Hardware Hookup
The hookup of this sensor is much easier with the weather:bit carrier board
than with any other microcontroller. We have done a lot of the leg work for
you!
Find the screw terminals for the soil temperature on the weather:bit. Using
your screwdriver, open the screw terminals a bit and insert the wires as
shown in the photo below with the wires from left to right:
• Red to VCC
• White to SIG
• Black to GND
