We offer a range of sensor beacons but what each beacon actually senses or detects is buried deep in the respective beacon descriptions.
As we have recently added new sensor beacons, we have updated our downloadable pdf showing what each beacon can detect.
If you want to know how you might use these beacons, take a look at our articles on Beacon Proximity and Sensing for the Internet of Things (IoT), Using Bluetooth LE and Using Bluetooth LE Sensors.
