Air pollution is one of the environmental problems that must be solved. Heavy transportation and industrial activities may cause poor air quality and inhaling pollutants, such as CO and CO2, for a long time may damage human health. Therefore, it is necessary to have an air quality monitoring system which gives information of hazardous gases concentration from time to time in certain area. This study aims to design and build a monitoring and measurement system for CO and CO2 in the environment using wireless sensor network (WSN) with ZigBee based wireless network technology. The experimental results show the proposed system is able to provide the air quality monitoring in real time through WSN technology. In order to have accuracy measurement results, those sensors used in the developed system are compared and calibrated to reliable standard instruments. DHT 22 sensor works well as a sensor to read the temperature and humidity with an average error value of 0.14 °C and 0.1% RH, respe...
Implementation of embedded real-time monitoring temperature and humidity system
Indonesian Journal of Electrical Engineering and Computer Science, 2019
Temperature and humidity are among the parameters that significant to the industrial and agricultural. Traditionally, these elements are monitored inefficiently through wired monitoring system that caused higher implementation and maintenance cost. In addition, the device to detect the temperature such thermometer is not suitable for real-time monitoring since it need a longer response time to measure. With the advent of wireless technology, the temperature and humidity are monitored remotely and effectively. This paper aims to describe the implementation of an embedded real-time temperature and humidity monitoring system, using Arduino for Internet of Things (IoT) application. The system integrates the Arduino node with a dashboard system call Node-FRED, which interfaced to the LoRa radio through the Things Network gateway. This IoT application is deployed on both indoor and outdoor environment, to investigate the relation between the temperature and humidity level in order to man...

Air quality of any indoor area has been a major issue to be maintained since nowadays a lot of indoor activity occurs more often. The existence of a system to measure, analyze, and present the data of Indoor Air Quality (IAQ) is needed on most modern buildings. This paper presents a preliminary sensor node design to measure temperature and relative humidity for indoor IAQ monitoring applications. Compact and low-power features were considered in the design. The sensor node was designed to serve as a base operating device that has built-in wireless transfer data to be monitored using the Internet of Things (IoT). A temperature and relative humidity sensor from MikroElektronika (SHT click) is used as a primary sensor that detects both the temperature and humidity simultaneously. The AVR board has been chosen because of its compatibility with an ATMega4808 and WINC1510 are the main components for an IoT board. For standalone operation, a rechargeable battery was applied to be the main energy source for the sensor node placed in any location within a room. The designed sensor node was verified with an actual parameter for measurements under a real-life situation. The experiment results reveal that the designed wireless sensor node can run autonomously and monitor the indoor room temperature at an average 25°C and relative humidity at 52–54 % in real-time sampling that can be shown from the IoT Cloud Interface.

Atmosphere surrounds the earth. All the living beings are surrounded by the atmosphere .So we need to measure different parameters of atmosphere which have the impact on human health. The various parameters include the atmospheric pressure, humidity and various gases. This project is a simple wireless sensor based air quality monitoring and data acquisition system for industrial and urban areas. The framework comprises of temperature sensor, humidity sensor, pressure sensor and a set of gas sensors (like carbon monoxide, smoke). In case of unexpected values the system sets the buzzer on. Wireless transmission is efficient technology which can accumulate and measure parameters from real world. KEYWORDS: Wireless sensor; air quality monitoring
Objectives: Home automation is achievable with an integrated approach using Wireless Sensor Networks (WSNs). This paper presents the implementation of such integrated approach to automating the air-conditioning of various apartments. Methods/Statistical Analysis: The developing of an integrated system consisting of network of wireless sensor nodes with well selected components and resourceful capabilities is explained. This network is incorporated to a control unit connected to air-conditioning systems in various home apartments for automation and central remote control through short service message (sms). Findings: An integrated system comprising three resulting characterized sensor nodes and one sink node being integrated with the automated control unit for the air-conditioning systems were implemented and tested. The system was designed with well selected intelligent temperature/humidity DHT22 sensors, homogenous XBee radios, arduino boards and wireless network protocol to deliver remotely monitored parameters from the sensor nodes to a base station. The resulting composite units of the implemented system were products of the best parameters trade-off in the selection of components and protocols. The same sensor nodes can be increased to the number of target apartments and integrated to the network system. The transfer of monitored data to the central hub was wireless and the mode of sending commands to the control unit was through short message service. The approach conserves energy consumption as it saves the loss time involved in continuous operation of air-conditioning systems. The system also reduces the health risk in poorly air-conditioned environment for elderly and infants. Applications/ Improvements: The approach can be extended to controlling other appliances in full home automation set-up.
