Sensys Wireless Sensors Manage Traffic for 10+ Years

DALLAS, TX -- State and municipal agencies that face increasing traffic, pollution and fuel costs are turning to smart transportation technologies to solve their problems. Leveraging ultra-low power microcontroller (MCU) and RF technologies from Texas Instruments Inc. (TI) (NYSE: TXN), Sensys Networks' Wireless Vehicle Detection System has emerged as a leading traffic management solution because it operates accurately and reliably in harsh conditions for more than 10 years. The Sensys system combines state-of-the-art magnetic sensors with advanced packet radio technology, providing a cost-effective, dependable solution for a wide range of traffic management applications.

The Sensys wireless sensors are based on TI's MSP430F14x and MSP430F16x MCUs that run at ultra-low power levels to ensure maximum life of the system, drastically reducing maintenance effort and cost. The data from the sensors is transmitted real-time to a nearby location via TI's CC2430 RF transceiver, and is then transmitted to a local traffic controller or off-site traffic management system.

Key features and benefits of using TI's MSP430 MCUs and RF transceiver:

  • MSP430 MCUs ultra-low power consumption (<1 µs clock startup and <50 nA pin leakage) enables 10+ year battery life


  • Intelligent digital and analog peripherals integrated into MSP430 MCUs provide high performance, even during RF transmissions, and consume no power when not in operation


  • 16-bit RISC CPU architecture of the MSP430 MCU enables more effective processing, smaller size and high code density to maximize performance while minimizing memory and power requirement

CC2430 RF transceivers are the world's first IEEE 802.15.4 system-on-chip solution and operate in the 2.4 GHz range, making them ideally suited for reliable, low power digital wireless applications

TI's scalable MCU portfolio consists of hundreds of devices that meet varying price, performance and ultra-low power requirements

"Helping us to extend the life of our product well beyond that of our competitors, we chose TI's MSP430 MCU for its ultra low power capability," said Robert Kavaler, senior VP at Sensys Networks. "With TI's MCU and RF transceiver technology, we're able to offer the leading traffic management solution in the market."
