Analog multiplexer or analog to digital converter to add analog inputs to NodeMCU? Answered
I asked a question earlier today and yesterday on this forum as well as others about the best analog multiplexer to use to add a few additional analog inputs to a NodeMCU. Someone recommended using an ADS1115 analog to digital converter. I am using this for an automatic garden watering project, where I need to read the values from multiple capacitive soil moisture sensors. Here is a link to the sensors- https://www.aliexpress.com/item/33042209039.html?spm=a2g0o.cart.0.0.52713c006kRBs8&mp=1 My question is, would an analog multiplexer or analog to digital converter be better for this project? Thanks!
