Unless I misread, the lens is integrated, but Bosch recommends an optical window to protect the device. The integration guide is pretty comprehensive. Many fan-based air sensors require some specific enclosure considerations to separate the in/outflow. Sparkfun sell a module with a ground plane + thermal pad as heat sink. This is suggested as OK by Bosch, though adding a small heatsink is probably a good idea, or just mount the enclosure on a metal surface. https://www.sparkfun.com/sparkfun-air-quality-pm1-pm2-5-pm10-sensor-bmv080-qwiic.html https://www.sparkfun.com/sparkfun-air-quality-pm1-pm2-5-pm10... https://www.bosch-sensortec.com/media/boschsensortec/downloads/handling_soldering_mounting_instructions/bst-bmv080-hs000.pdf https://www.bosch-sensortec.com/media/boschsensortec/downloa...
