Monitoring of the health of bee colonies, their efficiency and activity and nectar flow are essential for beekeepers. Such information could be obtained by using innovative technologies and systems. Such technologies are increasingly used in different types of agriculture, including beekeeping. To monitor the aforementioned parameters, smart electronic scales measuring the weight of the hive and sending the data to a server platform are most often used. The aim of this paper is to present a configurable system enabling long-term autonomous operation, monitoring the status of bee colonies and environmental conditions. The system consists of electronic scales and additional modules.

Water scarcity is a growing problem in many regions. Therefore, intelligent management of the available water is needed. Aside from using water mains directly in households and farms, hydrophores are often used for local water system creation. Water tanks are filled with water when available in the water mains, and then the water is extracted with a hydrophore. Wells are also used as alternative water sources. Filling the tank manually requires human presence and can lead to water overflow. It is also better if the hydrophore is protected by switching it on or off depending on the water level measured, current, and pressure in its balloon. This paper presents a water management system designed to address these issues. The system utilizes various sensors to monitor water levels, pressure, and current. Microcontrollers analyze sensor data and control hydrophores and valves based on user-defined parameters. The system offers remote monitoring capabilities and can be configured for different water source scenarios (tanks vs. wells). The system was successfully implemented in real-world settings, including a factory. The benefits of the water management system include hydrophore protection, autonomous water management, and valuable data on well recovery rates and hydrophore operation cycles.

This paper presents a case study on the integration of embedded IoT hardware with a modern Android application, demonstrated through the development of a compact autoclave system for small-scale food sterilization. The device is controlled by an ESP8266-based module and communicates securely with a Kotlin-based Android app via MQTT using HiveMQ. The app incorporates advanced Android design patterns such as coroutines, LiveData, Navigation UI, and DataStore. Each device is uniquely addressable and fully configurable from the mobile interface. The work highlights Android’s role as a powerful interface for managing embedded IoT systems.
