I am thinking out how to build a wifi connected temperature control for my meat smoker. I need 2-4 temperature probes. At minimum, one for the grill inside temperature and one for the meat I'm smoking. More to get more precision or do multiple pieces of meat at once. The probes are analog sensors.
Using the nodeMCU is a problem in that there is only one analog pin. But the nodeMCU is perfect as far as wifi and HS3. I ran across this technique of multiplexing analog sensors. I use the API sketch so I should be able to implement this easily enough. If it works, now I'll effectively have multiple analog devices.
Just thought I would pass it along.
