ESP32 sensors for greenhouse

Post by ajocius » Fri Apr 12, 2019 1:30 pm

I have made drawing for intended new PCB that will hold several sensors to monitor temperature at various locations of greenhouse and one switch that will control heater (when temperature drops below set during the night). I would appreciate your comments, suggestions on Additional elements like capacitors, resistors that would improve this layout.

All DS18B20 can be connected to the same pin.

Good point, but I have too many available inputs on ESP32, so thought will be easier to control and code it
