It uses a fanless laser-based optical technology that detects particles traveling in free space via ambient airflow, eliminating the need for fans, air inlets, or channels. The sensor emits laser light focused approximately 5 mm above its lens surface; particles crossing the focal region back-scatter light that is detected by integrated photo-detectors, with Doppler shift used to determine airflow velocity.\n\nThe BMV080's revolutionary small form factor (4.4 mm x 3.0 mm x 20.0 mm, 0.092 g) and low power consumption enable integration into ultra-compact IoT devices. Its novel measurement principle — immune to ambient light and requiring no moving parts — makes it completely maintenance-free and allows dust-proof or waterproof integration designs. The sensor consists of an LGA package, lens, and flex-PCB, connected to a host MCU via SPI or I2C, where the Bosch-provided sensor driver processes raw data into calibrated PM concentration values.\n\nThe BMV080 supports continuous and duty-cycling measurement modes with three selectable algorithms (High Precision, Balanced, Fast Response), delivering output data at up to 0.97 Hz. It is classified as a Class 1 laser product (IEC 60825-1) and is designed for a 10-year operating lifetime (MTTF) under standard indoor conditions.\n\n## Key Specifications\n\n| Parameter | Value |\n|---|---|\n| PM2.5 Measurement Range | 0 -- 1000 ug/m3 |\n| PM2.5 Output Resolution | 1 ug/m3 |\n| Minimum Detectable Particle Size | 0.5 um |\n| Relative Particle Velocity | 0.02 -- 1.5 m/s |\n| Precision | +/-10 ug/m3 (0--100 ug/m3); +/-10% (101--1000 ug/m3) |\n| Linearity (Pearson R) | >= 0.98 (0--400 ug/m3); >= 0.95 (401--1000 ug/m3) |\n| Maximum Output Data Rate | 0.97 Hz |\n| Interface | SPI, I2C |\n| Average Total Current (continuous) | < 68 mA @ 0.97 Hz ODR |\n| Sleep Current | < 30 uA |\n| Start-up Time | 1.9 s (polling) / 2.9 s (IRQ) |\n| Operating Lifetime (MTTF) | 10 years |\n| Sensor Dimensions | 4.4 mm x 3.0 mm x 20.0 mm |\n| Sensor Weight | 0.092 g |\n| Laser Class | Class 1 (IEC 60825-1) |\n| Operating Temperature | +15 C to +65 C |\n| Operating Humidity | 0 -- 95 %rH (non-condensing) |\n\n## Features\n\n- Ultra-compact form factor (4.4 x 3.0 x 20.0 mm, 0.092 g)\n- Precise PM1, PM2.5, and PM10 mass and number concentration measurement\n- Innovative fanless laser-based optical design\n- Noiseless device operation with no moving parts\n- No inlets or channels needed -- minimum industrial design impact\n- Maintenance-free operation\n- Novel free-space measurement principle using ambient airflow\n- Enables dust-proof or waterproof integration\n- Three measurement algorithms: High Precision, Balanced, Fast Response\n- Continuous and duty-cycling measurement modes\n- Class 1 laser product (eye-safe)\n- 10-year operating lifetime (MTTF)\n- Obstruction detection with software flagging\n- RoHS compliant\n\n## Pin Configuration\n\n| Pin No. | Name | Type | Description |\n|---|---|---|---|\n| 1 | VDDL | Power | Laser supply voltage (3.3 V).
