This paper presents the development of an energy efficient environmental sensor that sends measurement data to a cloud platform using HTTP (Hypertext Transfer Protocol) requests. The device is based on a programmable system-on-chip (PSoC), and is equipped with a temperature and relative humidity sensor for taking measurements and with a WLAN (wireless local area network) module for sending data to...
Living conditions in any country are important, especially a local environment is more important to many people. The parameters like a noise level, light intensity, barometric pressure, carbon monoxide (CO) and carbon dioxide (CO2) concentration levels are monitored to evaluate living conditions. The mentioned reasons led to the practical realization of Wireless Unit for Environmental Monitoring (WUEM)...
Current study shows that the advances in wireless sensor technology create a chance to promptly and effortlessly deploy low-cost, wide-scale and a network of low-power sensors across moderately considerable environmental areas. Additionally, the advancement and increase of small but affordable wireless hardware is further completed by the open source software components that rapidly developed. A variety...
The paper presents a wireless sensor network system, including 433 MHz, ZigBee wireless network, data collection node and data concentrator node. This system is mainly to apply to monitoring winery's environment, the principle of which is that data collection node uses 433 MHz wireless network to send data, data concentrator node uses 433 MHz wireless network to receive the data from data collection...
Integration of sensors, embedded operating systems, wireless networking technology, wireless sensor networks, is a new information gathering and processing technologies, in environmental monitoring has a very good application and advantages. This paper introduced a method model based on ZigBee-technology. Depending on specific situation in environment, LEACH communication protocol was chosen. The...
Wireless system is one of the technologies currently applied in agriculture to improve quality, save labour costs, increase yields, and conserve water. A real-time wireless monitoring system for measuring climatic environment parameters of rain shelter house (RSH) for chili plantation was developed. The wireless monitoring system integrates the hardware and software components for the measurement...
A kind of environmental monitoring system based on wireless mesh network with the core of embedded system ARM9 S3C2410 microprocessor is presented in the paper. The flexible and self-organizing wireless mesh network is used to achieve the real time acquisition and multi-hop wireless communication of parameters of the monitoring atmospheric environment such as SO2, NO2, NO, temperature, humidity and...
Wireless sensor networks (WSN) are a nascent technology that builds upon the recent decadepsilas advances in electrical and mechanical engineering including wireless communications, low-power embedded systems, MEMS-sensor design, network architectures and instrumentation applications. These networks promise a means by which to better monitor and understand environmental monitoring, precision agriculture...
