BH1750 ambient light sensor~
This feature is included only in tasmota-sensors.bin
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 datasheet for more information.
Configuration~
Wiring~
BH1750 | ESP8266 |
---|---|
GND | GND |
VCC | 3.3V |
SDA | GPIOx |
SCL | GPIOy |
Tasmota Settings~
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.
