Design & Development of a Microcontroller Based on measuring Real Time Data and Interface with Mobile through Bluetooth

Abstract

We know smart phone is a big blessing in our daily life. Through the smart phone we can do several things. That simplifies our work. We can also use it as technology purposes. In this project, we have designed and developed an Arduino based measuring system. Here we use real time clock, Arduino uno, sensor, Bluetooth, signal conditioning circuit, and Android mobile. The system can measure radiation, time and temperature. Arduino read data from radiation sensor and save data in EEPROM. When we need those data then we paired our Android mobile with Bluetooth. Consequently we can read data in our mobile phone. Here, an Arduino board has been used as the main controlling unit, HC-05 module as the Bluetooth sensor. A program has been developed and burnt into the microcontroller of the Arduino module. The system is constructed and tested and found to work satisfactorily.
