Bicycle Power Meter

May 31 2023

This bicycle power meter video shows how to measure the power output by a person riding an exercise bike. The solution is a low power, wireless system comprising a MAX41400 instrumentation amplifier connected to strain gauges mounted to the bicycle’s crank arm. A MAX11108 ADC and a MCU communicate wirelessly with a tablet. The solution has a low-cost bill of materials and low power consumption for long battery life. The rider can also use a wrist-worn, ADI biometric sensor platform to stream data such as heart rate, oxygen saturation, and ECG to a PC GUI.
