Specification

WitMotion Bluetooth 2.0 BWT61CL 6 Axis Sensor AHRS IMU MPU6050 Digital Tilt Angle   Accelerometer   Gyroscope on PC/Android/MCU

Technical Specifications:

BWT61CL’s scientific name is the AHRS IMU sensor. A sensor measures 3-axis angle, angular velocity, acceleration. Its strength lies in the algorithm which can calculate the three-axis angle accurately. The robust housing and the small outline makes it perfectly suitable for industrial retrofit application such as motion capturing, engineering machine monitoring, etc.

Persued for best data accuracy and stability: WTMOTION patented zero-bias automatic detection calibration algorithm and R&D dynamic fusion algorithm outperforms traditional accelerometer sensor.

    When combined with the "Remote Level" Android app, I have found the WitMotion BWT61CL Bluetooth MPU6050 Gyro+Accelerometer a very useful & cost-effective way to level our T@B camper. It's unfortunate that it is currently not available - maybe a result of China tarriffs & will be back hopefully? I wish the bluetooth connection was a bit more reliable at greater distances such as from the driver's seat of tow vehicle (which sometimes loses connection), but otherwise very helpful for adjusting tongue jack & left/right leveling. After trial & error, I found that choosing the app orientation setting "Left Edge", with the device oriented with label facing upwards & label bottom forward, this produces the expected results with above app after saving settings with the device mounted on leveled trailer. See photos showing device mounted under a cabinet, where front of trailer is at right/through window. This orientation uses the X-axis for left/right leveling and Y-axis for front/back. I used a simple USB adapter plugged into a 120V AC outlet.
    Much cheaper than another popular device of this type costing around $130. I have no incentive for giving this review other than being a satisfied cusutomer.

    For $25 this is a nice device, it has a very decent battery life and the BT connection seems very reliable once it is done. I am not sure why but some times it takes several attempts to connect to my tablet. One of the reasons I decided to get this device was because of the App offering, so I was really disappointed when I saw some of the app menus in Chinese.

    I use this device with my own Android app. It works exactly as described, and meets all my expectations and requirements. I programmed my app to connect to the BWT601CL's Bluetooth interface exactly as described by the Google Android Bluetooth development guide, with the additional information provided by the WitMotion documentation for the detailed data format protocol. Like most programming efforts, this was not totally headache-free but the issues were due to my own Bluetooth inexperience and bugs, not due to WitMotion.

    The device can also be accessed and tested with the "Mini IMU" app provided by download from WitMotion, which shows angles, angular velocity, and acceleration and also allows for admin and calibration. I did not try to use a hardwired PC interface as all functionality is provided over wireless Bluetooth. The documentation states that admin functions are not available over the PC serial interface. This makes sense to me, since it's a wireless Bluetooth device, and there are other different available devices intended for hardwired applications, and even a USB-bluetooth interface for PCs.

    This product can be very confusing to set up as their online template did not work for me. However, their customer service team is AWESOME and genuinely cares about their customers. We were able to eventually get my accelerometer up and running. It is fantastic and has a great sampling rate. Highly recommended!
