Abstract The growing ability of high‐performance consumer electronics is fostering innovation in prototyping and research. Although the Raspberry Pi single‐board computer (SBC) widely used across various fields, including diagnostics, applications involving UV‐based reading remain underexplored. In this study, a simple, low‐cost (less than 100 euros), portable device for UV–vis measurements based on presented. system integrates AS7341 multi‐channel multispectral digital sensor, offering analytical performance comparable to two commercial spectrophotometers – one benchtop terms linearity, limit detection, quantitation, repeatability. Furthermore, demonstrates reliable both analyzing real wine samples using different enzymatic kits quantifying concentrations synthetic DNA oligonucleotides. By providing ready‐to‐use, portable, affordable platform prototype well‐suited resource‐limited settings, educational environments, IoT where numerous distributed sensors are required specific diagnostic tasks.

Este estudio se centra en el diseño e implementación de un sistema basado Internet las Cosas (IoT) para monitorear la calidad del aire centro Quevedo (Ecuador), que utilizando sistemas embebidos como Arduino Mega y Raspberry Pi, integraron sensores específicos, PMS3003 material particulado (PM2.5) MQ-7 monóxido carbono (CO). Estos dispositivos permitieron recopilar datos tiempo real sobre los contaminantes, cuales fueron procesados almacenados base InfluxDB, con visualización a través plataforma Grafana. El análisis realizó durante ocho meses, cuyos niveles máximos CO alcanzaron 49.28 ppm, mientras concentraciones PM2.5 registraron máximo 5.35 ppm. Estas cifras, aunque significativas, encontraron por debajo alerta establecidos normativa nacional Organización Mundial Salud (OMS), indicando no representan riesgo crítico salud humana. Sin embargo, identificaron patrones relacionados factores climáticos actividad vehicular. Los contaminantes aumentaron períodos mayor radiación solar baja ventilación, disminuyeron condiciones viento menor tráfico mostró ser una herramienta eficiente monitoreo ambiental, destacándose su bajo costo capacidad adaptación. Se recomienda ampliar cobertura otras áreas urbanas promover educación ciudadana impacto emisiones vehiculares aire. Este proyecto demuestra potencial tecnologías IoT enfrentar desafíos ambientales contextos urbanos.

Lithium‐ion batteries (LIBs) are widely used for energy storage in various industries due to their high density and long lifespan. However, degradation mechanisms may lead hazardous conditions, such as thermal runaway. Solely relying on capacity changes state of health (SOH) assessment is insufficient, given the complexity LIBs. This work introduces comprehensive real‐time insights prediction (CRISP), a novel framework SOH identification. Using data from commercial LIBs, CRISP runs low‐cost Raspberry Pi with remote monitoring capabilities, generating aged anode half‐cell voltages each reference performance test (RPT) references lithium plating assessment. processed RPT ≈2.9 s outputs multiple physical quantities evaluation. Results show that LIBs cycled at 100% depth discharge (DOD) exhibited greater cathode material loss compared those narrower DODs. no dendritic deposition detected by evaluating correlating parameters provided CRISP. In summary, this study highlights importance multi‐parameter assessment, demonstrating single‐parameter methods (e.g., capacity‐based) fail capture full scope health.
