esp8266 / NodeMCU MQTT and PIR Motion Sensor Example with WiFiManager

This is an example sketch for the esp8266 with a PIR motion sensor that sends an MQTT message when motion occurs to the configured MQTT broker.

It also uses the tzapu WiFiManager package to allow the user to setup wifi.

It is a fork of my basic esp8266 MQTT example sketch.

Hardware

For this project I'm using a NodeMCU esp8266 board. The HiLetgo board. There's a good pinout diagram for the ESP8266 here

I'm using the HC-SR501
