Table of Contents

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.

Configuration

Wiring

BH1750 ESP8266
GND GND
VCC 3.3V
SDA GPIOx
SCL GPIOy

Tasmota

In the Configuration -> Configure Module page assign:

  1. GPIOx to I2C SDA (6)
  2. GPIOy to I2C SCL (5)

After a reboot the driver will detect BH1750 automatically and display Illuminance.
