EnviroSaudi is a Scentroid HW20 HVAC Warden supplier in Saudi Arabia, providing the configurable indoor-air monitoring device that makes sensor data available to facility and ventilation systems. Scentroid’s current product page lists BACnet, Modbus, current and voltage outputs, and EnviroSaudi, an authorized Scentroid distributor, prepares the Saudi product and integration scope.

A successful deployment requires more than protocol names: the sensors, data points, controls architecture, thresholds, ownership and safe response logic must be defined. Configuration, availability and lead time are confirmed in each quotation.
Select the measurements before the interface
The HW20 supports up to 10 sensors according to the manufacturer. Listed sensor types include photoionisation detection, non-dispersive infrared, electrochemical and laser particulate sensing, together with temperature, relative humidity and barometric pressure. The proposed set follows the building question. Carbon dioxide may help assess occupied-zone ventilation patterns; particles can show changes associated with outdoor ingress or indoor activity; and a selected gas sensor may support a defined industrial or operational concern.
“Up to 10” is a capacity statement, not a promise that every parameter is included. The schedule identifies each sensor, range, unit, expected background, possible interference and reason for inclusion. It also states whether the result is for trend visibility, alerting, investigation or an input to a separately engineered controls sequence. Where the wider need is to understand zones and response plans, see indoor air-quality and ventilation monitoring.
Scentroid HW20 HVAC Warden supplier: station features
Scentroid lists an approximate one-second sampling rate and one or two sampling ports. The current communications table shows 3G/4G and LAN as default and Wi-Fi as optional. It also lists 64 GB SD storage, an onboard server, SIMS3 connectivity and a seven-inch touchscreen. These specifications are confirmed for the exact hardware revision and order because the field design depends on the data route, local access and retention expectations.
For calibration, the manufacturer lists manual calibration using calibration gas and an optional automatic arrangement using built-in calibration gas. The operating plan covers access, checks, calibration-gas responsibility, consumables where applicable, recordkeeping and response to a sensor fault. Data integration does not remove the need for calibration, maintenance and spare-parts planning.
BACnet and Modbus need an integration design
Protocol availability is useful, but it does not define the final connection. The controls consultant or system integrator confirms:
- the selected physical and network interface, point list and addressing
- units, scaling and update rate
- quality/status flags, alarm handling and loss-of-signal behaviour
- the equivalent definition for current and voltage outputs
Network segmentation, credentials, remote access, time synchronisation and change control belong in the cybersecurity and commissioning plan.
Most importantly, a sensor reading must not drive ventilation equipment until the controls designer has approved the sequence. The design needs limits, delays, fallback states, equipment interlocks, override authority and verification tests. EnviroSaudi coordinates the monitor-side data and documentation through environmental monitor integration services, while the responsible controls parties retain ownership of plant logic and life-safety boundaries. Equipment supply does not replace the engineering approval, permit or regulatory decision that applies to your project.
Commissioning proves the complete path rather than only showing that a value appears on a screen:
- Inject or simulate known states.
- Verify the displayed value and unit.
- Check status flags and alarms.
- Interrupt the connection and observe the agreed fallback.
- Record the result.
The handover preserves the approved point list, configuration backups, test sheets and named owners for later changes. That evidence reduces the risk of an apparently live connection carrying the wrong scale, timestamp or quality state.
Saudi facility applications and delivery scope
The HW20 is available for projects across Saudi Arabia, including Dammam, Jubail and Riyadh, for office portfolios, airports, healthcare or education facilities, hospitality, malls, transport assets and selected occupied industrial spaces. Conditions vary: a Riyadh facility may contend with dust and large indoor-outdoor temperature differences; a Jeddah site may add high humidity and coastal exposure; and an Eastern Province industrial building may require careful separation of comfort monitoring from occupational-safety instrumentation. The room, sample location and sensor technology must fit the use.
An EnviroSaudi proposal includes:
- the sensor and range schedule, location plan and sampling arrangement
- mounting and power requirements, communications selection and point-list brief
- an alarm workshop, commissioning checks, platform scope, training and maintenance plan
Please provide mechanical and controls drawings, room uses, operating hours, existing protocols, IT requirements and the intended action for each parameter.
Frequently asked questions
Who is the Scentroid HW20 HVAC Warden supplier in Saudi Arabia?
EnviroSaudi supplies the Scentroid HW20 HVAC Warden for projects across Saudi Arabia and prepares the configuration, integration scope and quotation for each project.
Which parameters can the HW20 monitor?
The manufacturer lists PID, NDIR, electrochemical and laser-particle sensor types plus temperature, relative humidity and barometric pressure, with capacity for up to 10 sensors. The exact parameter combination and ranges are confirmed for the order.
Does the HW20 support BACnet and Modbus, and can it connect to an existing BMS?
Yes. Scentroid’s current HW20 page lists BACnet and Modbus compatibility, as well as current and voltage outputs. Connection to an existing BMS needs a compatible interface, an agreed point list, security controls, fault behaviour and witnessed functional testing.
Can sensor readings automatically change ventilation?
They can be made available to a separately designed control sequence, but automatic action is not assumed. A controls professional defines thresholds, delays, limits, overrides, interlocks and safe fallback behaviour and then verifies the complete sequence.
What affects the cost of an HW20 supply and integration?
Cost depends on the sensor and range schedule, sampling ports, communications, point-list and integration scope, platform access, commissioning and training. Provide room and air-system information, target parameters, controls diagrams and network requirements to start a proposal.
How long does HW20 delivery take?
Lead time depends on the configuration, integration scope, site readiness and commissioning, and is confirmed in the quotation.
How do I choose an HW20 for my building, and what are its limitations?
Start from the measurements the building needs, then review sensor cross-sensitivity, range, environmental limits, sampling location, calibration method and network resilience. The HW20 does not replace purpose-specific life-safety detection, occupational-exposure assessment or a prescribed reference method.
EnviroSaudi serves projects across Saudi Arabia, including Dammam, Al Khobar, Jubail, Riyadh, Jeddah, NEOM and Qiddiya.
