The four load cells allow the 50 kg sensors to read a person’s weight, up to 200 kg, anyway. The load cells themselves are in a bridge configuration which adds the weight on each cell together.

A load cell interfaced to an HX711 Load Cell Amplifier allows an Arduino Nano to measure the mass of the CPAP machine plus the integrated water reservoir.

Most load cells on the market use a cantilever outfitted with strain gages to measure loads.

A motion detector that can record the weakest of vibration caused by a cell in a living organism could be the latest instrument in the search for extraterrestrial life. The motion sensor developed ...
