Renesas — ZMOD4510 Digital Outdoor Air Quality Sensor

The ZMOD4510 from Renesas is the first software-upgradeable, digital outdoor air-quality sensor for high-volume applications.

The sensor can detect ozone (O₃) and nitrogen oxide (NO_x) gases, two common causes of poor outdoor air quality. The ZMOD4510 is highly sensitive: it can measure combined O₃ and NO_x in concentrations as low as 20 parts per billion. The air-quality ratings from the ZMOD4510 are correlated with the US Environmental Protection Agency’s air quality index for measuring O₃ and NO_x.

Small and flexible, the ZMOD4510 is ideal for use in industrial and consumer devices. In heating, ventilation and air-conditioning systems, industrial cameras, home automation and smart air purifiers, the air-quality sensor can perform highly sensitive and reliable measurement of outdoor air quality over a long lifetime.

The ZMOD4510 is also easily integrated into end-product designs thanks to the provision by Renesas of compiled firmware. All ZMOD4510 sensors are also factory-calibrated, which lowers customer production costs. The sensor is calibrated electrically and with gas to ensure consistency from lot to lot, an important advantage for manufacturers with long production runs. ZMOD4510 devices are also highly resistant to siloxanes for high reliability when used in harsh environments.

Part of the Renesas ZMOD™ family of gas sensors, the ZMOD4510 is intended for the measurement of outdoor air quality, while the ZMOD4410 detects indoor pollutants such as volatile organic compounds. When used together, the sensors support a smart systems approach in heating, ventilation and air-conditioning equipment, and help to ensure healthy air quality.
