ERICCO INERTIAL TECHNOLOGY ER-MIMU-104 Low-cost Attitude Control MEMS IMU Introduction ER-MIMU-104 is a micromechanical technology (MEMS)-based inertial measurement unit (IMU). Built-in three-axis gyroscope and three-axis accelerometer to measure three-axis angular velocity and acceleration. The ER-MIMU-104 uses a high-quality, reliable MEMS accelerometer and gyroscope. It can be used for attitude measurements. The product uses high-performance MEMS inertial devices, which have high reliability and high robustness, and can accurately measure the angular velocity and acceleration information of moving carriers in harsh environments. Features Three-axis digital gyroscope: Dynamic measurement range:±400º/s; Bias instability: 1º/h (Allan variance); Angle random walk: 0.2º/√h. Three-axis digital accelerometer: Dynamic measurement range: 30g; Bias instability: 10ug(Allan variance); Ensure accuracy over the full temperature range (-40°C~80°C): Built-in high-performance temperature calibration and compensation algorithm; Low power consumption: 2W Communication interface: 1 SPI Application Industrial instrumentation attitude measurement Robot attitude control Indoor people tracking, navigation, and tracking Platform stability and control Pipeline Inspection, exploration & positioning Whatsapp/Wechat/Mob:8613992884879 Websit : www.ericcointernational.com E-mail : ericco001@ericcointernationa

Product composition and working principle The product is mainly composed of three-axis MEMS accelerometer and gyroscope. The working principle is as follows: the gyroscope and accelerometer data are collected by ARM microcontroller, three high-precision gyroscopes are collected by 1-channel digital interface SPI, and three accelerometers are collected by another 1-channel digital interface SPI. All sensors are calibrated and compensated in software after acquisition. Product technical characteristics a)The product is designed for miniaturization and low power consumption; b)Products with wide...

Note: For gyroscope, accelerometer fraction high 16bit, and low 16bit, the final result of addition is calculated separately Test interface operation description The user installs the test interface on the computer, open xInsConnect.exe,as shown below. Click "COMCFG" to configure the baud rate, which is the COM port required; Click the "Open" button power on the IMU. Precautions for use 1)Installation error description Internal orthogonal compensation has been carried out for the whole product. If the platform used by the product cannot guarantee the accuracy of the benchmark after installation,...
