+  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
