Firmware-Configurable Sensors Can Also Meet EPA and UBA Standards

April 4, 2023

TOKYO, Japan ― Renesas Electronics Corporation (TSE: 6723), a premier supplier of advanced semiconductor solutions, today announced new firmware for its industry-leading ZMOD digital air quality sensors. The latest firmware lets engineers configure the sensors to support various green air quality standards for Commercial & Public Buildings, making them the first sensors in the industry to conform to the requirements of multiple global air quality standards. As commercial HVAC systems move towards autonomous monitoring of our air quality, these systems can now monitor and detect harmful gasses in indoor spaces. Support for environmental standards increases the value of end products and reduces the effort needed to qualify manufacturers for government incentives.

Renesas offers support for the Commercial & Public Building standards, as well as other environmental standards, through its ZMOD digital gas sensors. Both the ZMOD4410 indoor air quality sensor and the ZMOD4510 outdoor air quality sensor offer compliance with the standards. The ZMOD sensors offer customers the ability to configure the sensors through firmware with cloud-based connections. This enables both new and existing ZMOD customers to implement support for the building standards around the globe. A wide range of products can take advantage of this support, including HVAC systems, thermostats, smart appliances and smoke detectors.

“We are excited to see Renesas designing and producing sensors that align with green and healthy building standards,” said Stanton Wong, President, RESET International Standard, an organization promoting data collection and continuous monitoring for buildings via standardization. “As awareness of the health impact of environmental factors continues to grow, monitoring the performance of a building via sensors is the best way to understand and optimize for health in indoor spaces. We look forward to the technological innovations Renesas will bring to the industry.”

“Environmental sensors are a vital tool for ensuring the health and safety of occupants in public and commercial buildings,” said DK Singh, Sr. Director of the Sensor Solutions Business at Renesas. “By using our AI-enabled hardware and firmware platform, customers can easily implement advanced sensors that comply with various building air quality standards to provide a safer and healthier environment for people around the world.”
