The BH1750 is a digital ambient light sensor module which uses I2C to communicate. The BH1750 provides you with a digital value in lux (Lx) over a range of 1 - 65535 lx. See Digital 16bit Serial Output Type Ambient Light Sensor IC for more information.
| BH1750 | ESP8266 |
|---|---|
| GND | GND |
| VCC | 3.3V |
| SDA | GPIOx |
| SCL | GPIOy |
In the Configuration -> Configure Module page assign:
- GPIOx to
I2C SDA (6) - GPIOy to
I2C SCL (5)
After a reboot the driver will detect BH1750 automatically and display Illuminance.
Sensor sends a tele/%topic%/SENSOR JSON reponse:
{"Time":"2019-11-03T20:45:37","BH1750":{"Illuminance":79}}
