Case study Enhancing Classroom Safety: CO2 Monitoring in North West England Schools 20 October 2023 The presence of high levels of carbon dioxide (CO2) in school classrooms has been linked to various adverse effects on students, such as headaches, fatigue, and difficulties concentrating, ultimately impacting their academic performance A group of 12 schools in North West England implemented Halo Smart IoT CO2, temperature, and humidity sensors with displays, in all their classrooms. These sensors are connected to the Halo Smart IoT Gateway, which updates the Analytics Platform with real-time readings and alerts. The schools can now monitor CO2 levels and room temperatures, ensuring proper ventilation and maintaining an optimal learning environment. The system not only provides visible displays within the classrooms but also sends alerts to the platform, enabling timely interventions to prevent CO2 levels from reaching harmful concentrations. The schools can save on energy costs by efficiently controlling classroom temperatures throughout the year. The Halo Smart Gateway can seamlessly connect up to 32 devices, making it suitable for larger buildings that require multiple sensors. This comprehensive solution allows for effective monitoring and control of classroom environments to ensure the well-being and academic performance of students.

Case study Smart IoT Solution for Fridge / Freezer Monitoring 20 October 2023 Implement monitoring solutions to prevent the loss of over £26,000 worth of stock due to temperature deviations in their fridges One of the Sewell Petrol Stations had recently lost over £26,000 of stock from its fridges due to the temperatures rising above the levels for safe food storage due to a fault with the fridge. Fridge and freezer monitoring is an essential part of refrigeration systems. It helps to maintain the temperature of the fridge or freezer, prevent food spoilage, and avoid other issues such as flooding. In response to the issue, Halo Smart IoT provided a comprehensive monitoring solution. They equipped all 13 petrol stations with Halo Smart IoT Fridge and Freezer monitors, connected to their IoT app via Halo Smart IoT Gateways. Halo Smart IoT Fridge/Freezer Sensors are used to monitor fridges and freezers, providing real-time temperature readings and alerts when temperatures exceed certain thresholds. Temperature alarms can be set to alert users when temperatures rise too high or drop too low. Additionally, our flood control systems can be installed in fridges and freezers to detect any leaks or water damage that may occur. Keeping a precise fridge temperature can be invaluable for a range of uses. Alarm system can be used to signal the temperatures dropping too low and posing a risk to the biological material inside. By monitoring fridges and freezers with Halo Smart IoT devices, businesses can ensure that their products are stored at optimal temperatures for maximum freshness and safety. This helps them save money on energy costs while also providing customers with quality products every time. Additionally, they adopted Halo Smart IoT Plugs to optimise electricity usage and reduce their carbon footprint. These plugs are now used to set timers on all electrical equipment in the stores – so that they can be switched off completely when they aren’t being used. This is now saving on the electricity usage and reducing the company’s carbon footprint. This success story showcases the benefits of IoT monitoring and control in the retail industry.

TEST Case study Smart IoT Energy Meter 20 October 2023 Tyrrell Systems is thrilled to exhibit at Smart Building Show 2023 in ExCel, London on 18-19 October 2023, offering you the opportunity to explore firsthand how our expertise in Master System Integration (MSI) seamlessly unifies a wide array of building systems. In 2021, we were contacted by an elderly couple residing in a retirement village in Oxford. They owned an electric vehicle and required a reliable and straightforward solution for charging it using the retirement village’s electricity supply. The catch was that they wanted to accurately monitor and calculate the associated costs, with the intention of not burdening their fellow residents with the additional electricity expenses. Understanding the need for a versatile solution that could be tailored to fit individual houses or an entire retirement village, we offered a perfect fix. We equipped them with a Halo Smart IoT Gateway and a Halo Smart IoT Energy Meter. The Energy Meter, designed to work seamlessly with their electric car charger, was easy to install by a professional electrician, ensuring that it could accommodate various setups and applications. The Halo Smart IoT Gateway further enhanced the system by wirelessly connecting the Energy Meter to the internet, thus enabling convenient and real-time tracking of energy consumption through our user-friendly Halo Smart IoT App. This versatility allowed the elderly couple to monitor their energy usage and related costs with ease, whether for a single home or a broader property portfolio. The result was an efficient and cost-effective solution that not only satisfied the specific requirements of the couple but also paved the way for future scalability. In the end, they could charge their electric vehicle without concerns about electricity costs, and the data collected allowed them to calculate and allocate expenses accurately without affecting their fellow residents.
