Hardware and software requirements
For this project, you will need the following hardware:
Of course you need an ESP8266 chip. You can, for example, use an Olimex ESP8266 module.
You will also need a temperature sensor. I used a DHT11 sensor, which is very easy to use and will allow us to measure the ambient temperature and humidity.
You will also need a 3.3V FTDI USB module to program the ESP8266 chip. Finally, you will also need some jumper wires and a breadboard.
This is a list of all the components that will be used in this chapter, along with the sources where you can purchase them:
