WIRELESS TECHNOLOGY |
||||||||
| Remote Monitoring using Wireless Sensor Networks (WSN), Bluetooth, Wife, Zigbee technologies Many Wireless Technologies are RF, Bluetooth, Wi-Fi and Zigbee have been developed and remote monitoring systems using these technologies are popular due to flexibility, low operating charges and etc. so in our project using Bluetooth technology. Today Wireless Sensor type of Network are used an increasing number of solutions, aimed at implementing control system and distributed monitoring in a great number of different application areas. It is designed a general purpose controlling module designed with the capability of controlling and sensing up to five devices simultaneously. The communication between the remote server and controlling module is done by using Bluetooth. The Bluetooth server can communicate with much such type of modules simultaneously. The controller was based on microcontroller and Bluetooth communication TDK Blu2i (Class 1) module which provides a serial interface for data communication. The controller was deployed in a cybernation of home application for a selected set of electrical devices. Home appliances control system operated over a Bluetooth with a smart phone, which enables remote-control, fault-diagnosis and software-update for home appliances through Java applications on a mobile phone. The system consists of home automation is smart phone and Bluetooth adapter, used for communicate with appliances. Bluetooth consists of a 20MHz, SRAM and 16bit CPU. The adapter of communication board is connected to the home appliance and to the cellular phone through serial ports. The home appliances can communicate with the cellular phone control terminal via Bluetooth SPP. On the contrary, the communications between TM and CC occurs in once a day for data-logging purposes, while alarms are communicated asynchronously, by means of Short Message Service (SMS). Prototypes have been realized to interface with temperature (T, AD590), humidity (RH, HumirelHM1500), and carbon monoxide (CO, Figaro TGS2442) sensors. DECT Siemens GSM module MC35 and module MD32 were used. It was based on Microchip's PIC18F452 microcontroller and TM was designed using 32-bit ARM based microcontroller from Samsung (S3F441FX). It described details of the design and instrumentation of variable rate irrigation sensor network and software for real-time infield sensing and control of a site-specific precision linear-move irrigation system. Field conditions were site-specifically monitored by six in-field sensor stations distributed across the field based on a soil property map and periodically sampled wirelessly transmitted to a base station. An irrigation system machine was converted to be electronically controlled by a programming logic controller(PLC) (Siemens S7-226 with three relay expansion modules activated electric over air solenoids to control 30 banks of sprinklers) that updates geo-referenced location of sprinklers from differential Global Positioning System (GPS) and wirelessly communicates with a computer at the base station. The communication signals of sensor network and irrigation controller to the base station were successfully interfaced using low-cost Bluetooth wireless radio communication through Bluetooth RS-232 serial adaptor (SD202, Initium Company). The major strengths and weaknesses drawn from the conclusions laid by various researchers are as under Major strengths. | ||||||||

Each sub activity has different colours and also has different room OK icons and at centre we have voice icon which shown as microphone symbol. HC serial Bluetooth products consist of Bluetooth serial interface module and Bluetooth adapter, Bluetooth serial module is used for converting serial port to Bluetooth. There are two MCUs want to communicate with each other, while Bluetooth master device connects and then other one connects to slave device. Their connection can be built once the pair is made. This connection is equivalently by Bluetooth, liked to a serial port line connection including RXD, TXD signals. The Bluetooth serial module used to communicate with each other. When MCU has Bluetooth salve module, it can communicate with computers Bluetooth adapter and smart phone. There is a virtual communicable serial port line between MCU and computer or smart phone. The Bluetooth devices in the market mostly are salve devices, such as Bluetooth GPS, Bluetooth printer. So, master module we need to make communicate. Bluetooth Serial module’s operation doesn’t need drive and it can communicate with other Bluetooth device has the serial, but the communication between two Bluetooth modules required at least two conditions, the communication must be between slave and master, The password must be correct. However, the two conditions are not sufficient. There are some other conditions based on different device model. In the following chapters, we will repeatedly refer to Liver’s (Formerly known as Guangzhou HC Information Technology Co., Ltd.) material and photos.
