How to use BME280 Temperature, Humidity and Pressure sensor with Arduino

[@LucasLGMarques]

My god this dude is thorough! I stated whatching expecting just another "basic" tutorial without much information and now I know how wrong I was... Congrats for the teaching skills!

[@robojax]

Thank you. I am glad you found it useful.

[@joelgalbraith7219]

This video helped me with a school IoT project. Thank you.

[@robojax]

Glad it helped!

[@F111BMATHIS]

I had given up, but then came back and tried again :), finally working. I have the blue sensor and the pins don't match, but swapping A4 & A5 worked this time. A4 = SDI, and A5 = SCK

[@kamilzdunczyk2245]

excellent tutorial. You explain everything fantastically, thank you very much. I really like this channel

[@robojax]

Happy to hear that!

[@borsi99]

Thanks for your video which are always interesting. Please could you show how to put out the values on LCD 20x4? Most time you are showing serialprint only. Thanks a lot✌🏼Boris 🇨🇭

[@robojax]

Just search my channel for LCD

702 is not a regulator, it is a Dual N-Channel MOSFET for i/o logic level shifting from 5v to 3.3v.

[@robojax]

Hi, Thank you for pointing that out. I just check it and could not find anywhere the 702 as mosfet. Adafruit uses two MOSFETS BSS138 for level shifter on the module and shown on the schematic here learn.adafruit.com/assets/26693 (datasheet for BSS138 www.onsemi.com/pub/Collateral/BSS138-D.PDF) and if you open the schematic on separate tab cdn-learn.adafruit.com/assets/assets/000/026/693/original/sensors_sch.png?1437773082 you will see a 5 pin chip MIC5225-3.3 which is a 3.3V regulator where you can see the datasheet here cdn-shop.adafruit.com/datasheets/mic5225.pdf

[@ascuber4650]

​@@robojax Hi, I'm not talking about Adafruit board but about board you're reviewing. At 2:42 the 6 pin SOT-363 chip on the right marked 702 is the dual MOSFET. Datasheet is here (marking is on the page 2): www.gs-power.com/db/pictures/modules/PDT/PDT060207001/DS_GSM7002T_Rev1.2.pdf Thanks.

[@robojax]

thank you. yes you are right. it makes sense at 2:43 at the middle you see the 103 x3 resistors that is used with the logic level converter. I'll see if I can remove that portion . thanks for the comment and pointing the error.

[@ValentinusChrysan]

Can hpa be changed to pa?

[@robojax]

1 hPa = 100 Pa, so if ou want it in "pa" just divide it byh 100. it is very sijple. let' say we have a variable "age" and it has value of 10 and you want to divide it by 2, simply write age = age/2; or age /=2; now age will be 5. Do the same in this code.

[@robojax]

if you want to learn about variables, there is my video which is part the course kzbin.info/www/bejne/pGHdZ5mgrNxrm6M

Hi bro;It is great tutorial,thank u so much ! Where can I find library for BME280 ?

[@robojax]

You are welcome. Under the video in the description There is link to library and other resources for this video.

You are the best.

[@robojax]

Thank you . So are you.

[@robojax]

Thank you for letting me know. I can't do anything about it except to clip that portion out.

[@alexandrefranca7445]

Hi there. I accidentally burn the capacitor connect between VIN& GND befor the 662 voltage regulator while soldering. Do you know the value of this capacitor so I can try to change it and see if the BME 280 is still working? thanks in advance. Alexandre

[@robojax]

Hi, the capacitor value should not be critical. it is is just a filter. most of the modules are replica from Adafruit or Sparkfun. you can see schematic here cdn.sparkfun.com/datasheets/Sensors/Weather/SparkFun_BME280_Breakout_v10.pdf

[@hamasahmad8444]

Is there any way we can save the data? Also can u tell me about any software where we can simulate this to check this ? Thanks

[@robojax]

Salaam alaikum, here is how to save on microSD card kzbin.info/www/bejne/ipXYhIKOa6iAqJY I don't know any simulator.

