Chips, sensors and apps
Dialog Semiconductor is a world-leading creator of mixed signal circuits, targeting low-energy, mobile appliances, such as smartphones, tablets and wearables.
Internet of Things sensor app
We have created an app that reads out six different sensors and displays these real-time in different graphs. The data can be interpreted and displayed in different ways. For instance, we use the data of a 3D accelerometer to display the movement of the device by moving around a 3D cube in the app. Gyroscopic data is used to display the rotation around 3 axis, visualized by a 3D sphere.
The device also offers fusion data, combining data from multiple sensors into quaternion data, enabling us to determine the actual orientation of the device with much greater precision. We use the famous Utah teapot to represent the orientation of device in the app.
SmartTags are small, keyfob-sized devices with a proximity device inside. An app can connect to the device and determine the distance from the device, by using the strength of the radio waves (RSSI values) and converting it to physical distance.
