Environmental sensors in wearable devices have practical applications in outdoor activities, agriculture, and industrial sectors. Below are examples of specific use cases along with the names of actual products that incorporate these technologies.

1. Applications in Hiking and Outdoor Activities
 a. Altitude and Barometric Pressure Sensors

• Product Example: Garmin Fenix 7
  • Functionality: This smartwatch is equipped with an altimeter and barometric pressure sensor to track elevation and forecast weather changes.
  • Use Case: Hikers can monitor altitude gains and receive alerts about pressure drops, which may signal approaching storms or altitude sickness risks.

b. Weather Prediction and Alerts

• Product Example: Suunto 9 Baro
  • Functionality: Incorporates barometric and temperature sensors for weather trend tracking and storm alarms.
  • Use Case: Provides real-time weather updates to hikers, helping them plan safer routes or take shelter during sudden weather changes.

c. UV and Light Sensors

• Product Example: L’Oréal My Skin Track UV
  • Functionality: A clip-on wearable UV sensor that tracks real-time sun exposure and syncs with a smartphone app for detailed reports.
  • Use Case: Advises hikers on sun protection measures, such as applying sunscreen or wearing hats during high UV exposure.

d. Oxygen and Air Quality Sensors

• Product Example: Garmin Descent Mk2i
  • Functionality: Features a pulse oximeter to measure blood oxygen levels and is particularly useful for high-altitude activities.
  • Use Case: Alerts mountaineers to potential hypoxia risks and helps them pace themselves effectively at high altitudes.

2. Applications in Agriculture

a. Soil Condition Monitoring

• Product Example: Arable Mark 2
  • Functionality: While primarily a field sensor, it can be used alongside wearable devices to relay soil data such as moisture, temperature, and sunlight conditions to farmers.
  • Use Case: Farmers receive alerts on their smartwatches (e.g., Apple Watch or Samsung Galaxy Watch Active) for optimal irrigation timing.

b. Atmospheric Environment Monitoring

• Product Example: Kestrel 5400AG
  • Functionality: A handheld weather meter that measures temperature, humidity, and wind speed. When paired with mobile apps, farmers can wear devices to receive updates.
  • Use Case: Farmers wearing smart glasses (e.g., Vuzix Blade) can monitor environmental conditions to adjust greenhouse parameters.

c. Health and Safety of Workers

• Product Example: Blackline Safety G7c
  • Functionality: Combines gas detection with environmental monitoring and worker location tracking.
  • Use Case: Field workers are alerted in real-time to toxic gas levels or extreme temperatures through a smartwatch-like wearable.

d. Pest and Disease Prediction

• Product Example: Pessl Instruments iMETOS® eco D3
  • Functionality: Collects data on environmental conditions conducive to pests or diseases and integrates with wearable systems for notifications.
  • Use Case: Alerts farmers to conditions that favor pest infestations, enabling preventive action.

3. Applications in Industrial Settings

a. Workplace Safety Monitoring

• Product Example: Honeywell BW Ultra
  • Functionality: A wearable multi-gas detector that monitors air quality and alerts users of hazardous conditions.
  • Use Case: Factory workers wear this device to detect toxic gas leaks and maintain safe working environments.

b. Disaster and Accident Prevention

• Product Example: Msa Altair 4XR
  • Functionality: A rugged, wearable gas detector that connects to mobile devices for real-time alerts and analytics.
  • Use Case: Alerts workers to dangerous levels of gases like carbon monoxide or hydrogen sulfide, preventing accidents.

c. Location and Environmental Tracking

• Product Example: Spot Gen4 GPS Tracker
  • Functionality: A wearable GPS device with environmental monitoring capabilities, ideal for remote areas.
  • Use Case: Used by miners or construction workers to track location and receive environmental alerts (e.g., weather changes or air quality issues).

Conclusion

Environmental sensors, paired with specific wearable products such as the Garmin Fenix 7, Honeywell BW Ultra, and L’Oréal My Skin Track UV, have practical applications in enhancing safety, productivity, and health in outdoor and industrial settings. As wearable technology continues to evolve, integration with IoT platforms and advanced sensors will further expand their capabilities across diverse sectors.
