I have the Si1144-AAGX HRM sensor and I need it to connect to the "arduino uno-nano" development kit, its for my school project.
so is it possible? or i need the HRM-WG-BIO-44 development kit?
The SI1144 is intended for commercial use only. If you're a student doing a project, we recommend using the Biometric Sensor Expansion Card: http://www.silabs.com/products/sensors/Pages/biometric-exp-evb.aspx.
This can be purchased from our website or from some catalog ditributors.
