Setting up a simple environment monitor using hardware is fairly straightforward. In this recipe, we are going to take a proof of concept with some simple hardware attached to it. In the There's more... section, we will talk about how to take a design like this and go to production with it, even if you don't have electrical engineers (EEs) on your team. To do this, we are going to introduce Fritzing, a hardware designer. Although it is not as powerful as KiCad or Altuim Designer, it is a tool that a person who is not an electrical engineer can give to an EE or a manufacturing partner and get circuit boards designed and printed.
The goal of this recipe is not really to show you how to create a temperature and humidity sensor. Temperature and humidity sensors are the Hello World of IoT. Instead, this recipe focuses on implementing these on constrained devices in a rapid way via manufacturing. Not all IoT projects can be done...
