META TOPICPARENT	name="AFNOGWorkshop2019"

The WeMos D1 mini and its sensor and actuator shields

Introduction

Line: 69 to 69

The SHT-30 shield with a SHT-30 I2C digital temperature and humidity sensor
The DHT11 shield with a DHT11 digital temperature and humidity sensor. This device uses its own private serial communication protocol

Here is an overview table showing the devices and their connections:

For each of the devices I create 2 directories:

a driver directory containing programs testing the module without Cayenne communication
a cayenne directory for the final program
