(Fun fact: You can log data to the SD card with power connected.) - USB-C port is physically lose on my unit. - Included 32GB SanDisk SD card and a USB SD reader. (I'd recommend discarding the latter, mine broke on first use.) - Important note: When connected over USB, it will remain in sleep mode (and not stream data to host device) unless switched on. Documentation and Materials - Full documentation set with FAQ, datasheet, manual and protocol guide (latter required to decode data stream) are difficult to find, hidden away on a Google Drive link. However, some of these (the datasheet and manual) are shared on the desertcart product page and sent from the seller after purchase. - Their GitHub repository appears out of date (at least for this product). Onboard Data Logging - Data files are stored in a hexadecimal stream you'll either write code to translate or use their Windows software to playback/convert. - Time must be calibrated in the app. Based on my limited testing, it drifts approximately 30 seconds/day. - For data logging purposes, some settings (like sensors) are managed via the Windows app. However, others are controlled via a settings file in the SD root (such as scale and logging rate). Windows App - Windows app is unsigned! It worked well within a VMware Windows 11 virtual machine. However, lack of signing prevents any real-world deployment for me. Software available on Google Drive. - Apparently there is a new 2023 version, although hosted on a different Google Drive link I cannot (re)locate. - The Windows app is required to translate the native hexadecimal stream to a useful tab-delimited format. (Unless you write code to perform the same, of course.) Android App - APK on the Google Play Store is outdated (version 3). You can download version 4 from their Google Drive link. - Using multiple devices and versions, I've can update device configuration but never stream/record data successfully. At most, it’ll only capture the initial measurement sample and never stream updates. - I didn't see time calibration or file conversion on Android, just Windows. Recommendations for Witmotion Team - Host latest versions of software, manuals, datasheets on their website. Centralize common software and protocol documents into a single location so they remain current across products. - Please continually deploy latest Android apps to Google Play and sign your software. - Stand-alone data loggers should export information in human-readable format (such as CSV or tab-delimited). At least make it an option with perhaps a reduced log rate.

There is no instructions on how to make this work** A: Hello The link includes the instruction manual and software of the equipment. You can have a look https://drive.google.com/drive/folders/1PXg3k2IAE3R3eKBBWnJRPv0yx0AdOm2N?usp=share_link **Q: Witmotion wt901sdcl i am unable to usb conect up to your software ...... the raw data shows up but that is all** A: Hello Sean, Thanks for your purchase and for letting me know your concern. 1. If raw data shows up, the sensor is actually sending the data. -- Do you have a Skype for video call? My Skype: skype: live:kyle_8394 Or could you please take a short video to show the sensors connecting with your PC including the steps like connection, A video would be hugely helpful for remote diagnosis so I can forward the video to my engineering team for further checking. And get back to you with a feasible solution.
