Humidity Monitoring

Low-cost electronics developed on easy-to-use prototyping platforms, such as Arduino, are becoming increasingly popular in various fields of science. This article presents an open-source and low-cost eight-channel data-logging system for temperature and humidity monitoring based on DHT22 (AM2302) sensors, named HIGROTERM. The system was designed to solve real needs of the Laboratory of Material Testing of the Department of Civil and Environmental Engineering at the University of Brasília. The system design, functionalities, hardware components, source code, bill of materials, assemblage and enclosure are thoroughly described to enable complete reproduction by the interested reader. The terminologies and instructions presented were simplified as much as possible to make it accessible to the greatest extent to researchers from different areas, especially those without electronics background. The data-acquisition system has an estimated total cost of USD 96.00, or USD 136.00 if eight sensor nodes are included, with a considerable margin for cost reduction. The authors expect that the HIGROTERM system may both be a valuable low-cost and customizable tool for the readers, as well a source of innovation and interest in low-cost electronics for real problem-solving in various fields of science.

A temperature and humidity monitoring system is to check and show the climaticvariances of the hospital’s ambience continuously as well as communicate with the professional responsible for obtaining this type of information. The study proposes a low-cost system that read both temperature and humidity through a capacitive sensor with an accuracy of ±2% relative humidity (max ±5%) and temperature precision < ±0.5 o Celsius for monitoring hospital departments such as Central Sterile Supply Department, Transfusion Agency and Surgical Center. The microcontroller receives the data from the sensor and sends it to the internet communication module, which shows the information to the user. The method used nowadays is done by manually populating tables which offer the risk of human error or data loss. The proposed system also consists of a web platform and an Android application that shows the real-time variables and generates reports of readings and alerts to unwanted variations. It could be able to modernize the process of monitoring the hospital’s departments using the Internet of Things (IoT).

This paper introduces the design of a warehouse temperature and humidity monitoring system based on a STC89C51 microcontroller. Compared with the traditional method, this system has the advantages of accuracy, sensitivity, short time and intuitiveness, and reduces the workload of the technicians and the cost of warehouse supervision. The greenhouse control system based on a microcontroller and digital temperature and humidity sensors can realize the automatic measurement and adjustment of temperature and humidity inside the greenhouse, which greatly reduces the labor intensity of operators, makes the greenhouse reach a more advanced management level, and is a low-cost, easy-to-use and accurate temperature and humidity measuring instrument, therefore it has a broad application prospect.

Humidity Monitoring

Aiming at the strict environment limit of existing technology and industrial production in the textile industry, a multi-point temperature and humidity monitoring system has been introduced based on the wireless sensor network. The data collected by the sensors was transmitted through wireless data transmitting module. And the base station will transmit the data received from this module to the computer after data processing. Thus the temperature and humidity data monitoring management has been realized in computer. This system is developed by using the Visual C++, and has realized the SQL Server database storage by using ADO technology. Finally, the environment monitoring in the textile factor has been received and the production requirements has been satisfied.
