There is a growing cultural awareness of the significant health impacts of poor air quality, especially in the wake of the COVID-19 pandemic and natural disasters like the wildfires in California. Indoor air quality is an often overlooked aspect of workplace health and safety. Yet it has been shown to have a significant impact on employee productivity and wellbeing. By implementing an IoT air quality monitoring system, businesses can proactively measure and track air quality parameters such as CO2 and particulate matter levels. They can identify and address potential issues before they become problematic. There are also significant business benefits that can be realized through the implementation of demand-based ventilation systems. According to the Department of Energy, HVAC systems use about 35% of a building’s energy on average. Businesses can optimize ventilation rates based on real-time occupancy levels and air quality parameters using indoor air quality monitors. This demand-based approach to ventilation can lead to significant energy savings and reduce HVAC maintenance costs. Golioth makes it easy to develop and deploy a cloud-managed fleet of air quality monitors that can provide valuable insights into the air quality in your workspace. The IoT Air Quality Monitor Golioth’s latest IoT reference design provides an end-to-end example of how to quickly build an indoor air quality monitor proof-of-concept. The reference design measures temperature, humidity, relative pressure, as well as CO2 and particulate matter concentrations. These sensor measurements are periodically streamed to the Golioth cloud via a low-power LTE cellular connection. Using the Golioth REST API, the air quality data enables real-time control and visualization. Let’s take a look at the hardware and software components of this reference design.
