HVAC & Indoor Climate Monitoring for Smart Buildings
Remote HVAC Temperature and Humidity Monitoring for Smart Buildings
The SensMax SensGuard HVAC temperature and humidity monitoring system helps smart buildings, office complexes and commercial centers maintain a stable indoor climate, reduce energy consumption and detect HVAC failures at an early stage. Wireless sensors monitor temperature and humidity across multiple zones and floors, while the cloud platform provides real-time visibility and alerts.
What this solution does
SensGuard is a remote temperature and humidity monitoring system for commercial buildings with centralized heating, ventilation and air conditioning. Wireless sensors continuously measure temperature and humidity levels in offices, corridors, technical rooms and public areas and send readings to the cloud every 5 minutes.
Facility managers can use this data to verify that HVAC systems maintain the desired comfort level, balance heating and cooling between different zones and quickly spot areas where equipment is not working correctly. Early detection of deviations helps to reduce energy waste, avoid complaints from tenants and prevent costly damage caused by overheating, condensation or incorrect humidity.
Where you can use it
- Smart office buildings – monitoring comfort and HVAC operation across multiple floors and tenants.
- Shopping malls and commercial centers – supervising climate conditions in galleries, shops and common areas.
- Business centers and mixed-use buildings – controlling indoor climate in offices, lobbies and conference areas.
- Public buildings – municipalities, libraries, universities and other facilities with central HVAC systems.
- Technical rooms – HVAC plant rooms, air handling units, ducts and piping zones.

How the SensGuard HVAC monitoring system works
The system uses wireless temperature and humidity sensors installed in key zones of the building: offices, corridors, entrances, staircases, technical rooms and near HVAC equipment. Sensors read environmental parameters every 5 minutes and send data to the SensMax TCP LR X2 gateway, which transmits it to the SensGuard cloud platform.
For each sensor you can configure individual min/max temperature and humidity thresholds and allowed violation time. This allows the system to ignore short-term, insignificant fluctuations (for example, when doors are opened) and concentrate on real problems such as HVAC malfunction, stuck valves, blocked ducts or wrongly configured controllers.

One gateway can collect data from up to 250 sensors within a range of up to 150 m (extendable to 500 m with repeaters). The gateway has internal buffer memory to prevent data loss during Internet outages. Wireless sensors are battery-powered, with a battery lifetime of up to 5 years, and are suitable for indoor use or protected outdoor locations.
Hardware used in this solution
For HVAC and smart building projects, SensMax offers several wireless temperature and humidity sensors, including devices for standard rooms, technical zones and duct or pipe monitoring.
| Device | Type | Temperature range | Accuracy | Resolution | Battery / Power | Typical use |
|---|---|---|---|---|---|---|
| MCP9800 wireless temperature sensor | Waterproof sensor | −20°C…+55°C | ±0.5°C | 0.1°C | up to 5 years | General indoor areas: offices, corridors, lobbies and meeting rooms. |
| ENS210 wireless temperature & humidity sensor | Temperature & humidity sensor | −20°C…+55°C / 0–100% RH | ±0.5°C / ±3.5% RH | 0.1°C | up to 5 years | Comfort monitoring in smart buildings and malls, including humidity control. |
| DS18B20 probe-type wireless temperature sensor | Probe sensor | −30°C…+120°C | ±0.5°C | 0.1°C | up to 5 years | HVAC ducts, pipes and other technical locations where the probe must be mounted on or inside equipment. |
| PT100 wireless temperature sensor with probe | High-range probe sensor | −50°C…+200°C | ±0.2°C | 0.1°C | up to 5 years | Monitoring supply/return lines, heat exchangers and other HVAC components. |
Energy efficiency and comfort
Continuous monitoring of indoor climate helps building owners and facility managers balance heating and cooling between zones, avoid overheating and unnecessary energy consumption and verify that HVAC equipment works as expected. Historical data reveals patterns such as constant overcooling of certain rooms or high temperatures in specific areas, helping to fine-tune HVAC settings.
By keeping temperature and humidity within recommended ranges, you improve comfort for occupants, reduce complaints and extend the lifetime of building materials and equipment.
Recommended configuration for a typical smart building
- 10–80 wireless sensors depending on building size, number of floors and monitored zones.
- 1–3 SensMax TCP LR X2 gateways with LAN/Internet connection.
- SensGuard cloud access for facility managers, technical staff and building owners.
- Automatic notifications via e-mail and Telegram messenger for on-duty personnel.
SensGuard cloud software for smart buildings and HVAC
The SensGuard online portal provides a complete overview of climate conditions in the building. Users can:
- see real-time temperature and humidity values for each room, floor and technical area;
- upload a building or floor map and place sensors on it for quick identification of problem zones;
- set individual min/max thresholds and allowed violation times for each sensor;
- configure user-specific notification rules via e-mail and Telegram messenger;
- analyse long-term temperature and humidity trends to optimize HVAC operation and energy usage;
- export data in CSV or PDF format for internal reports and maintenance documentation.
