Theengs OpenMQTTGateway - We Unite Sensors in One Open-Source Interface
|
|
|
|
Act as a gateway between your 433mhz, infrared IR, BLE, LoRa signal and one interface like an 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 -------> ESP8266
|
|
==============================================
|
|
Vcc ---------> 3.3V or 5V
|
|
GND ---------> GND
|
|
A0 ----------> A0
|
|
D0 ----------> D4
