Android based Wireless Sensor Network (WSN) mobile application on humidity and temperature environmental monitor using CC2650 sensor tag

Abstract

This research proposed environmental sensing humidity and ambient temperature or object use CC2560 Texas instrument sensor tag device. This device will be implemented on a mobile app to detect surrounding humidity and temperature environment, hoping that it will be used to monitor the user’s daily activity. The sensor will transmit raw data to a central data collector mobile app using Bluetooth Low Energy (BLE) communication and configured with the other same device CC2650 sensor tag in a field with Wireless Sensor Network (WSN). Temperature and Humidity sensing was doing with distance to testing the accurate and sensitivity about the sensor device and the sensor is going work well when the time sampling in second time, the humidity and temperature can follow and change with real time sampling until 30s start from 30.12 and humidity start from 85.81 percent because of specification of the sensor device data transfer very fast wit Bluetooth Low Energy / multi-protocol 2.4 GHz and wireless MCUs with 352-kB flash and 80-kB SRAM, so the device get very little energy, low cost, and have good durability can access data and transmit for a long time.
