Application of IoT to the Analysis of Food Constituents and Sensing Using a Sigle-Board Computer

Analog output from the HPLC detector was digitized using a single-board computer (SBC), and the processed data were distributed through a local area network by using the SBC as a web server. Results for the HPLC analysis of coconut oil was recorded on a client computer (PC). The output from two SBCs could be processed simultaneously in real time using a single PC. This system was also applied to the recording of temperature and relative humidity at a remote location. Data were acquired through the internet using a slower connection. Temperature and humidity could be recorded without their loss for three months by setting the acquisition interval longer.
