LPMS-B2
The LPMS-B2 is a 9-axis Bluetooth IMU / AHRS. It achieves drift-free orientation through a 3-axis gyroscope, 3-axis accelerometer, and 3-axis magnetometer, with additional temperature and barometric pressure sensors for altitude determination. An embedded 32-bit DSP performs all sensor fusion on-board in real time.
Key Features
- 9-axis sensor fusion (gyroscope, accelerometer, magnetometer)
- Dual connectivity: Bluetooth Classic 2.1 + EDR and BLE 4.1
- Simultaneous operation of up to 7 units on Windows / Android
- Real-time on-board processing via embedded 32-bit DSP
- Barometric pressure and temperature sensing
- Standard and compact OEM form factors
Variants
- LPMS-B2 - Standard 39 × 39 × 8 mm consumer enclosure, 12 g
- LPMS-B2 OEM - Compact 16 × 31 × 4 mm industrial module, 2 g
Both share identical 9-axis sensors, Bluetooth 2.1 + BLE 4.1 connectivity, and on-board 32-bit DSP sensor fusion.
