Air Quality Monitoring: A Vital Project for Cleaner Air
The purpose of air quality monitoring is to ensure that the air we breathe is safe and healthy for both humans and the environment. By collecting and analyzing data on air quality, we can identify areas where pollution levels are high and take steps to reduce emissions from various sources, including transportation, industry, and agriculture. Air quality monitoring is an essential tool in protecting public health and the environment, and it plays a vital role in promoting sustainable development and creating healthy, livable communities. One of the significant efforts towards this goal is the Air Quality Monitoring system developed by our team for the city of Čačak. The system utilizes sensor nodes that acquire real-time data on particle matter concentration. This data is then presented on a custom web platform, which provides graphical and map representation of the current and historical air quality data. The platform also offers recommendations to the population, depending on air pollution levels. Electronics were developed using ESP32 microcontroller along with PMS7003 and BME280 sensors and were designed to comply with the IP65 standard for outdoor use. Additionally, a web platform was developed using the Yii2 framework. It can be easily configured to work with any geographical area, making it a versatile solution for air quality monitoring.
Smart Electronics for Controlling Electric Heaters
Smart electronics for controlling electric heaters is a technology that allows users to control their electric heaters remotely. It is a system that includes a microcontroller, sensors, and communication modules that work together to provide users with the ability to monitor and adjust the temperature of their heaters from anywhere in the world using a smartphone app or other devices. The real-life application of this technology is vast. It can be used in homes, offices, hotels, and other facilities to control the temperature of individual rooms or zones, providing personalized comfort to occupants.
One of the significant benefits of using smart electronics for controlling electric heaters is that it provides more precise temperature control than traditional thermostats. With sensors that can detect the temperature and occupancy of a room, the system can adjust the temperature to a more accurate degree, ensuring optimal comfort while reducing energy waste. Another benefit is the ability to remotely monitor and adjust the temperature of the heater. Users can use their smartphone app or other devices to turn on or off the heater, adjust the temperature, and even set schedules for when the heater should turn on or off. This feature provides convenience and flexibility, allowing users to control their heaters from anywhere, at any time.
Our team has developed smart electronics for controlling electric heaters, which includes features like overheat detection, window open detection, and phase controlling. A mobile application was also developed to control the heaters remotely, providing easy access to temperature control, planning, and adaptation. We utilized the ESP32 microcontroller in the electronics and incorporated a triac with zero-crossing detection to regulate the heaters and minimize electrical noise during the switching process. The power level supplied to the load can also be adjusted by altering the delay time between the zero-crossing and trigger points of the triac. Furthermore, two native mobile applications were developed for iOS and Android platforms. The smart electronic solution was delivered to a large German company with a global presence as a final product, making it a highly successful project.
Pellet Heating System Regulation: A Greener Solution
Pellet boilers have become a popular and eco-friendly heating solution for homes and offices. They are efficient, reliable, and can help reduce energy costs. However, managing the operations of a pellet boiler can be a daunting task, especially for those who are not familiar with the technology. To address this issue, our team has developed pellet electronics that can manage the operations of pellet boilers according to the client’s specifications. We have also created a web platform that allows maintenance workers to easily adjust pellet boiler settings, ensuring optimal performance and efficiency. In addition, we have developed a mobile app for customers to control their pellet heating systems, making the entire process more accessible and user-friendly. The PCB we designed consists of two microcontrollers, namely ESP32 and Atmega328P. We have also created various modules for controlling fans, pellet dispensers, and measuring smoke temperature. In addition, two native mobile applications were developed for both iOS and Android platforms, and a web platform for repairers was created using the Yii2 framework. With the help of pellet electronics and our web platform and mobile app, the management of pellet heating systems has become much easier and more efficient, allowing homeowners and businesses to enjoy the benefits of this eco-friendly heating solution without any hassle.
Smart Thermostat: A Smarter Way to Control Home Heating Systems
Smart thermostats are becoming an increasingly popular choice for homeowners who want to optimize their energy consumption and maintain a comfortable temperature in their homes. They are designed to learn your heating and cooling preferences and adjust the temperature accordingly. One of the advantages of smart thermostats is that they can connect to the internet, allowing users to control the temperature remotely through their smartphones or other devices. Additionally, smart thermostats are equipped with sensors that can detect movement and adjust the temperature based on the occupancy of the room, making them even more energy-efficient. The electronics were developed using various microcontrollers such as PIC16F families, ESP8266, ESP32, among others. Two native mobile applications were created for both iOS and Android platforms. Our team has been engaged in R&D of large numbers and types of wired, RF, and WiFi smart thermostats that maintain stable temperatures, prevent large swings and temperature changes, and have been successfully implemented by several companies to control home heating systems, making them a valuable addition to any home.
We can say that the world has been transformed by embedded systems and the Internet of Things (IoT), opening up a multitude of opportunities for ground-breaking projects. The advantages of these technologies are widespread, ranging from boosting efficiency and cutting costs to supporting sustainability and safeguarding public health. Our embedded journey presented in this article displays the potential and influence of embedded systems and IoT across diverse fields. As technology continues to progress, we can anticipate even more advanced and sophisticated solutions that enable us to work and live smarter in an interconnected world.
