I am hoping you can help?
I have a spinning bike and I would like to measure power data using a wheatstone bridge connected to the brake, plus a bluetooth heart rate sensor. Then I should log the data and produce a graph of power versus heart rate. I have looked on the shop and I think these items might help me:
Product Code : RB-Onl-38 - to connect the bridge;
Product Code : RB-Suf-03 - to communicate data to PC for logging
Could you let me know what else might be required?
Thanks,

Hi,
Welcome to the RobotShop Community.
You can use the Load Cell / Wheatstone Amplifier Shield (2ch) to read load cell measurements. The Load Cell Shield would be used with an Arduino Microcontroller Board. It can be stacked on top of an Arduino UNO Board. A HX711 module like the Gravity HX711 Load Cell / Wheatstone Bridge Interface or the HX711 Load Cell Amplifier can also be used to read load cell measurements.
You would also need a heart rate monitor module, we offer this Gravity Heart Rate Monitor Sensor for Arduino, this AD8232 Heart Rate Monitor or this BL18 ECG Maven Heart Rate Monitor Module.
For data logging, you can use a Bluetooth module to send data to PC wirelessly (as you already planned) or you can also log data into an SD Card using a Data Logging Shield like the Data Logging Shield for Arduino
