IoT-based Industrial automation for the Monitoring, Control and Data Processing of HVAC Systems
This blog was provided by Travancore
We've come so far with technology, and we've seen incredible advancements through the ages that once seemed impossible. From the connected home hubs, Bluetooth-enabled cars, smart thermostats, remote door locks, and every app-controlled device, the number of smart devices in our lives has gone through the roof. Thanks to Internet of things, also known as IoT, we have all these smart products in our daily lives making our lives better. Anyone with a smartphone or computer nowadays may obtain the data on the physical devices to which they are connected by simply connecting them to their computer or smartphone via the internet.
Let's take a deeper look at the case, solution, and impact of IoT-based industrial automation for HVAC systems.
Our client, a market leader in air conditioning, commercial facilities, and hydroponics, desired to streamline their Heating, Ventilation, and Air Conditioning (HVAC) industry through the use of IoT solutions that would enable a better understanding and diagnosis of HVAC system problems before they became a major inconvenience to the customer in the form of a health hazard or a significant financial expense to replace the equipment.
The client approached TA with patent-pending hardware and technology that monitors equipment and proactively warns and notifies contractors and homeowners so they may take action to diagnose the problem before it becomes a serious concern in terms of a health hazard or a significant repair expenditure. They wanted to build a platform that provides peace of mind to small business owners who are contractually bound to maintain the HVAC equipment in their rented space in order to prevent losing clients and revenue due to a lack of air conditioning.
Joining forces with the client's vision, our team developed a platform that examines the malfunctioning sensors, provides easy access to sensor details for customers and contractors, and warns consumers and contractors to abnormal sensor data. Both the hardware and the web interface were built by the team.
About the Hardware
We developed Sense1, an ESP32-based hardware platform with IEEE802.1 WiFi and sensor interfaces through BLE/I2C/SPI. Additionally, it supports a MQTT connectivity to a remote server. Sense1 works as a data acquisition node, acquiring data on a continuous basis and publishing it to a distant MQTT server.
Features and benefits
•USB power platform with built-in WiFi and Bluetooth
•MQTT supports TLS/SSL for encrypting connections between devices and the broker
•Easily scalable by adding more units
HVAC Monitoring System - Web Interface
The sensor nodes collect data and transfer it to web- or mobile-enabled devices, which subsequently notifies the users. It captures the sensor data in real-time and shows it on a web portal, on a mobile device, via color status notifications, as well as through email. Additionally, they provide mutual control between the fan and the air conditioner via the Internet of Things, based on a set temperature threshold.
Features and benefits
•User Management: Role-based users for each organization
°Add a sensor box and its details such as box name, box model, location, address, and mobile number)
°Grouping of sensory boxes into logical units to show the overall status of the group
°Highly scalable sensor pin configuration
°Sending sensor configuration to the device
•Dashboard: A map that illustrates the locations of sensors and shows the current status of the sensor
•Export Sensor Data: Download the sensor data as a report sheet based on a specified time period (both Individual and group)
•Graphs: View the sensor data as a graph based on a specified time period.
•Schedule the maintenance activities in each sensor boxes
As our lives grow increasingly complicated and fast-paced, the Internet of Things will undoubtedly become a vital component of them. Smart IoT-enabled HVAC systems can automate, keep critical control and maintain crucial data and provide a wealth of information relevant to customers, manufacturers, and maintainers. These forecasts and preferences will drive the flexibility and adaptability of smart systems around the world.
Implications of IoT-based automation
•More Control For Customers
•Early Alerts For Maintenance
Smart HVAC systems have already demonstrated their capacity to customize for users, produce maintenance warnings, increase comfort, and conserve energy, and they will continue to improve as IoT technology advances.
