Product overview
The BWSENSING IMU200 is a low-cost inertial measurement unit for applications including unmanned aircraft, robots and platform stabilization. Its inertial sensing specifications cover gyroscope and accelerometer performance. The physical envelope measures L60 × W59 × H29 mm, while the mainboard measures L44 × W35 × H11 mm, providing separate dimensions for planning installation space. Electrical integration uses a 9–36 V DC supply, with selectable RS232, RS485 or TTL output interfaces and a sampling frequency of up to 500 Hz.
The IMU200 incorporates dynamic compensation, orthogonality compensation and temperature compensation across −40°C to +85°C; its operating temperature range is also −40°C to +85°C. Gyroscope bias stability at room temperature is below 2 °/h over 100 seconds and below 20 °/h over 10 seconds, both at 1σ. Accelerometer resolution is 0.01 mg and bias is 0.15 mg. At 25°C, accelerometer bias stability is 0.001 mg over 100 seconds or 0.01 mg over 10 seconds, both at 1σ.
