Smart Office Heat Zone Monitoring
A leading corporate office in Pune faced challenges in maintaining consistent air quality and thermal comfort across their workspace. Despite modern central AC systems, certain areas experienced hot or cold zones, leading to uneven cooling, higher energy bills, and employee discomfort.
The organization wanted a data-driven solution to:
Monitor indoor air quality (AQI) continuously.
Detect heat zones in real time.
Optimize central AC airflow and energy usage.
Improve employee comfort and workplace productivity.
To address these goals, Macnman Technologies deployed a LoRaWAN-based IoT monitoring network, providing actionable insights for efficient climate control and cost savings.
Problem Identified: Poor Air Quality & Worker Discomfort
Large corporate offices often struggle with uneven temperature distribution and poor air quality, which can affect employee comfort, productivity, and energy efficiency
Hot & Cold Zones
Certain office areas experienced inconsistent temperatures, affecting employee comfort and productivity.
Employee Discomfort

Temperature and Humidity Sensors
Strategically placed to map thermal zones, identify hot/cold spots, and guide HVAC optimization.
MacSet Controllers
Used to collect sensor data, manage Andon lights, and communicate over LoRaWAN for visual status indicators.
Challenges: From Data Gaps to Reliable Indoor Intelligence
Signal Interference in Office Layouts
LoRaWAN signals faced interference from glass partitions, metallic ducts, and dense office structures we optimized gateway placement and antenna gain to maintain uninterrupted data flow.
Sensor Accuracy in Dynamic Environments
Synchronizing the MacSet Andon lights with sensor thresholds required careful configuration to avoid false alerts and ensure timely staff response.
Integration with Facility Systems
Bringing LoRa-based sensors into an existing building automation ecosystem required custom mapping and API configurations for seamless dashboard integration.
Employee Awareness and Data Interpretation
We trained facility teams to interpret heat map analytics and AQI trends effectively — turning data into actionable energy savings.
