Capture sensor data remotely on an SD card - IoT with Arduino #6 | Hardware + code explained!

Did you know you can upload your code to an Arduino, power it up with a portable power bank/AAA batteries and deploy it in a remote setting for days at a stretch, say like a corn field to measure soil moisture over a span of an entire week, without the need to keep the Arduino connected to your computer!!!

But then where would the data be logged or stored if not the Serial Monitor, you may wonder! Well the answer is easy - Use an SD card module to store the captured data and retrieve it once collection is complete.
