Hi,
I was playing around with capacitive liquid level sensors and was trying to understand the difference between the MPR121 and fdc1004. Obviously, the fdc1004 is a lot more pricey than the mpr121.
With proper shielding i am confused to what level of improvement the fdc1004 has over mpr121.
My experiment for MPR121 was to have 7 copper tapes around the plastic jar at different levels connected to 7 inputs of MPR121. They were able to give me readings and results were consistent. I havent played around with the fdc 1004 but the breakout board is 20.99, a bit too much for a beginner hobbyist like myself. However, if its worth the buy, i will give it a shot. Just wanted to understand what the community thinks.
Anyone with that info. Thanks
