The Project: Wirelessly Monitor Temperature, Humidity, and Barometric Pressure

For this build, we're going to create a simple point-to-point closed WiFi system that reads the data from an environmental sensor and sends it to a display somewhere else. We'll keep this example as simple as possible by using our hardware, utilizing the Qwiic Connect System to connect our hardware without the need for soldering. The hardware includes a pair of ESP32 Thing Plus Wroom modules, a Qwiic Environmental Combo Breakout, a SparkFun Qwiic Single Relay, and a couple of Qwiic Cables. (And of course, a power supply - either battery or wall charger - for each.) You can add all the items of this tutorial to your cart using the wishlist below.
