Heat index is invisible. HeatAlert Connect™ makes it visible.
A thermometer can't tell you when your facility becomes dangerous. HeatAlert Connect™ monitors temperature and humidity 24/7, calculates the real OSHA heat index every 10 seconds, and alerts you before workers start collapsing. Launching publicly in 2027 — join the waitlist to reserve early-access pricing.
Three reasons the number on your thermostat isn't the number OSHA cares about.
Air temperature alone doesn't reflect what heat actually feels like on a worker's body. Heat index — the OSHA-recognized measurement — combines temperature and humidity into a single number that reflects real physiological load.
Humidity changes everything
88°F at 50% humidity feels like 91°F. Same 88°F at 75% humidity feels like 103°F — the OSHA danger threshold. Your thermostat reads the same number in both scenarios.
Direct sun adds ~15°F
NOAA notes that direct sunlight adds up to 15°F to the perceived heat index above the shaded value. Workers on a loading dock, tarmac, or open jobsite are hotter than a wall-mounted thermostat suggests.
Ventilation gaps go unnoticed
A stopped fan, a blocked vent, or humidity buildup in an enclosed area can push conditions into danger territory in minutes. Continuous measurement catches it. Occasional walk-throughs don't.
Install in 10 minutes. Monitor from anywhere.
HeatAlert Connect™ plugs into any 110V outlet, connects to Wi-Fi via a captive portal setup, and starts reading heat index within minutes. Every reading flows to your cloud dashboard and triggers email alerts at OSHA thresholds.
Plug in
Mount the unit on a wall near a standard 110V outlet. Sensor probe extends up to 10 feet to reach the measurement location.
Connect Wi-Fi
Open your phone, join the "HeatAlert-Setup" network, enter your Wi-Fi credentials. Takes under 2 minutes. No app required.
Pair to dashboard
Enter the 6-digit pairing code from the device screen at monitor.heatalert.com. Your unit appears in your dashboard within seconds.
Monitor 24/7
Heat index calculated every 10 seconds. Email alerts fire at OSHA thresholds. All data logged for OSHA-defensible documentation.
One dashboard. Every site. Every reading. Every alert.
Whether you have one HeatAlert Connect™ unit or a hundred across multiple facilities, everything lives in one place. Real-time readings, historical trends, alert history, and compliance-ready CSV exports.
Dashboard access included with every HeatAlert Connect™ unit at launch. Standard subscription tiers announced alongside the public product in 2027.
Facilities where compliance documentation matters as much as the reading itself.
HeatAlert Connect™ is built for organizations that need continuous heat index measurement, defensible documentation for OSHA inspections, and centralized visibility across multiple sites. Six environments where these three things are non-negotiable.
Distribution & Warehousing
Multi-site logistics operations where each DC has different ambient conditions. Central EHS team needs one view of every facility.
Manufacturing & Industrial
Foundries, process plants, assembly floors where radiant heat + humidity spikes make conditions harder to predict than temperature alone suggests.
Construction & Jobsites
Mobile crews across changing sites. Real-time email alerts to superintendents and safety officers when conditions cross OSHA thresholds.
Agriculture & Packing
Seasonal harvest operations, packing sheds, equipment buildings. Automatic logging simplifies workers' comp claim defense and OSHA reporting.
Utilities & Energy
Substations, pump stations, control rooms. Isolated workers in enclosed spaces need EHS visibility when direct supervision isn't practical.
Athletic & School Facilities
Field houses, weight rooms, athletic complexes. Duty of care documentation for athletes, coaches, and grounds crews during heat waves.
Built for compliance-grade measurement.
HeatAlert Connect™ is engineered to meet OSHA workplace heat measurement standards using the NOAA/OSHA Rothfusz heat index calculation. Preliminary specifications — final specs published at launch.
