TFPM02B - Particulate Matter Sensor for ThunderFly TF-ATMON system

Particulate matter sensor for TF-ATMON system is based on Sensirion SPS5x, TFGPS01 and PX4 autopilot firmware with suitable driver. The PX4 driver emits uOrb messages which are translated to MAVLink messages ready to log onboard and transmit to TF-ATMON enabled GCS.

Look to the following video for a demonstration flight of a sensor mounted on TF-G2 autogyro.

The SEN5x sensor is directly connected to the I²C bus on PX4 autopilot supported hardware by using JST-GH cable.

The main features

  • Particulate matter sensing PM1.0, PM2.5, PM4 and PM10 in range 0 - 1000 μg/m³ (Accuracy ±10 %)
  • Humidity sensing 0 - 90 %RH (Accuracy ±4.5 %RH)
  • Temperature measurement -10 to 50 °C (Accuracy 0.45 °C)
  • VOC in 0-500 VOC Index corresponds to range 0 - 1000 ppm ethanol equivalent.

Unfortunatelly the sensor does not output number concentrations, for that values use the TFPM02A variant.
