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 Climate Addon:
|
|
- Measures Temperature, Humidity
|
|
- Generates Values for: Temperature in degrees C and F, Humidity in %
|
|
- Required Hardware Module: AHTX0 (AHT10 & AHT20)
|
|
- Required Library: Adafruit AHTX0 by Adafruit
|
|
|
|
Connection Schemata:
|
|
--------------------
|
|
|
|
AHT10 ------> ESP8266
|
|
==============================================
|
|
Vcc ---------> 3v3 (3V)
|
|
GND ---------> GND
|
