Product overview
The BWSENSING BW-IMU100S is a miniature inertial measurement unit combining gyroscope and accelerometer sensing for integration into unmanned aircraft and other equipment. Applications include low-speed drones, platform stabilization, construction machinery, automated guided vehicles, autonomous driving, robots, unmanned vessels and underwater robots. The gyroscope measures within ±500°/sec, while the accelerometer measures ±10 g along the X, Y and Z axes. Dynamic and orthogonality compensation support the sensing configuration, which provides RS422 output, a baud rate of 115200 and sampling up to 200Hz.
The packaged unit measures 22.4×22.4×10mm and weighs ≤30g. Length and width may vary by ±1mm, with actual dimensions taking precedence when allocating installation space. Electrical requirements are 5V DC and 10mA operating current. Temperature compensation accompanies an operating range of -40~85℃; the storage range is -55~100℃. Shock resistance is ≥2000g and the vibration rating is ≥20grms. Across the full temperature range, gyroscope bias is ≤150 °/h and accelerometer bias is ≤5mg; their respective 1σ bias stability and repeatability limits are ≤12 °/h and ≤0.3mg.
