Implementation of vehicle ventilation system using NodeMCU ESP8266 for remote monitoring

by beei iaes

2021, Bulletin of Electrical Engineering and Informatics

In this paper, an implementation of vehicle ventilation system using microcontroller NodeMCU is described, as an internet of things (IoT) platform. A low-cost wireless fidelity (Wi-Fi) microchip ESP8266 integrated with NodeMCU provides... more

Figure 1. Security issues in loT system [19] The entire IoT system must have properties such as confidentiality, integrity, authentication, authorization, availability and privacy to guarantee security in IoT [19, 20]. Figure 1 depicts the major challenges in enhancing security in IoT environment. This section provides review on the security aspects implemented in two IoT applications, specifically vehicle and home security system.

Figure 6. The vehicle ventilation system connection and timer are among of the widgets available in the application. Figure 8 (b) gives an example to configure the setting of Button Widget. The output pin was configured to link up using Android development software installed in the NodeMCU ESP8266. A Firebase Library installed in the Android to provid cloud services to the mobile application. As shown in Figure 9, Firebase provides functionality like analytics, databases, messaging and crash reporting which are recommended for future work.

Figure 10. The blynk platform, (a) Reading temperature page, (b) Control accesorries page Figure 10 (b) shows the Control Accessories page, as defined, to control the vehicle accessories connected to the NodeMCU controller. Notifications were sent to the mobile plaltform whenever the temperature exceeds a pre-defined threshold and/or rain starts to fall. These would allow the users to control the vehicle accessories according to the received notifications. Figures 11 (a) and (b) depict the notification when the temperature exceeds 35 °C and when rain starts to fall.

Graph in Figure 12 presents the results obtained by collecting the temperature reading in a vehicle. The average temperature before the ventilation system in the morning is 28.5°C while after the ventilation, its average is 24.2°C which about 4.3°C difference. In the noon, the average temperature is 51.2°C before the ventilation system and 38.8°C after the ventilation which about 12.4°C difference. The average temperature stated that in evening is 40.4°C while is 33.3°C after turning on the ventilation system with 7.1°C difference. The temperature is reduced about 19.8%.
