Polverine is a mikroBUS-compatible board featuring the BMV080 PM2.5 sensor and the BME688 gas sensor, both from Bosch Sensortec. These sensors are managed by an on-board Espressif ESP32-S3-MINI-1 dual-core microcontroller with 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE). Polverine can be programmed with Arduino, Eclipse, and PlatformIO/VisualStudio IDEs. Demo firmware makes sensor evaluation quick and easy.

Compact & Fanless

The new BMV080 sensor is the world’s smallest PM2.5 air quality sensor. Its innovative fanless design keeps it extremely compact and relatively low-power, with a sleep current draw of less than 30 μA. Polverine allows you to quickly put the BMV080 to use.
