SenStick: Comprehensive Sensing Platform with an Ultra Tiny All-In-One Sensor Board for IoT Research

Abstract EN

We propose a comprehensive sensing platform called SenStick, which is composed of hardware (ultra tiny all-in-one sensor board), software (iOS, Android, and PC), and 3D case data.

The platform aims to allow all the researchers to start IoT research, such as activity recognition and context estimation, easily and efficiently.

The most important contribution is the hardware that we have designed.

Various sensors often used for research are embedded in an ultra tiny board with the size of 50 mm (W) × 10 mm (H) × 5 mm (D) and weight around 3 g including a battery.

Concretely, the following sensors are embedded on this board: acceleration, gyro, magnetic, light, UV, temperature, humidity, and pressure.

In addition, this board has BLE (Bluetooth low energy) connectivity and capability of a rechargeable battery.

By using 110 mAh battery, it can run more than 15 hours.

The most different point from other similar boards is that our board has a large flash memory for logging all the data without a smartphone.

By using SenStick, all the users can collect various data easily and focus on IoT data analytics.

In this paper, we introduce SenStick platform and some case studies.

Through the user study, we confirmed the usefulness of our proposed platform.
