Environmental Parameters and Air Quality Awareness

Environmental parameters like humidity directly impact perceived comfort among people. At very high or very low humidity levels, we immediately feel uncomfortable. Extended low humidity levels are good transmitting grounds for viruses and high humidity levels breed mold and bacteria.

Since the Covid-19 pandemic, there has been an increase in awareness among people and institutions about air quality. Chemical pollutants like Volatile organic compounds (VOCs), Ozone (O3), and Nitrogen Dioxide (NO2) contribute to serious respiratory illnesses, Asthma and COPD (Chronic Obstructive Pulmonary Disease) when exposed to extended periods of time. At low concentrations of these exposures, we can experience headaches, skin irritation and reduced cognitive abilities directly impacting productivity of employees and students. Monitoring these pollutants continuously indoors is now a priority, with standards such as ASHRAE, WELL, and RESET necessitating the implementation of ventilation or air purification systems based on sensor feedback.

Particulate matter (PM2.5) is the fine dust particles that have a diameter of less than 2.5 micron which is 100 times less than the diameter of human hair. These particles could get into respiratory channels and blood stream and cause serious health repercussions like COPD, respiratory disorders, heart attacks, decreased lung function etc. Particulates need to be monitored and remedied to reduce these risks.

Advancements in Humidity and Temperature Sensor Technology

Humidity and temperature sensor technology has advanced significantly over the past two decades. These sensors have become notably smaller, feature low power consumption (as low as 300nA for a single measurement), and are more cost-effective. We utilize a unique capacitive layer recipe for humidity measurement, enhancing resistance to contamination issues during assembly.

Metal oxide (MOX) sensors have also undergone remarkable evolution in the last 20 years, transitioning from analog sensors in larger TO-can packages to current digital sensors. These modern sensors are compact, exhibit rapid response times, and consume minimal power, enabling battery operation. For example, Renesas offers low-power analog and digital MOX sensors capable of measuring total Volatile Organic Compounds (VOCs), equivalent Carbon Dioxide (derived from VOC levels), Ozone, and Nitrogen Dioxide (NO2). These MOX sensors offer selectable firmware/operating mode options and feature built-in advanced calibration using techniques based on neural networks and artificial intelligence.

Today, many MOX sensors incorporate a digital processor to handle environmental parameters collected from analog sensors, including PM1, PM2.5 and PM10. The on-board MCU needs to manage the onboard sensors and unlock additional features such as event classification, providing users with valuable insights about their environment. Through multi-sensor data and real-time analytics, events like cleaning, cooking, vaping, and smoking can be identified. These integrated sensor modules streamline design processes by offering a compact, pre-calibrated module with built-in firmware, accelerating development timelines.
