Gas Detection

One detector body. Thirty-plus gases. Your IoT platform.

Fixed gas detection usually means a separate vendor, a separate panel, and a separate pane of glass. Our detector platform puts toxic, combustible, and asphyxiant gas monitoring on the same stack as every other sensor you run: a replaceable sensing cell sets the gas, and the readings land in the same cloud, the same alerts, and the same branded apps.

Who this is for

Three kinds of operators.

The same detector platform serves a poultry house, a pumping station, and a white-label safety product. What changes is the sensing cell and the integration depth.

Livestock and agriculture operators

Ammonia in poultry houses, CO2 in greenhouses, methane around manure digesters, oxygen in controlled-atmosphere storage. You need fixed detection wired into the same platform that already runs your climate and process sensors, with relays that stage fans before a reading becomes a loss.

Industrial and municipal operators

Wastewater plants, pumping stations, chemical storage, fuel handling. You need continuous toxic and combustible gas monitoring with local alarm relays, 4-20 mA into your existing panels, and a cloud layer that logs every excursion for audits.

OEMs and integrators

You are building a safety or environmental product and need gas detection as a component: one detector platform covering dozens of gases, your brand on the dashboard and mobile app, and a supply chain handled for you.

Gas selection

One body, a sensing cell per gas.

Every detector shares the same flameproof housing, LCD, relays, and outputs. The cell inside sets the target gas, range, and resolution. Selectable ranges below; the right range for your application is part of the scoping conversation.

How it connects

Local safety, cloud visibility, same product.

Gas detection has a hard requirement most sensors do not: the alarm must work even when the network does not. The platform layers cloud on top of local interlocks instead of replacing them.

Local interlock via relays

Two configurable alarm relays per detector, normally open dry contacts. Fans, solenoids, and sirens trip locally with no network dependency.

4-20 mA into existing panels

The analog loop feeds PLCs, DCS, and legacy alarm panels directly. The detector drops into an installed base without replacing it.

RS485 Modbus into our controllers

Digital readings stream over Modbus-RTU into our industrial IoT controllers, joining every other sensor on the site: climate, level, water quality, energy.

Cloud alerts, logs, and API

Concentration curves, threshold alerts to the right person by severity and shift, exportable excursion logs, and REST plus MQTT APIs for your MES or reporting stack.

Why OmnIoT

Detection as part of the platform, not another silo.

A gas reading is most useful next to the rest of the site's data: ammonia beside house temperature and ventilation state, methane beside digester process data, oxygen beside cold-room door events. Because the detectors join our controllers over the same Modbus bus as every other sensor, that context comes built in: one dashboard, one alert routing policy, one API, one brand on the app your operators open.

FAQ

Gas detection questions.

How does one detector platform cover this many gases?

The detector body, display, outputs, and enclosure are identical across the family; the sensing cell inside sets the target gas and range. That means one spare-parts inventory, one integration, and one wiring standard across every gas point on a site. Cells are replaceable at end of life without changing the installation.

How do the detectors connect to the OmnIoT platform?

Each detector outputs 4-20 mA, RS485 Modbus-RTU, and two alarm relays in parallel. The Modbus output connects to our industrial IoT controllers alongside any other sensor on the site, streaming to the cloud for dashboards, alerts, and APIs. The analog loop and relays serve existing panels and local interlocks at the same time.

Do the alarm relays depend on the network?

No. The two relays are driven locally by the detector against its configured set points. Ventilation, shutoff, and sirens trip even if connectivity is down; the cloud layer adds logging, remote visibility, and escalation on top.

Can gas detection be part of a white-label product?

Yes. The detection layer rides the same multi-tenant platform as the rest of the stack: your brand on the cloud dashboard and the mobile apps, your customers in your tenant, quoted as part of an ODM engagement.

Are the detectors suitable for hazardous areas?

The detectors are built in flameproof aluminium enclosures designed for hazardous-area installation, with IP65 sealing for washdown and outdoor sites. Certification documentation for your market and installation class is scoped per engagement.

What does a gas detection engagement look like?

Quoted per scope, like every engagement: gas points, target gases and ranges, panel integration depth, and cloud tenancy. Pilots typically start with a handful of detectors on one site before scaling.
