ParQSense Smart Sensor Powered by Silicon Labs' Wireless Technology Helps Car Drivers Quickly Find Open Parking Spots

Q-Free  and Silicon Labs announce a collaboration on a new outdoor parking IoT sensor solution that makes it faster and easier for automotive drivers in urban areas to locate open parking spots. The companies have worked together to create Q-Free’s ParQSense Smart Parking Sensor, which uses the Silicon Labs’ Wonder Gecko wireless microcontroller (MCU) for control and Sub-GHz connectivity. The Q-Free solution was deployed as a pilot this year in the EU (UK, Netherlands, Sweden and Norway) and North America, and will be released for commercial use on Sept. 17.

With more than 30 years in the intelligent transportation market, Q-Free has focused its resources on developing ways to reduce traffic flows. Q-Free provides a wide range of transportation technologies including electronic tolling, vehicle counters, surveillance technologies and parking management solutions. The ParQSense Smart Parking Sensor is one of the company’s first sensor products to support outdoor parking needs. According to an INRIX study, 20 percent of traffic in urban areas can be attributed to drivers searching for parking spots.

Many existing outdoor parking sensors on the market prior to the Q-Free solution had accuracy limitations, and struggled with wireless capabilities and interference from cellular networks commonly associated with urban environments.

The Q-Free ParQSense solution uses dual radar and magnetic field technology to sense with 99+ percent accuracy whether a vehicle is present in a parking space. The application transmits data to centralized base stations over ultra-long distances using narrowband sub-GHz wireless connectivity.

During the product development phase, Q-Free recognized low-power wireless connectivity would be crucial in ensuring the viability of the solution. The primary product design obstacle was offering a combination of high accuracy components with extreme low power consumption, a challenge Silicon Labs routinely solves for customers.

The Q-Free ParQSense Smart Parking Sensor product line will be available for commercial release Sept. 17, 2018. Please contact Q-Free for information on pricing.
