This research is conducted to build portable spectroscopy optic with Android and desktop applications. Portable spectroscopy optic consists of Arduino Micro, Nextion Liquid Crystal Display (LCD), 2 pieces Light Emitting Diodes (LED), servo motor, diffraction grating (600 lines/mm), 2 pieces photodiodes, Bluetooth HC-05, and SD Card Reader Writer. Android and desktop applications realized by using Qt IDE. Spectroscopy testing is done using polymers with color red, green, and blue. The result of polymers sample testing shows that the spectrum with same wavelength range as the sample color will be passed, while other wavelengths will be absorbed. The device has been able to measure absorption of sample. On testing restore the test results to the SD card produces file with size about 2 kB. Device uses battery with capacity 3000 mAh and can be actively sustainable during 3 hours 31 minutes. Testing of communication Android and desktop applications with spectroscopy is done using bluetooth and Universal Serial Bus (USB) cable. The result of application testing are already able to send and receive data from spectroscopy.

Humidity Monitoring

The temperature and humidity monitoring system was developed using various components viz., Arduino Uno, DHT11 sensor, universal serial bus (USB) type B cable, adaptor, DC power jack, 9-V battery connector, 9-V DC battery, resistor, liquid-crystal display (LCD) screen, trimmer potentiometer, light-emitting diode (LED) bulbs, jumper wires, micro secure digital (SD) card module, printed circuit board (PCB), etc. The field testing of the developed temperature and humidity monitoring system was carried out at various locations of the college campus. It was observed that the system worked between the percent variation of 0–8.00% for temperature and 0–5.97% for humidity. The developed system showed the accuracy of ±2°C for temperature and ±4% for humidity. The total cost incurred for the development of temperature and humidity monitoring system along with all accessories was ₹1625.
