Design and Implementation of a Car’s Black Box System Using a Raspberry Pi and a 4G Module

Round 1

Reviewer 1 Report

Overall the article is good and suggest to be accepted for this journal. Authors capable to explain the works the they conducted and explain results obtain from the research. Follow the existing format and easy for other researchers to understand the work done.

But is better if author can add certain item as:

1. Is good to have subtopic of Previous Work, where authors can explain the previous research or work that has been conducted by other researchers.  

2. References - Is good if authors can further refers to latest journal article from 2017 to 2022.

Reviewer 2 Report

In the manuscript of applsci-1738947, the design and implementation of a car´s black box system using a raspberry pi mi-crocomputer and an Internet of things (IoT) module was presented in this research work. This system was built using a microcomputer raspberry pi and different sensors, such as: GPS, camera module, audio module, alcohol sensor module, and signals from Electronic Control Unit (ECU). The data were stored in a SD card, and they were stored in the cloud too using Waveshare SIM7600G-H 4G module and using the ThingSpeak platform.  Overall, the topic is very interesting and the article seems full of content. Moreover, it will be appropriate to consider the following corrections and comments.

1. Please also avoid "lump sum references", such as XXXXX [1-5]; all references should be cited with a detailed and specific description. In the references, all authors should be included, avoiding using "et. al.";

2. The car's engine promise many advantages to improve car's performance and parameter characteristics. For clarification, the authors should refer to Potential improvement in combustion and pollutant emissions of a hydrogen-enriched rotary engine by using novel recess configuration; Parametric analysis of hydrogen two-stage direct-injection on combustion characteristics, knock propensity, and emissions formation in a rotary engine.

3. Line 76-79, these sentences look like the conclusions of the present study, they are not fit to be in this place.

4. Please avoid using abbreviations in the TITLE, HIGHLIGHTS, ABSTRACT and CONCLUSION if possible. 

5. CAPTIONS: Captions for figures and tables should be presented with more specific description rather than a general sentence like "Results of the experiments ...", "A studied system ...."

6. An updated and complete literature review should be conducted to present the state-of-the-art and knowledge gaps of the research with strong relevance to the topic of the paper.

Reviewer 3 Report

The article presents the design and implementation of a car black box system using a Raspberry Pi and an IoT module. Many sensors are used and their data can be recorded in a SD card or in Cloud. The article describes the blocks/modules that composes the system without the necessary details. In this way, it is a straightforward work but scientifically minor. Please provide more technical details about the proposed work.

The novel features implemented by the system, in face to other similar systems, must be clearly stated in the Introduction.

Use in all the figures the English language, e.g. Figures 6, 9, 10, and 11.

The list of references must be augmented and updated.

Reviewer 4 Report

The following comments may help the authors to improve the manuscript before acceptance:

1. The authors should upload the python code so that the reader can follow it.

2. The GUI of the software is not in an English language. 

3. A list of materials used in the set-up and where to purchase them should be include in the supporting material.

Round 2

Reviewer 2 Report

The current form can be accepted.

Reviewer 3 Report

Essentially the same paper as previous version. Almost only a functional description of modules is given. Not technically sound.

Reviewer 4 Report

I do not have further comments
