A new sensor has been created called Density, that has been designed to be positioned in the doorway of a location such as a coffee shop or restaurant. To enable users to them check using the companion application or website just how busy the location is.
The Density sensors can be installed into a premises for free and require a monthly fee of juts $25 per month to run the system.
The creators of the Density Sensor system explain a little more :
Our sensor gets attached to a place’s entrance, measures anonymous movement as people come and go, and generates real-time and historical data that can be integrated anywhere.
We install sensors across your network of locations (ex. a set of small businesses, a college campus, or museum). Real-time movement data is collected, organized, and made available to your developers through the Density API.
Density uses infrared light to measure movement. By design, Density cannot capture any personally identifiable information about consumers.
For more information on the new Density jump over to the official website for details as well as APIs that are available for developers to utilise.
