If you need any help in choosing a yellowcog product or advice on how to build your next project then just email us.
Measuring weight (or force) accurately requires the use of a load cell and sensitive analogue front end to interface to yellowcog's standard hardware. We have worked with a partner company to develop just such a product and it is now available off-the-shelf. The device is coin-sized and interfaces with very high quality load-cells. It is in use on yachts and in other industries to measure both transient and fixed loads. The data is available to standard apps (iPhone and Android) over Bluetooth Low Energy (also known as BLE and Bluetooth 4).
