Environmental Monitoring — know the conditions before they become a problem.

Temperature, humidity, CO2, air quality, leaks and energy — monitored two ways: wireless battery sensors for sites with no infrastructure, and wired HW Group units where power and networking already exist. Alerts to your phone either way, staged and configured in Galway.

The Essentials

What Is Environmental Monitoring?

Environmental monitoring uses sensors to continuously track the conditions a site depends on — temperature, humidity, CO2 and air quality, water leaks, energy use and occupancy — and alerts the right person the moment a threshold is crossed, instead of someone discovering the problem hours later. It protects server rooms from heat, cold stores and pharmacies from spoilage, buildings from leaks, and energy budgets from waste. TITAN IoT supplies both wireless battery sensors and wired monitoring units in Ireland, configured before they ship.

Two Architectures

Wireless Battery Sensors, or Wired Powered Units?

One question decides it: is there power and a network where you need to measure? We supply both architectures — and plenty of sites use a mix.

Wireless Battery Sensors

Milesight LoRaWAN sensors run for years on battery and transmit through walls to a gateway — no wiring, no Wi-Fi, no mains at the measurement point. Fit one in minutes, add more as you go.

Choose when: there’s no power or network where you’re measuring, sensors are spread across a building or site, or you’re retrofitting without cabling — storage units, cold rooms, classrooms, offices, farms.

Wired, Powered Monitoring Units

They connect the sensors you already have. The HW Group Perseus reads third-party instruments directly — 4-20mA transmitters such as Druck pressure sensors, Modbus devices, meter pulses, dry contacts — and brings them onto one dashboard with one alerting policy. Nothing gets ripped out.

Around that, plug-in probes add temperature, humidity, CO2 and leak sensing — on LAN or PoE, no batteries ever, with relays to switch things and LTE backup with SMS when the network fails.

Choose when: power and networking exist at the point of measurement — server and comms rooms, plant rooms, panels, warehouses — or existing sensors and meters need to come online.

The Range

The Sensors and Units We Deploy

Six cover most Irish projects — the full range, including the TS101 insertion probe, WS202 motion sensor, rack-mount Perseus 150 and Modbus probes, the budget STE2 LITE, the Ares 12 LTE unit for sites with no network at all, and the WLD2 leak detector, is in the grid below.

Milesight CT101 LoRaWAN smart current transformer for energy monitoring Ireland

CT101 — Energy Monitoring

A clip-on current transformer that reports circuit consumption wirelessly — sub-meter plant, distribution boards and equipment without an electrician rewiring the panel. The energy-audit enabler.

Wired — HW Group

HW Group Perseus 145 LAN LTE monitoring unit with sensor ports Modbus and relays

Perseus 145 — Site Monitor

The site brain: LAN with LTE backup, four probe ports, Modbus RTU for instruments already on site, leak-cable zone, inputs and relays — plus a built-in SMS gateway so alerts get through even when the network doesn’t.

Irish Applications

What Irish Sites Monitor

Server & Comms Rooms

Heat kills hardware quietly — a wired unit on the rack watches temperature, power presence and door state, and rings a phone before the room cooks.

STE2 · Perseus 145 · Perseus 150

Cold Chain & Pharmacy

Fridges, cold rooms and vaccine stores with continuous records and instant excursion alerts — compliance evidence generated automatically.

TS101 · EM320-TH · STE2 with probes

Self-Storage & Warehousing

Humidity and leak monitoring across units and floors without cabling — one gateway, battery sensors everywhere, damp caught before customers’ goods are.

EM300 series · leak sensors · UG65 gateway

Energy & Carbon Reporting

Clip-on CTs and meter pulse readers turn circuits into data — the measured baseline energy audits and public-sector carbon reporting need.

CT101 · pulse readers · IoT Factory platform

Machine & Plant Rooms

The Perseus concentrates what’s already there — third-party 4-20mA transmitters, Modbus instruments, fault contacts — and adds probes, alerts and relays around them. Existing kit comes online, nothing replaced.

Agri & Greenhouse

Soil, climate and storage conditions on battery sensors that live outdoors for years — with a solar gateway option where there’s no power at all.

Complete the System

Sensors Need a Network and a Home

Wireless sensors report through a LoRaWAN gateway — one per building or site covers hundreds of sensors, and we pre-pair everything before dispatch. Wired units connect straight to your LAN or PoE.

The readings land where you want them: the IoT Factory platform with dashboards, alerts and reports; HW Group’s SensDesk portal; your own system by API — or a building IoT gateway bridges it all into the BMS. Full solution, device only, or just the data: no lock-in on any path.

FAQ

Environmental Monitoring Questions, Answered

What is environmental monitoring?

Environmental monitoring uses sensors to continuously track the conditions a site depends on — temperature, humidity, CO2 and air quality, water leaks, energy use and occupancy — and alerts the right person the moment a threshold is crossed. Instead of discovering a failed fridge or an overheated server room after the damage, you get a phone alert while there’s still time to act.

Wired or wireless — which do I need?

It depends on one thing: whether power and a network exist where you need to measure. If they do — server rooms, plant rooms, panels — a wired unit with plug-in probes is simplest and never needs a battery. If they don’t — storage units, cold rooms, spread-out buildings, farms — battery-powered wireless sensors deploy in minutes without any cabling. Many Irish sites run both: wired in the technical rooms, wireless everywhere else.

Do the sensors need Wi-Fi?

No. Wireless sensors use LoRaWAN — long-range radio to a gateway, through walls and floors, with multi-year battery life; the gateway uses your network or its own 4G. Wired units use Ethernet or PoE, with Wi-Fi and LTE backup options. Nothing depends on consumer Wi-Fi reaching a cold room or a storage unit.

How do the alerts reach me?

However suits your team: app notification, email, SMS or an escalating voice call for the alarms that must wake someone. Thresholds, delays and escalation chains are set up before dispatch, and the HW Group units can send SMS through their own built-in LTE modem even when the site network is down.

Can I connect sensors and meters I already have?

Yes — that’s a core job of the wired units. The Perseus reads what’s already installed — 4-20mA transmitters such as Druck pressure sensors, Modbus RTU instruments, 0-30A current signals, dry contacts and meter pulses — concentrates them alongside its own probes, and puts the lot on one dashboard with one alerting policy. Existing kit comes online without being replaced.

Why monitor CO2 and air quality in buildings?

CO2 is the practical proxy for ventilation: rising levels mean stale air, drowsiness and infection risk in classrooms, offices and healthcare settings. Continuous monitoring shows which rooms need ventilation action and proves the building is performing — increasingly expected in public-sector and workplace standards. Battery sensors with displays make it visible room by room without any wiring.
