OpenMQTTGateway Addon - ESP8266 or Arduino program for home automation
Act as a wifi or ethernet gateway between your 433mhz/infrared IR signal and a MQTT broker
Send and receiving command by MQTT
This is the MQ2 GAS Sensor Addon based on modules with a MQ:
- Measures flammable gas
- Required Hardware Module: MQ2
Connection Scheme:
--------------------
MQ-2 -------> Arduino Uno ----------> ESP8266
==============================================
Vcc ---------> 3.3V or 5V------------> 3.3V or 5V
GND ---------> GND ------------------> GND
A0 ----------> Pin A0 ---------------> A0
D0 ----------> Pin D4 ---------------> D4
