Measure Light Lux or Intensity with BH1750L Light Sensor Module

[@yashwinb9810]

Hello, how can I fade a led based on the value of lux, I'm not able to include the led output statement inside the if conditional statement.

[@2007xoxox]

Very informative. Thanks for all the effort you put into making these videos.

[@robojax]

You are welcome.

[@pranayreddy6533]

it was very helpful, but I am getting my sensor BH1750 is not recognized while serial monitoring, and says ([BH1750] ERROR: received NACK on transmit of address BH1750 Test begins [BH1750] Device is not configured! Light: -2.00 lx ). have any solution?

[@robojax]

Ply use I2C scanner from robojax.com and see if you are getting the address. If not check wiring or module is bad

thank you Robojax, nice video, good to be used instead of ldr or photoresistor

[@robojax]

You are welcome. Yes this is very precises but 500 times expensive.

[@olivieroreggia]

Very good work ! Is it possible to change the lux value of BH1750 sensor in W/m2 ? Thank you

[@2sadki]

Great demonstration, thank you so much Robojax. You said we can make a solar tracker with this sensors. Can you tell me how?

Very good

Which i2c address is used to increase the range of BH1750 from 65535 lx to 100000 lx.?

Hi Robojax, i m using wemos mini pro, how to change the scl and sda pin connection, i understand fix pin for this in the library is D1 and D2, but i want to use D3 and D4 so where is the changes i should make? Pls help. Thank you.

[@robojax]

you can do wire.begin(SDA, SCL); see it here github.com/esp8266/Arduino/blob/master/libraries/Wire/Wire.h

Hi Ahmed! Informative video, nice but i have faceing one issue when connect DS3231, LCD wit I2C module and BH1750 module but my arduino Uno hang @1300 and 1400 in day time. When isolated BH1750 it work fine.

[@robojax]

salaam alaikum, use I2C scanner to check if you are getting 3, I2C addresses. Click File->Examples->Wire->I2C Scanner and upload the code and see what you are read in Serial Monitor. you should get 3 addresses. then Disconnect them one by one to see which is NOT active and check the wiring. Or connect them ONE by one and check I2C scanner. you will find where the issue is. I am not sure if there is conflict in I2C address. But if there is it is very easy to change the I2C address for the LCD. I have explained I2C address for LCD here kzbin.info/www/bejne/mKKwfnyYor59iZI

[@muhammadadnanahmed8324]

@@robojax ad per your instructions, i connected to upload I2C scanner in arduino uno but, unfortunately my controller was not communicating to upload via serial port so i replaced my controller with other new one and upload after that found address sequentially as Scanning... I2C device found at address 0x23 I2C device found at address 0x27 I2C device found at address 0x57. I2C device found at address 0x68 done

Assalamualaikum Ahmed! I connected BH1750 module with 4 core shield cable of 35ft length.

[@SenyumNetwork]

how about esp32 with bh1750? which pin?

[@robojax]

The same. connect to to SDA and SCL. watch my video on LCD which uses LDA and SLC pins.

[@Ordinary._.Original]

bm6000 bs bh1650 wich one is the best?

[@robojax]

it depends on many factors. Simple open for datasheet for each sensor and compare.

[@gymmusicservice6703]

I want to connect 2 bh1750 with 1 arduino. What is code??

hello i am using a max4009 light sensor can you do a video on it on how to change the i2c adresse from 0x4A to 0x4B , i wanted to use 2 of them at the same time but i don't know how the change the i2c adresse . thanks

[@robojax]

my google search resulted with no datasheet for MX4009.

[@moufidelaroussi414]

Sorry it was max44009 or GY-49

[@robojax]

a simple search showed this library and here is example on how to use 2 sensors github.com/RobTillaart/Max44009/blob/master/examples/max44009_two_sensors/max44009_two_sensors.ino

PLEAS A VIDEO ATTINY DIGISPARK WITH VL53L0X

[@robojax]

it is the same for Arduino and digispark. Just connect SDA and SCL shown here kzbin.info/www/bejne/anm6nIioms2LmLs

did you do it?
