Product overview
The BWSENSING BW-IMU100C combines gyroscope and accelerometer measurement functions for integration into unmanned aircraft, robots, autonomous vehicles and stabilized platforms. Its gyroscope measures angular rates up to ±400°/sec with 0.01°/sec resolution, while the accelerometer covers ±3.6g on the X, Y and Z axes with 0.01mg resolution. Sampling reaches up to 500Hz. Dynamic compensation, orthogonal compensation and temperature compensation are features of the unit, with selectable RS232, RS485 or TTL interface output for connection to the host system.
The packaged product measures L60 × W59 × H29mm, while the bare-board product measures L44 × W35 × H11mm. Bare-board length and width may vary by ±1mm, with actual dimensions governing. The unit requires 9-36V DC and draws 30mA, with a 40mA maximum. Its operating temperature range is -40 to 85°C, and its storage range is -55 to 100°C. Accelerometer bias stability is 0.001mg at 25°C, 100s and 1σ, and 0.01mg at 25°C, 10s and 1σ.
