Smart Air Quality Sensor Module

The Renesas RRH62000 is making waves as the first multi-sensor air quality module to hit the market. This innovative device integrates multiple sensor parameters in a compact design, allowing for the accurate detection of different particle sizes, volatile organic compounds, and gases that are harmful to human health. Equipped with a Renesas microcontroller (MCU), the intelligent sensor module is perfect for a wide range of air monitoring applications, including air purifiers, smoke detectors, HVAC systems, weather stations, and smart home systems. Its robust firmware ensures that customer products can easily comply with various air quality standards worldwide.

One of the standout features of the RRH62000 sensor module is its incredibly small footprint, measuring just 46.6 x 34.8 x 12 mm. Despite its compact size, this module packs a punch with the inclusion of the RA Family MCU from Renesas and seven sensor signals. These sensors include the laser-based PM1/2.5/10 sensor, ZMOD4410 gas sensor, and the HS4003 humidity and temperature sensor. By combining these sensors, the RRH62000 can detect particulate matter, total volatile organic compounds (TVOC), estimated CO2 levels, temperature, and humidity all within a single system. With all key components pre-integrated and fully calibrated at the factory, developers can jumpstart their sensor system designs straight out of the box.

The importance of monitoring air quality has been underscored by the COVID-19 pandemic, leading to a surge in public interest regarding the impact of air pollutants on health. Many are now aware of how pollutants can affect respiratory health and overall well-being. What is less known is that indoor air can be significantly more polluted than outdoor air, with pollutants such as dust, paint fumes, cooking smoke, pollen, and HVAC filter particulates posing serious health risks. These pollutants can enter the respiratory system, causing lung damage, cancer, and other health issues.

To address these pressing concerns, the RRH62000 sensor module is designed to monitor a wide range of air quality conditions. Utilizing laser-based technology for enhanced precision compared to traditional LED methods, this module can monitor concentrations of PM1, PM2.5, and PM10 particulates, as well as absolute or relative TVOC measurements in various power mode settings. This high level of accuracy ensures that the RRH62000 can deliver real-time data on surrounding air quality, with its on-board MCU enabling seamless detection and analysis.

Engineers and developers can leverage the RRH62000's advanced features, including building standard firmware and AI algorithms, to tailor the sensor module to meet the requirements of different green air quality standards in public buildings. By incorporating these features, institutions like schools can easily adapt the sensor module to comply with standards such as The Well Building Standard (WELL), Home Ventilating Institute (HVI), and RESET. This flexibility allows for seamless integration of the RRH62000 across various locations, with the ability to update firmware as needed.

Furthermore, the RRH62000 is part of Renesas' comprehensive lineup of compatible devices, offering a range of Winning Combinations that cater to diverse needs. By combining the RRH62000 with other Renesas products, such as the RA6M3 and RL78/G14 MCUs, and various power devices, innovative solutions like the In-home Air Quality Monitoring System and Air Quality Monitor (PM2.5) with Secure Cloud Connection are made possible. These solutions provide cost-efficient, compact, and modular options for modern appliances, ensuring optimal air quality and energy efficiency.
