The Globalsat CO sensor is an IoT-ready environmental sensor that measures carbon monoxide (CO) concentration along with ambient temperature and humidity. Typical measurement range is up to ~500 ppm CO, making it suitable for monitoring air quality in areas like parking garages, basements, kitchens, and industrial spaces where CO buildup can occur.
The Globalsat CO₂ sensor measures carbon dioxide (CO₂) levels along with temperature and humidity. With a typical measurement range up to ~10,000 ppm CO₂, it’s well-suited for monitoring indoor air quality in schools, offices, greenhouses, and other occupied or controlled spaces.