[@marciliogr426]

Can we change the sea level preasure to increase the precision of altitude?

[@robojax]

You can. But remember altitude is approximate. I have provided the datasheet. Read that please.

[@Ilikeridin]

Great tutorial, thank you. The temp is reading 1 degree high. Is there a way to write code to always subtract 1 degree?

[@robojax]

You are welcome. Yes you can change the value. find this line: float temp = bme.readTemperature();// read temperature and immediately under that put: temp =temp + 1; this will add 1 into the "temp" which is the variable holding the temperature. or subtract with -

[@Ilikeridin]

Robojax thats brilliant, thank you. I’ll try that later as I’ve not managed to get it to work.

[@Ilikeridin]

I’m already using float as the project includes rf24 modules. Would it have to be a separate float command?

[@uttamdutta3664]

is it possible to measure the altitude by bme280

[@robojax]

I have provide the link to datasheet. Check that out. I have new video on bmp380 where you can measure appropriate altitude.

[@raiyanamiruddin4741]

Hey I have one question I am trying to find one sensor that can detect human presence from like 3-6 feet do you know any sensors that can fulfil this task

[@robojax]

Hi, very hard topic. detecting a living thing can be done by temperature, motion, shape and many oher factors like breathing etc. this product sold in this video is called body motion detector kzbin.info/www/bejne/nmqtdZ-HjdWcaNk you look at .But for proper detection, you need motion sensor and thermal sensor to combine and get about 60% accuracy. for 90% accuracy or higher, you need camera to detect shape. then thermal camera and motion sensor get assurance that the object is human. Good luck

[@VANTABL4CK]

Hey, I don't know why but it seems they removed readHumidity from the newer version of this library

[@robojax]

I always save the library and provide it as zip. So try getting that then.

[@robojax]

Thank you.

[@conradsinsua7415]

thanks for the video, i hv a similar sensor but had a close look on the sensor and it doesn't have the same marking on the sensor, mine has 807ur, reason for asking is i bought 2 and i got one to work and after one hour it stop working,

[@robojax]

You are welcome. Did you check if yours is 3.3V? if you connect it to 5V it will die. Check it or connect the other at 3.3V and if it works, then keep using only 3.3V.

Hi. I have the same module that you have. But are those extra 3 pads for. I bought it as bmp. And you saying its bme. Which one is right. Because i need bmp for my project.

[@robojax]

Hi, I have video both on BME280 and BMP280 with code. the best option would be follow both video and upload the code and see which one works. Just pay attention to the wiring so you don't mix the GND and VCC. Here is how to find Specific KZbin Video in a channel bit.ly/findKZbinVideo

@@robojax thanks. It's just bme won't work on my board for some reason.

If you do proper wiring it should work . It uses I2C communication and just connect it to A4 and A5 watch the video and try both projects. Run first I2C scans to see if you get the address.

Hi I have a problem with this kind of sensor. When I use the I2C scanner it return me the address 0x76. But When I use your sketch or any other that use this sensor, returns this "BME280 test Could not find a valid BME280 sensor, check wiring! " I don´t know if I have something wrong or simply the sensor is broken. Please help me. Regards

[@robojax]

it seems you have not installed the library. or the wires are loose. check it again. Thank you for not skipping the ads and keep watching it. This will help me a lot.

@@norielhurtado1082 I have this same issue. Except when I run the I2C scanner, it doesn't return an address. No idea how to fix, someone please help

@@norielhurtado1082 Just rename the library, his code is wrong. Before download, try to compile

[@norielhurtado1082]

Ok here is what I was done yo dix this In code line number 44 Status =bme.begin(); You must write the sensor address, in my case the address is 0x76. If you aren’t sure of which is your sensor address first run an i2c scanner sketch to get your sensor address. Returning to the main code the line 44 change to this: Status =bme.begin(0x76); And the sensor began to send the measuring data. I hope it works for you people and continue learning arduino like me.
