Automate your smart home devices with occupancy detection using a PIR sensor, an ESP8266 board, and a Raspberry Pi.
In this tutorial, we’ll show you how to send data from cheap WiFi nodes to a Raspberry Pi over an internal WiFi network.
The boom in technology for the Internet of Things combined with the low cost of the ESP8266 Wi-Fi module has seen an increase in breakout boards by a number of manufacturers. Specifically, we are going to be looking at Adafruit’s Huzzah, SparkFun’s Thing Dev, and the NodeMCU.
