What about PM2.5?

Our research suggests that VOC measurements are the single most important measurement for indoor air quality. PM2.5 sensors require a lot of power and are bulky. In order to keep our form factor, we decided not to include a PM2.5 sensor within the DN690R. That said, we are working on a companion device to the DN690R which will wirelessly extend the DN690R to include PM1.0, PM2.5 and PM10.

Will I need an app?

To keep things simple, the Entrepreneurs Clock stands alone, no app required. But, we're also innovating towards a future IoT hub. Your DN690R is equipped with a wireless radio so that we can expand its capabilities in the future.

What about firmware updates?

Yes! The DN690R is designed to evolve, with regular firmware updates that enhance its features and functionality – without complicating its use. Thanks to its wireless update capability, your device will always be the state-of-the-art in air quality monitoring tech.
