Bluetooth Low Energy is an interesting short-range radio technology that could be used for connecting
tiny devices into the Internet of Things (IoT) through gateways or cellular networks. For example, they are widely
used in various contexts, from building and home automation to wearables. This paper proposes a method to
improve the use of smartphones with a smart wireless sensor network acquisition system through Bluetooth Low
Energy (BLE). A new BLE Smart Sensor, which acquires environmental data, was designed and calibration
methods were performed.
A detailed deviation is calculated between reference sensor and sensor node. The data obtained from laboratory
experiments were used to evaluate battery life of the node. An Android application for devices such as
Smartphones and Tablets can be used to collect data from a smart sensor, which becomes more accurate
