Please Help Vette My Proposed BOM For Upcoming Project

Hello,

I am planning a semester research project to see if I can extend a battery's life before needing charging using ambient signals like RF, indoor lights, thermal etc. These are the presumptive materials I have come up with to do this. The Arduino circuit will basically show temp, humidity, pressure when a button is pressed and if I press another button, I also plan to find a way to keep track of the battery charge (if that's really possible) so I can see the effects of energy harvesting.

This is the list:

· Arduino Pro Mini 3.3V / 8MHz = $4.67 per unit: Link

· 2 push buttons = $0.25 per unit: Link

· BME280 = $12.99 per unit: Link

· Lux meter = $12.98 per unit: Link

· Battery case = $0.63 per unit: Link

· 18650 Li-ion flat top 2000mAh battery = $6.3 per unit: Link

· 2.15 inch waveshare e-paper display = $13.99 per unit. Link

· DFM8001 energy harvesting kit = $16.90 per unit. Link, DigiKey Link

· Two LL200-2.4-75 indoor solar cells = $4.53 per unit. Link

· USB to Serial converter FTDI breakout = $6.49 per unit. Link

I would greatly appreciate more eyes on it for anything I might be overlooking or any advice or suggestions on what I already have. Thank you for your time.
