What they care about: uptime and compliance. Many facilities integrate heat monitoring into their broader HSE (Health, Safety, Environment) dashboards, reducing the need for manual logs.

 

Military and Defense

Defense forces use a mix of portable and wearable monitors for training and active deployments, especially in desert or jungle environments. For them, biometric integration is critical—they’re tracking not just ambient heat, but also soldier hydration levels, core body temperature, and exertion.

Some militaries now deploy AI-assisted platforms to adjust training schedules or send preemptive hydration alerts based on predicted stress loads.

 

Sports & Event Management

This segment is gaining visibility after several athletes collapsed during international tournaments due to heat. Sports federations and event planners now use handheld and portable heat monitors for:

• Checking field or court conditions

• Timing training sessions

• Setting game-day protocols

Several marathons now employ heat stress monitors along race routes, paired with medical tents and hydration stations.

 

Agriculture and Forestry

Often underrepresented in discussions, this sector faces serious exposure—especially for seasonal and migrant laborers . Portable and wearable monitors are being piloted in vineyards, orchards, and livestock operations.

Some large agri -cooperatives are experimenting with solar-powered monitoring systems in remote locations, synced with SMS alert systems for field supervisors.

 

Use Case: Smart Safety Program in an Australian Mining Operation

A major mining company operating in Western Australia faced a growing number of heat-related near-miss incidents. Rather than wait for a regulatory fine or injury, the safety team partnered with a heat stress monitor vendor to roll out a hybrid system : fixed monitors in underground shafts, wearable sensors for all drill operators, and a cloud dashboard monitored from the control center .

The system flagged unsafe conditions in a central shaft mid-shift. Operators were pulled from the zone within minutes. According to the safety lead, “We didn’t just avoid a medical emergency—we avoided a shutdown. One hour of downtime would’ve cost us six figures.”

After three months, incidents dropped by 42%, and the ROI was clear. Leadership approved a full rollout across multiple sites.
