Renesas Electronics Corporation has added an IP67-certified waterproof package and a new AI-based algorithm to its popular ZMOD4510 Outdoor Air Quality (OAQ) gas sensor platform, which can enable ultra-low-power selective ozone measurements. ZMOD4510 is a compact and fully calibrated digital OAQ sensor system that can detect particular ozone levels while consuming less than 200uW of electricity. Because of the low power consumption and waterproof package, the sensor can be used on wearables, smartphones and Industrial Monitoring Devices. Moreover, it offers visibility into the air quality in users’ immediate environments without reporting on other pollutants.
The unique software configuration of ZMOD4510 provides design flexibility for smart sensing systems, which allows firmware updates in the field to enable new, application-specific capabilities such as selective ozone detection and because of its ability to quantify selective Ozone levels in concentrations as low as 20 ppb coupled with its low power, small size, and outstanding flexibility, it turns out to be an ideal solution for mobile and wearable devices, along with industrial applications such as wireless security cameras and parking meters.
Its new waterproof packaging in a tiny 3mm x 3mm x 0.9mm LGA package allows the sensor to operate in harsh and submersible environments. The IP67-rated sensor maintains superior accuracy and high performance while eliminating the need for expensive waterproofing systems. The sensor is shipped fully calibrated in the hydrophobic and oleophobic package and customers can apply a conformal coating on their circuitry rather than adding an external membrane to the module.
The selective measurement capability of ZMOD4510, allows devices such as smartwatches, phones, and smoke detectors to monitor for harmful ozone gasses, and optimizing the ZMOD4510 for very low power is key to enabling the longer life cycles required for these types of battery-powered devices. Apart from this, the ZMOD4510 is calibrated to the U.S. Environmental Agency’s (EPA) Air Quality Index for measuring ozone, and is highly resistant to siloxanes, enabling exceptional reliability for use in harsh environments.
Uwe Guenther, Senior Director, Sensing Solutions, IoT and Infrastructure Business Unit at Renesas said that “Measuring outdoor air quality really is about location, location, location, as levels can vary dramatically from street to street and even on opposite sides of the same street. The enhanced ZMOD4510 gives manufacturers the selective high-precision sensing, ultra-small size, and long battery life they need for battery-powered devices like smartwatches and phones that offer customers a convenient and customized view of their immediate air quality environment.”
The enhanced ZMOD4510 platform is available in both a standard and IP67-rated sensor package. For more information, please visit www.renesas.com/zmod4510.
