This project is solving the Sensor Yourself challenge. Description
The development of wireless sensor networks is an essential project for anyone interested in wireless communications for sensor networks, home networking, or device hacking. It is our first step in becoming proficient in making these space systems. No engineering or computer science background is expected or required. Those who have fooled around a bit with electronics or programming will certainly have a leg up, but in general, this project is aimed at hobbyists, students,makers, hardware hackers, designers, artists, and prototypers. We created little project using accessible environments, such as Arduino UNO R3, LM335 and XBee for hardware and Processing for displays. And I provided a full range of resources to outside our works for the electronics and networking novice. Whether you are our coleagues engineers, this project focuses on getting your work up and running as efficiently as possible. The projects we created here uses radio signals that pass invisibly through the air. This “wirelessness” is essential whenever you want to place sensors where no cables can be installed, or where such tethering is undesirable. With radio, you can employ sensing and actuation in pristine natural settings, minimalist building interiors, or complex planets environments. Mobile devices like children’s toys can benefit greatly by being communicative without being chained to the wall or to each other. The sensors can be attached to people or animals in a humane manner that doesn’t hinder their movement. In short, lots of data can move freely from where it is gathered to where it can do the most good. The ZigBee protocol is a very popular way of creating radio sensor networks for a number of reasons. Wireless networks and connected devices in general tend to be used in situations where power is hard to come by and must be conserved. Many times the communications these networks send are small in nature, compared to systems that transfer huge files such as videos.
Often, each device in the network transmits or receives unique information, so a robust system of individual addressing is extremely helpful. Security and design flexibility are frequently indispensable. That’s why our project focuses on ZigBee, the protocol defined by various space industry. In the past few years, ZigBee has found its way into commercial systems for home automation, smart energy systems, consumer electronics, industrial sensing, and health care. It features full addressing, many power-saving options, optimizations for efficiency in low-bandwidth applications, and a layered approach to communications design and security. Most importantly, ZigBee automatically forms entire networks that can heal themselves, routing around problem areas without manual intervention. Engineers are currently making use of this popular wireless protocol to create the systems that inform, enable, and delight their various users. We made this project to demonstrate how everyday people, not just electrical engineers and software developers, can develop these systems. A number of full sensor networks had been made by us.This project is about making networks using ZigBee radios. However, one reason we do this was our motivation for making space systems that are sensitive, active, reactive, and communicative—could just be some inherent desire to create the world we believe should exist: one where everything is imbued with a willful spirit and works together to help us live more richly. If so, this project is offered as a practical step in the right direction.
