Methods Using USB host mode to develop Android app application, the function of spectrometer controlling, spectrum acquisition, sample measurement and SMS notification were achieved. Open source framework of SHH was used to build web services platform, realizing the service function of data monitoring, database storage and map labels of detection information. Android device could connect web cloud service to transfer and share data through the mobile network. Results Users only needed to download the corresponding model file on app program to detect sample target on the spot by near-infrared spectrometer, and smart cloud monitoring and management of critical data such as detection results, model information, detection time and terminal location were realized combined with network cloud services. Conclusion The system is stable and provides a direction for further development of micro near-infrared spectrometer.
