Hi all! can anyone tell me, soil moisture sensor on esp 8266 node mcu, only one can be connected??? if not, you can give a hint where to dig. (I’m new to this business) I managed to connect one, it works properly, I’m happy. for example, I connected 5 temperature sensors to d6, but they each have their own address.
Each sensor requires an analogue input. The ESP8266 only has one of these. Get an ESP32. They have 18 analogue inputs and don’t cost much more than the ESP8266. It’s a lot less mucking around than trying to do analogue multiplexing.
oooh, and that I’m so not careful. Thank you very much, I will certainly order, and I will do it !!! rescued again.
