TL;DR

This paper describes an educational project in which mechanical-electrical engineering students design and build an Arduino-controlled classroom fire-alarm prototype, integrating metrology, electronics, and programming. It reports that the prototype can monitor temperature and smoke and activate visual/audible alarms plus a simulated suppression system, and claims increased student knowledge, though without quantitative learning data.

Key findings

  • Students built a scale fire-alarm prototype using Arduino UNO, a DHT11 temperature sensor, an MQ-2 smoke sensor, a buzzer, an LED, relays, and a water pump; the Arduino code defines smoke sensitivity as 200 and activates alarm/suppression when thresholds are exceeded.
  • In practice #4, measured voltages across four resistors were V1 = 66.5 mV, V2 = 1.31 V, V3 = 51 mV, and V4 = 50.9 mV; the sum was 1.4784 V, approximating the 1.5 V battery and showing similarity between practical and theoretical results with measurement error.
  • The abstract and conclusions claim a significant increase in students’ knowledge of electronics, programming, and fire-safety parameters, and state that metrological calibration improves reliability and reduces false alarms; no numerical learning outcomes are reported.
  • The paper concludes that the Arduino-based system is viable for integrating accessible technologies to address safety in educational environments, with electrical diagrams and source code making the project replicable and improvable.

Methods

  • Design: practical implementation of theoretical principles by Ingeniería Mecánica Eléctrica students, combining direct application with descriptive analysis, experimental design, and systematic observation across four practices: a traffic light, a fire-alarm prototype, soldering cables, and multimeter measurements.
  • Data/sample: students at Universidad Veracruzana, Facultad de Ingeniería Mecánica Eléctrica; the number of students is not stated. The prototype uses Arduino UNO, protoboard, DHT11, MQ-2, buzzer, LED, relay, water pump, and related components.
  • Analysis: descriptive/observational evaluation of prototypes; multimeter measurements are compared with manual calculations, with no inferential statistics reported.

Limitations

  • The paper states that measurement error can arise from decimal places used in calculations, multimeter calibration, and pulse when measuring, so practical and theoretical values are similar but not identical.
  • The paper does not include a formal limitations section; evident from the text, there is no sample size, no quantitative pre/post assessment of learning, and no controlled fire test or false-alarm-rate data.
  • Evident from the text, the results and discussion are largely narrative and do not provide detailed outcome data for the alarm prototype or formal validation against NFPA/metrological standards beyond discussion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-13.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-13.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
