Airlytix ES1 environment monitor is an ESP32-based environment tracking device that runs ESPHome. The device tracks various environmental parameters like temperature, humidity, air quality (PM1.0, PM2.5, PM4, PM10, VOCs, NOx, CO2), barometric pressure, ambient light, and noise levels. To make things even more interesting, the device ships with a compact 3D printed case and can be integrated with Home Assistant for smart home automation.
Previously we have written about similar environment monitor devices like the Sonoff SC WiFi, V-Air Monitro, and devices like Arduino MKR IoT Carrier Rev2, Radair mini gateway, and Nicla Sense ME designed for environment monitor applications.

As you can see from the specification there is not much hardware-related information available at the time of writing but, the only thing that I could find is that the specification for the ambient light sensor that after looking at the code for a bit which you can find in the Airlytix GitHub repository, along with the STEP and STL files for the case.
The device also includes an unspecified sound sensor (probably a microphone) and an unspecified barometric pressure sensor which can be used to measure sudden changes in air pressure, an early indication of an upcoming storm.
The Airlytix ES1 Environment Monitor is available on Tindie, starting at $134.95 for the kit. A 3D-printed case can be added for $10.80, or get the fully assembled version for $156.54. For further details, visit the Airlytix website.

Wow! This thing is packed and the best it runs esphome (cloudfree & customizable)!
Congrats, this project took many months of work for sure!
Judging from the ESPHome YAML, this has a SEN55 for PM/VOC, a SCD4x for (true) CO2, an SHT4x for temperature/humidity, a DPS310 for barometric pressure, and the VEML6040 as the RGBW color (ambient?) sensor. Sound levels are through an I2S microphone. The YAML is really very well made, using all kinds of advanced ESPHome features and customizations, etc. The GitHub repo even includes even a couple custom out-of-tree components, one for the VEML6040 and one for the sound level meter.
On the downsides: temperature sensors in an enclosed box, close to an ESP is never a good idea. The YAML shows that they’re aware of it, having hardcoded temperature offsets that go up to -6.5 C(!) in their config. It’s not going to be very accurate nevertheless.
The BOM cost for a low quantity run is probably in the $70-80 range and with all the engineering that has gone into it, it’s not an unreasonable price (but not cheap either). For $156, I would have liked to see a proper molded case, though.
