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 Light Meter Addon based on modules with a TEMT6000:
|
|
- Measures ambient Light Intensity in Lux (lx), Foot Candela (ftcd) and Watt/m^2 (wattsm2)
|
|
- Required Hardware Module: TEMT6000
|
|
- Dependencies: none
|
|
|
|
Connection Scheme:
|
|
--------------------
|
|
|
|
TEMT6000------> ESP8266
