Our constructed projects
Fingerprint Attendance System
The fingerprint attendance system was developed using the R305 fingerprint sensor module, Arduino Uno R3 board, and the HC-05 Bluetooth module. An Android mobile application was installed on each tutor's mobile phone, which was used to record each student's attendance.
IoT-Based Weather and Air Quality Monitoring System
The Esp32 Wroom 32, DHT11 temperature and humidity sensor, and MQ-9 gas sensor module sent real-time temperature, humidity, and air quality data to an online web server. The data was stored in a CSV file and analysed using an HTTP web page and a separate PHP script. The Flask Python application trained Exponential smoothing, a time series forecasting model, to predict the next 5 hours' forecast.
Fire Rescue Robot
The fire rescue robot has the ESP32 WiFi camera, Lora, DHT11 temperature and humidity sensor, and MQ-9 gas sensor modules. The live feed video is sent to the PC Python application used by the fire rescue team to detect the presence of humans using the media pipe framework and to ascertain the burning building's temperature, humidity, and CO2 level.
