Built Environment
Create healthier, smarter commercial buildings
Monitor indoor air quality, temperature and humidity across commercial buildings with real-time environmental insight that helps improve occupant wellbeing, optimise energy performance and support sustainability, from the plant room to the boardroom.
Trusted by Balfour Beatty, the Environment Agency, Carmarthenshire County Council and leading estates teams.
Why Eltek
Healthier buildings, from the plant room to the boardroom
From offices and hospitals to universities and commercial estates, Eltek turns building conditions into actionable data, wired or wireless, on one connected platform. Monitor temperature, humidity, indoor air quality and CO₂ with alarms and escalation wherever you need to see them, so you can optimise comfort, performance and sustainability across every space.
Indoor air quality and comfort
Monitor temperature, humidity, CO₂ and indoor air quality across offices, hospitals, universities and commercial buildings, so occupant wellbeing is measured, not assumed.
Energy and sustainability insight
Long-term trend data helps optimise HVAC and energy performance and support sustainability and ESG reporting, from the plant room to the boardroom.
Wired and wireless
Deploy wireless sensors where cabling is not an option and wired sensors where a permanent connection suits, both on the same connected platform.
Real-time alarms and escalation
High and low thresholds aligned to your SOPs, time-delayed to cut nuisance alerts and escalated to the right team with time-stamped records.
One platform, many buildings
Consolidate a whole estate onto one connected solution, with secure cloud dashboards, trends and 21 CFR Part 11-compliant records from anywhere.

The platform
The Darca Solutions Suite
One connected platform for healthier, smarter buildings.
Darca Collect
Wireless GenII transmitters, wired sensors, probes and repeaters for indoor air quality, temperature and humidity across every space in the building.
Explore
Darca Connect
Hubs and SMS450 alarms keep multi-building estates connected and escalated, so the right team knows the moment conditions drift.
Explore
Darca Command
Secure cloud dashboards, trends and reporting, your building performance data wherever you need it, from the plant room to the boardroom.
ExploreProven in the built environment
From listed buildings to low-carbon homes
Eltek sensors monitor the built environment where wiring is not always an option, from archive stores and historic interiors to the Building for 2050 low-carbon housing project, where sensors across roughly 120 locations tracked temperature, humidity, CO₂, energy use and window-opening, relayed to the cloud through an SRV250 gateway.

ExploreFrequently asked questions
How do you monitor temperature and humidity across multiple building sites from one dashboard?
Eltek consolidates a whole estate onto one connected Darca platform: wireless GenII transmitters and wired sensors collect readings at each site, hubs and SMS450 alarms escalate any excursion to the right team, and Darca Command gives secure cloud dashboards, trends and reports from anywhere. Culture Perth and Kinross uses this approach to monitor five Scottish heritage sites, and Carmarthenshire County Council unified five museum sites onto one Eltek platform.
When should I choose wired over wireless environmental monitoring?
Wireless suits spaces where cabling is impractical or invasive, such as historic interiors or large obstructed floorplates, while wired sensors suit fixed installations needing a permanent, high-accuracy connection, such as process ovens or lab equipment. Eltek deploys both on the same connected Darca platform, so a site can mix wired and wireless sensing rather than choosing one architecture for the whole building.
