How do I connect a DHT22 SKU (018-DHT22) and Soli Moisture SKU (SEN0114) on a breadboard?
On an Arduino Uno R3 Borad.
Hi Mendel, Welcome to the forum
The first thing you will need to check is the pinout of all three devices. The pinout for your Arduino can be found here: The Full Arduino Uno Pinout Guide [including diagram]
The soil moisture sensor has an analog output signal and can run on 3.3V or 5V, so it’s easiest to connect its 3 wires to the 5V pin for power, The Analog to Digital Converter 0 input (ADC0) for signal, and the ground reference connected to the ground pin. I’ve highlighted these three connections in the diagram below.
Your soil moisture sensor cable has a female header socket output (the same as the Arduino sockets) so I’d recommend connecting it with prototyping wire like these: Jumper Wires - Connected 6" (M/M, 20 pack) Australia
Just following up for the other DHT22 sensor, we have a tutorial on connecting one to an Arduino available here:
Thank you for your assistance.
