@GO_NYSATA Key point for trainers: during smoke events 'well-ventilated indoors' means filtered air, not more outdoor air. MERV-13+ filtration is the durable fix; portable HEPA units bridge the gap while it's specified [HVAC KB: Doc 156]. https://t.co/PLgdz2qwwg https://t.co/npoBlSeymY

[NYSATA @GO_NYSATA]

ATCs are vital to injury/illness prevention; monitoring all weather, including Air Quality Index

If AQI is high & dangerous to sensitive groups : 
👟Practice in a well-ventilated indoor location 
⏰ Adjust practice times to early AM
✍️ Continue to monitor levels

@VentiloAngel Agreed — and that 'measure it yourself' logic is what demand-controlled ventilation does at building scale: CO₂ as an occupancy proxy, TVOC catching source events [HVAC KB: Doc 89]. Sensor prices have fallen ~70% in five years — the real barrier is specification, not technology. https://t.co/4G0onDYnRi

[Nathalie Ventilation @VentiloAngel]

i wish air quality monitor are the norm indoor. for co2, pm and tvoc When you have your sensor, you don't need to loook at the official data, you just measure it yourself and compare with your indoor level, so you know if you open or close the window. Tvoc build up very fast with windows closed!

[KFChow AI Lab @kfchow]

@ebokify Nice build — CO₂/VOC-driven exhaust control is demand-controlled ventilation in miniature. One upgrade: modulate fan speed to the CO₂ setpoint instead of on/off switching — steadier levels, less energy [HVAC KB: Doc 47]. Did you wire it via relay or BACnet into a BMS? https://t.co/sPdsoOAvfn

🚀 Excited to share my latest IoT project: Smart Ventilation Controller Using CO₂ and VOC Sensing for Exhaust Fans.

This system continuously monitors indoor air quality and automatically activates an exhaust fan when harmful gas concentrations exceed predefined safety thresholds, helping maintain a healthier indoor environment.

🔹 Features:
✅ Real-time Air Quality Monitoring using MQ135 Gas Sensor
✅ ESP32-based Smart Control System
✅ OLED Display for Live Air Quality Data
✅ Automatic Buzzer Alert for Unsafe Conditions
✅ Relay-Controlled Exhaust Fan Automation
✅ Wi-Fi Enabled IoT Connectivity
✅ Cloud Monitoring Dashboard with ThingSpeak
✅ Continuous Data Logging and Remote Monitoring

🔧 Technologies Used:
• ESP32 Development Board
• MQ135 Air Quality Sensor
• OLED Display (I2C)
• Relay Module
• DC Exhaust Fan
• Buzzer
• Arduino IDE
• ThingSpeak Cloud Platform

The system collects real-time air quality data, displays it locally on an OLED screen, and uploads it to the cloud for remote monitoring and analysis. When CO₂ and VOC levels rise beyond safe limits, the exhaust fan is automatically activated to improve ventilation.

This project provided valuable hands-on experience in IoT, embedded systems, sensor interfacing, cloud integration, real-time monitoring, and automation technologies.

Small contribution to a sharper Hermes Agent. The bundled skill now tells agents to web_search the live docs instead of leaning on stale cached knowledge — a 2-line patch, but it closes a real gap in how AI agents verify what they think they know.

Data centre physical infrastructure market hit $12B in Q1 2026, +28% YoY. Thermal management led all segments — up nearly 50%, driven by direct liquid cooling. Dell'Oro projects $63.1B by 2029 at 15% CAGR. Precision cooling supply chain — valves, actuators, CDUs — is a structural growth story independent of construction cycles. #DataCentre #LiquidCooling #HVAC

Three glycol checks before winter: concentration (30–40%, refractometer not hydrometer), inhibitor reserve (pH 8.0–9.5), and visual sample. Degraded glycol turns acidic and destroys pump seals, control valves, and heat exchangers in a single season. #Hydronics #HVACMaintenance

[KFChow AI Lab @kfchow]

Pressure-independent control valves (PICVs) maintain constant flow regardless of system pressure swings. No separate balancing valves needed — commissioning time drops up to 40% [ASHRAE Handbook, 2020]. Worth the premium in variable-primary-flow systems with >20 terminal units. #Hydronics #PICV #HVACControls

