Development of BLE Sensor Beacon Scanner

Abstract

Since the introduction of iBeacon by apple in 2013 there are many bluetooth low energy BLE beacons available from other manufacturers. The functionality of the beacon is extended to include sensors. The advantage of BLE sensor beacon is it has long battery life. The sensor need to upload its data to the Internet. This paper describes the development of BLE scanner using low cost processor module the ESP32, and using the Arduino IDE for software development. The uploaded data is displayed on a dashboard Grafana.
