“…The relay module can accept current up to 10 A, can be used for both direct current and alternating current, receives a voltage of 5 V directly from the NodeMCU. It is designed to protect the control circuit from the power side, by using Opto couplers transmission, on all relays widely used to create smart home projects [24]- [26] in this research, it is used for turning on and off the water pump for watering plants, relay module as shown in Figure 5. A water pump is a small submersible water pump and operates on a voltage between 3 and 5 V, has a motor inside which pumps water in through the bottom holes and pumps out water from the side.…”

Cultivation of ornamental plants in the office is popular among office workers and the general public because it can create a good environment in the area, but the plant growers must pay attention to watering the plants, because it may cause the plant to die. With the advancement of internet of things (IoT) technology, used to control devices wirelessly, this research developed the smart flowerpot system that works through mobile and web applications, using a microcontroller to control the system and connect to users via mobile and web application that can monitor the system, and control the operation both directly and automatically. When soil moisture is reduced to a predetermined value, the system will order the plants to be watered automatically, and when the water level is almost completely reduced, the ultrasonic sensor will send a notification to the mobile application to let the user know, after testing the system, it was found that the smart plant pot can work efficiently and can automatically water the plants.

“…A relay is an electromagnetic switch that enables a low-voltage circuit to control the operation of a high-voltage circuit. It comprises a coil of wire that creates a magnetic field when an electrical current passes through it, an armature that is attracted to the magnetic field, and a set of contacts that can be opened or closed by the movement of the armature (Hameed et al, 2020). In this project, a relay was used to control the flow of electricity to the solenoid lock sensor, which is responsible for locking or unlocking the door automatically and protecting against overloads and short circuits.…”

In today’s digital age, computer laboratories’ adoption in academic institutions and the security of equipment are crucial to ensure their effective functioning and prevent equipment loss or damage. These laboratories have valuable equipment, such as laptops, switches, routers, projectors, printers, and scanners, that require proper security measures to prevent losses or damages. Manual methods such as pen and paper, spreadsheets and tracking software have been commonly used in the past for equipment tracking. However, these approaches have certain limitations, such as being time-consuming, having limited storage and retrieval abilities, and not providing real-time updates. To overcome these challenges and enhance the lab equipment tracking system, the objective of the developed system is to identify the necessary requirements for designing, developing and validating an IoT-based computer lab equipment tracking system to manage high-value lab equipment at Université du Lac Tanganyika (ULT) university and prevent the unauthorised removal of equipment from the laboratory. The study employs Radio Frequency Identification (RFID) technology to track and identify automatically tags attached to the equipment. This study used Agile’s Scrum framework as a system development approach, and a qualitative research approach, including interviews, observations, and focus group discussions, was used to collect data for the functional and non functional requirements. An ESP32 microcontroller was used to collect and process data from sensors and send the data to the IoT cloud. An Advanced Encryption Standard (AES) encryption and decryption algorithm using a 128-bit key was implemented to ensure the secure transmission of RFID data. The system also features an automatic lock-unlock mechanism to prevent equipment from moving out of the lab without authorisation. A web application with a simple interface was developed for the equipment management system. Ultimately, the system validation process engaged 51 participants comprising IT managers, lab assistants, lab technicians, and lab users. All participants filled out a system evaluation form which resulted in positive responses. The results of the system validation analysis indicate an average of 87% of performance, availability, accuracy, efficiency, and effectiveness. Therefore, ULT University accepted the system due to its effectiveness, security features, and user-friendly interface.
