Accurate temperature sensing is a prerequisite for satisfying tenant/owner expectations for comfort control, and sensor location is critical to accurately measuring temperature. Installation difficulties can make sensor placement difficult, compromising project cost, timing, and quality.

Today, wireless technology is evolving rapidly. Past concerns regarding reliability, battery life, and cost have improved to the point where wireless is a practical alternative to traditional sensors in common applications. As a result, many new wireless zone sensors are now available. According to Frost & Sullivan market data, wireless sensor volume will approach that of wired by 2008.
