Bioaerosol sensor

Particle size detection range: Many sensors detect particles in the roughly 0.5 µm to ~30 µm range — that covers many bio‑aerosols like spores, pollen, bacterial clusters.

Detection method: For example sensors use fluorescence / laser induced fluorescence to distinguish biological from non‑biological particles.

Response time & sensitivity: Real‑time or near‑real‑time monitoring is important for timely action, with alarm capabilities when levels exceed thresholds.

Data output & connectivity: Ability to integrate into monitoring networks (Ethernet, RS‑232/485, wireless) so you can log alerts, send remote notifications, etc.

Operating environment / durability: Consider temperature/humidity range, whether the system supports continuous unattended operation, maintenance/consumables.

Application & calibration: Match the sensor to your environment (lab/clean‑room vs general indoor vs public space) and check calibration & validity of biological detection (false positives, distinguishing inert vs live). Research articles highlight that not all “fluorescent particles” are biological.
