Smart LoRaWAN Air Quality Monitoring
Bajaj’s corporate office needed real-time monitoring of air quality and temperature to improve employee comfort and energy efficiency.
Macnman Technologies deployed a LoRaWAN-based IoT network to track CO₂, PM2.5, humidity, and temperature, feeding data into the central building management system for optimized HVAC control, healthier workspaces, and energy savings.
Problems: Poor Indoor Air Quality & Energy Inefficiency
Bajaj’s corporate office struggled with maintaining healthy indoor air quality (AQI) and optimal temperature across multiple floors, affecting both employee well-being and energy efficiency. Key challenges included:
Uneven Temperature Zones
Hot and cold spots caused employee discomfort and reduced workplace productivity.
Lack of Real-Time AQI Monitoring
CO₂, PM2.5, and humidity levels were invisible without IoT-based sensors, delaying corrective actions.
Inefficient HVAC Operation
Central AC ran at full capacity unnecessarily, driving up energy costs and carbon footprint.
Delayed Facility Response
Without continuous data, maintenance and airflow adjustments were reactive rather than proactive.
