Using the Internet of Things ( IoT ) in Smart Sensor Applications

(Smart ECG Sensor and Smart Breath Apnea Sensor):

Smart Sensor Software:

Modules developed does not contain analysis programs. Modules only acquire biological signals and send them to android tablets or mobile phones. Analyses are realized on the android tablets or mobile phones. Analysis programs and menus are developed on a desktop QT platform. In order to test the programs, a android kit is used in the QT platform for developed programs, it generates apk files.

Smart software of the IoT module runs on the android tablets or mobile phones. In smart ECG Sensor, software developed analyses ECG arrhymias, saves ECG signals to the memory card of a mobile phone and generate alarms for emergency, and sends all data to a server at the internet. In smart breath apnea sensor, software analyses both sounds of the breath and heart, and generate alarms for emergency.

IoT’s Hardware:

At each sampling time, scripts file are needed to acquire biological signals and to send the data to android equipments.

Script files are runned on the microprocessor of the ESP8266 or BlueGiGa modules (IoT). So, module does not contain extra microprocessor unit. Scripts use timers to generate the sampling frequency. The scripts read digital data from the ADC unit of the IoT modules at sampling time, save the data to its internal memory. And then, scripts send the data in a packet form to a android tablet or mobile phone by using wifi or bluetooth unit of IoT module. Script files for wifi-modules are downloaded to the module by using USB-UART converter. Script files for bluetooth-modules are downloaded to the module by using CC-Debugger.
