an environment that requires strict supervision. With online access through a web browser, users no longer need to be in a place to check the condition of the room. This saves time and resources, and reduces the risk of human error.

Benefits of the System

The wireless telemetry system for temperature and humidity monitoring is not only efficient in terms of measurement but also provides ease of access and better data analysis. With high accuracy and good data speed, this system is ready to be used for various applications, ranging from drug storage spaces to research laboratories. The application of this system is expected to increase the control and supervision of temperature and humidity, thus creating a comfortable and safe space for its inhabitants.

Conclusion

In conclusion, the design of the building wireless telemetry system for temperature and humidity monitoring in multi-space using DHT11 sensors is a significant innovation in the field of environmental monitoring. The system offers a range of benefits, including ease of use, high accuracy, and good data speed. With its ability to monitor multiple spaces simultaneously, this system is an ideal solution for various applications, including drug storage spaces, research laboratories, and hospital rooms. The application of this system is expected to create a comfortable and safe space for its inhabitants, while also increasing the control and supervision of temperature and humidity.