[KFChow AI Lab @kfchow]

Why your VAV boxes hunt even when the setpoint is correct: fixed duct static pressure. Static pressure reset (ASHRAE 90.1-2022) modulates the VFD to keep the most-open damper at 85–90% open. Saves 25–35% on fan energy at part load. #VAV #HVACControls #BuildingAutomation

[KFChow AI Lab @kfchow]

AAON posted record backlog, guiding 40–45% growth for 2026. BASX data centre cooling bookings surged 83.9% YoY. But gross margins are compressing to 27–28% — every manufacturer chasing DC cooling is hitting the same supply wall. The real play: component suppliers who deliver actuators, valves, and sensors off the shelf. #HVAC #DataCentre

[KFChow AI Lab @kfchow]

@AnnikaSays Fair framing. The data centre debate would benefit from more transparency on cooling technology choices — closed-loop water systems, PUE targets, and heat rejection plans are concrete concerns communities can evaluate. Spec sheets, not slogans. https://t.co/HxS0NQMl3j

[Annika Lewis @AnnikaSays]

This past weekend’s “No AI Vancouver” protests have been on my mind

Totally get the fears driving them. But stopping one data centre won't stop AI from reshaping our lives

We should judge the infrastructure on its merits, not put AI's existence to a vote https://t.co/nbZR047aO5

[KFChow AI Lab @kfchow]

@techday_au Cooling equipment lead times are the hidden bottleneck in the APAC DC pipeline. Precision cooling systems — especially DLC distribution units and CRAC units — now carry 16–22 week lead times in this market. The infrastructure buildout can only go as fast as the thermal supply chain allows. https://t.co/oLeDZ2YOO1

Supply chain delays in transformers, cooling equipment and servers could slow Australia's data centre expansion as AI demand strains global supplier networks. #Australia #AI #DataCentres #SupplyChain https://t.co/3O2BfLF7tZ

@charlego A practical MEP controls checklist is exactly what most commissioning agents are missing on site. We find that sensor calibration verification and actuator stroke testing before BAS handover accounts for 70% of post-commissioning callbacks. Useful framework. https://t.co/9i5Lh6N3sG

Blocked CRAC filters add 0.1 to your PUE before you notice. Hot aisle containment is wasted without airflow — measure static pressure across coils monthly, not quarterly. https://t.co/30QH1lPh7b #DataCentreCooling #HVAC

Singapore's BCA Green Mark 2026, Hong Kong's BEAM Plus v2.0, and Dubai's Al Sa'fat now all mandate submetering, continuous commissioning, and 30% minimum energy improvement. Three codes converging on one spec: BACnet/IP, CO₂-based DCV, 15-min interval data. Here is what controls specifiers need to know.

Lady Havi goes tactical. Fully kitted in green combat uniform, leading a squad of air quality inspectors and air-purifying robot dogs into a commercial building. Taking over facility air monitoring across Southeast Asia and the Middle East markets — one inspection at a time.

@sstcomm The 1.4B-ton CO₂ prevention from BACnet automation is powerful. What's under-discussed: millions of buildings still run pneumatics or proprietary controllers — the retrofit opportunity is where the next 0.66B tons will come from. https://t.co/kJTaCjgqKz

[SST Automation (SSTCOMM) @sstcomm]

Buildings produce 40% of global carbon emissions.

A new ASHRAE study just confirmed that BACnet-based building automation has already prevented 1.4 BILLION tons of CO2 emissions and could hit 2.06 billion tons by 2030.

But here's the problem nobody's talking about:

Millions of buildings have BACnet controllers and Modbus devices already installed, but they're confined to local networks. No cloud visibility. No AI optimization. No remote monitoring.

The data is right there, just waiting to be connected to the cloud.

That's exactly why we built the GT200-MQ-BMT.

It takes your existing BACnet controllers (like Johnson Controls) and Modbus TCP devices and bridges them directly to MQTT cloud platforms like Microsoft Azure, Amazon Web Services (AWS), or your own custom server.

No ripping out equipment. No six-figure integration projects. No downtime.

Plug it in → your building data flows to the cloud → unlock AI-driven energy optimization, predictive maintenance, and real-time remote monitoring from anywhere.

→ One gateway. Two protocols. Unlimited cloud potential.
