This is a getting started series for the products found on my online shops!
In this video, we setup the BME680 breakout board with an ESP8266 NodeMCU as well as an Arduino Uno to collect temperature, humidity, pressure, and air quality (VOCs) data:
amzn.to/32FIs1y
These environmental units are fantastic as they pack 4 highly precise sensors into a single package!

Cisco man how do we do it he air quality ppm from the sensor I know you use the gas and humidity but how? I don’t. Understand the Kohms part.

Hi, i tried this sensor some times ago, but the gas reading were very unreliable. It was contiuosly growing. Also temperature reading were influenced from the gas sensor unit that requires to warm up the sensor. Could you monitor your sensor in continuos mode for some days to verify if yours one have the same behaviour?

@chuckvanderbildt 4 роки тому

As far as I can tell, the onboard temperature sensor is really meant for compensating the humidity/gas/pressure sensors. The datasheet does mention that the reading will be above ambient due to self heating. It's misleading that they market it as a four-in-one sensor. For accurate room temperature sensing you kind of really need to add an additional ds18b20 or something. As for the tvoc part, it has all sorts of auto-calibration/baseline functionality to compensate for drift, which makes it useless for absolute measurement if you ask me. It apparently also needs a burn-in period when new, and every time it's switched on.

Interesting to know, thanks for sharing. Sensors based on MOx are inexpensive, but unfortunately 'unreliable' (hard to calibrate) and can only be used to monitor relative changes in gas concentrations. You're right in that it shouldn't continuously increase(!) Certainly, I want to run a few over a week and plot the results-I'll make a video of the process!

@javierpallalorden 4 роки тому

@@datasith Would be very interesting to see your results, thanks, gracias!

@gglovato 3 роки тому

the temperature is sensed first, so it's NOT affected by the MOx heating, check the datasheet for the BME680 for the reading process. For example, for the BME280 it does T->H->P, thus temperature is sensed when cold. You should also NOT use these sensors in "normal" mode(continous reading) but in forced mode(forced reading, then sleep), thus you eliminate the self-heating

@igorbisori5117 3 роки тому

@@gglovato and @Marco Buzzanca Were you able to get an iaq accuracy of 3? After 5 minutes of operation I get the value 1 without ever reaching 3 (sometimes the value drops to 0). I use D1 mini and BME680

@ranieldenicen.marpuri6544 4 роки тому

how does it measure altitude ? and if the others say that VOC sensor affect the temp sensor would it render this to be useless ? or is there a solution to this ? im as excited as you to find out the answers to all these questions.

@datasith 4 роки тому

Pressure varies with altitude, and there's a standard conversion to calculate one from the other. I will run a few temp sensors alongside the BME680 and post the results. Stay tuned!

@ranieldenicen.marpuri6544 4 роки тому

i see, hence the "approximation of altitude" . awesome, again excited to see the results of your findings.

@tylermarlar1278 4 роки тому

Hi, I just tried using this sensor but I am unable to see an readings in the serial monitor. I am using 115200 baud as you did in this video. The serial monitor will only print "BME680 Test" and then nothing happens. Do you have any suggestions? Thank you!

@datasith 4 роки тому

It looks like your code is getting stuck at line 39. You see the debug message, but the code stays in the while loop due to not finding the sensor. As suggested in the code, double check your wiring :)

@Ed19601 4 роки тому

Further to what others have said about the gas sensor, i think it is quite useless: as output it comes with a total meaningless number. That does not change the fact, you made a great video

@datasith 4 роки тому

Thanks for the kind words, I’m glad you liked the vid. Yes, most of these MOx-based sensors are incredibly hard to calibrate as their measurements vary widely w/ changes in temperature, humidity, and also degrade with time. They work fine for detecting ‘significant’ changes in concentration, but getting meaningful values (ppm) isn’t possible. In the $10~$20 range it is a good deal to get 3 or 4 environmental measurements in a single package for hobby-grade projects!

@Ed19601 4 роки тому

@@datasith definitely, still, I drew the line at the bme280. Only gas i am usefully measuring is co2. With a winsen mhz19, still 'fairly' cheap :-) But you definitely explained very well for someone e who is using the bme680

@datasith 4 роки тому

I want to do a comparison video between a few CO2 sensors, and yup it boiled down to the MG811, MH-Z19, and a cheapy ol’ MQ-135. I was definitely impressed with the MH-Z19. Hope to finish it soon!

@SolarWebsite Рік тому

Yeah the words "cheap" and "gas sensor" don't belong in the same sentence. I've heard someone say cheap gas sensors are better employed as random number generators....

I am using the same CJMCU-680 ( which you are using) . But the Device is not working. I Scan with I2C scanner but no device or address is found. Do i need any Pull up register with it? I am using Esp32.

@datasith 3 роки тому

I typically don't use pull-up resistors and it works okay. Double check your I2C connections, it's gotten me more than once. Make sure you're using the default I2C pins: SCL @IO22 and SDA @IO21.

How to detect Particular Smell using BME680

@billybbob18 2 роки тому

You would need TONS of sensors for that.

@ytrew9717 4 роки тому

Sorry, I don't understand what you say at 4:03, "the defaut [???] address" . What is it (and, optional ― I will google it―: why)?

@datasith 4 роки тому

The "???" was "i-squared-c" typically written "I2C". I2C is the communication protocol used by the BME680. this communication protocol depends on each device having an address. the one for the sensor is 0x77 by default, but you can change it to 0x76 in case you had another device already with that address and couldn't be changed!

@@egymakers7183 depends how many features you need. If you just want to visualize data and actuate devices, it should be done within a day's worth of work (8 hours). Other things like storing data, supporting multiple sensors/actuators, etc., add to that timeframe.
