The utilization of autonomous devices has disrupted conventional digital monitoring across diverse domains, particularly impacting environmental monitoring, agriculture, healthcare, as well as healthcare diagnostics. These contemporary autonomous deployables in the field enable dependable testing, gathering of data, and swift transmission of information. Among a variety of prevalent identifying techniques, the spectrophotometric approach stands out for its ability to precisely detect environmental samples at very low concentrations, offering cost-effectiveness and user-friendly operation. Consequently, this study focuses on designing a standalone, handy real-time nitrate concentration detection in water samples, employing readily available light-emitting diodes (LEDs) and photodi-odes with a peak response matching the absorption wavelength of the quartz cuvette in the spectrophotometric detection device. The end product is a portable, extremely sensitive, economical, and energy-efficient device. It integrates a display for offline transfer of information. In a proof-of-concept scenario, nitrate samples were spectrophotometrically tested, detecting nitrate in the linear range of 10–140 mg/L with a limit of detection (LOD) of 0.0072 mg/L. With suitable modifications to the optoelectronic components, the developed spectrophotometric detection platform could potentially be adapted to sense various analytes.

Objectives: To design a low-cost absorbance measurement device using a microcontroller that can be used for student's learning. Methods/Statistical analysis: The setup device is designed based upon Beer-Lambert Law with some LEDs through various sample solutions along with LDR at a different range of wavelength and the results are shown on a 16x2 LCD by use of a PIC16F877a microcontroller. The results are also compared with the standard colorimetric method. Findings: The setup device able to measure the absorbance of different colors of sample solutions at a wide range of wavelength (400-700nm) and measured by utilizing different LEDs to the transmitter end and an LDR at the receiver end. The proposed experimental device's performance was compared with the standard colorimeter for efficiency check. The efficiency of the setup device is near to the colorimeter of more than 95%. Novelty/Applications: For educational purpose, the proposed setup device is well affordable due to low cost (US$10.98) and easy to maintain because of compact size and data acquisition directly through microcontroller.

Recently, wireless body area networks (WBANs) and mobile Internet of Things (IoT) have been greatly increased and integrated into a different type of systems such as electronic/mobile-healthcare (e/m-healthcare) systems. In addition, analyzing the composition of drugs or performing the medical rapid tests in the conditions field are the main tasks of the m-healthcare system, in which the traditional laboratory methods of analysis are not suitable. Therefore, in this study, we proposed a novel structure with a distributed e-health system to perform such analysis, where portable infrared micro spectrometers are utilized and then boundary calculations are applied. More specifically, this system is proposed to use a portable infrared micro spectrometer with a specially designed application connected to a public communication network, which can process the results of analysis using boundary calculations. Moreover, it provides remote processing and long-term storage of analysis data using artificial neural networks and cloud technologies. Finally, simulation results show that preprocessing (error checking), data buffering and Edge Computing can significantly reduce the network latency and volume of transferred data.
