We've completed the first batch of optimisations and have begun DIYing them at a regular pace. Sharing them is now very quick, just like with all sensors – we can usually dispatch them within one to two days.

After extensive experimentation with the SPS30 and SCD40, we concluded that combining them might prove advantageous.
This collaboration resulted in a device utilising two sensors we've frequently employed recently. Their integration delivers PM2.5 monitoring capabilities alongside CO2 detection – a potentially intriguing combination.

We invite everyone to join this new adventure, hoping it becomes a useful sensor fixture – like all SCREEK sensors, working quietly yet reliably around the clock.

Thank you all, and we hope you enjoy it.

Regarding the firmware and usage process, it employs a carefully customised ESPHome firmware that simplifies the workflow. Simply power the sensor, connect to its hotspot ENV-SENSOR-ENV-CP, and configure your Wi-Fi via the pop-up page (if it doesn't appear, ensure you're connected to the hotspot and navigate to http://192.168.4.1 to access the Wi-Fi setup interface). Once complete, Home Assistant will automatically discover the sensor and add it directly.

The entire configuration process is finished once the sensor obtains its Wi-Fi credentials.

In the design phase, we employed a blue casing for testing purposes. Ultimately, we shall standardise on a white casing for the final DIY sensor form. As ever, we aspire to a design that is both simple and elegant – devoid of superfluous screws, featuring clever snap-fit mechanisms, and boasting precision down to 0.1mm. We shall undertake further optimisation on the final print. Fresh off the press, I must say, it looks rather smart :)
