How to make a Temperature, Pressure, Altitude Logger [Esp8266, WiFi, Arduino]

This tutorial shows how to make a basic logger using WiFi and Adafruit MQTT. It is based on the cheap WeMos (Esp8266) micro controller with an air pressure/temperature and an OLED shield. It is programmed with an simple Arduino sketch and put in a 3D-printed case. I also explain how the altitude is calculated from airpresure. This logger should be doable for beginners, since not much soldering is needed. Enjoy watching!

Awesome video with great fun. What a commitment to climb up a 2000m mountain just to test the sensor. From the dawn of mankind: Impressive.

Awesome that you can do it full time, and beautiful nature you got there.

Nice video! It's very common go hike at places where we don't have signal coverage. Would be nice a 2.0 version of this project where we can store data on a sd card or even on eproom.

Really enjoy your videos. Keep up the great work!

I really love how you show the code in close-ups so clearly! I wish everyone would do that. Thank you! #giveaway black (but I'm not picky any color would be fantastic)

Find deine Videos echt klasse mit deinem Humor :) Sah aus als würdest du aus Bayern kommen, da bin ich auch ab und an ;)

Well much to my good wife of 48 years dismay, I went ahead and ordered the parts to build this unit. That was back on the last week of April. Now I have the ESP8266 (cute little bugger!) and the sensor (funny bigger then it's cousin for large use) but the screen is listed as en-route to the USA! Perhaps they shipped her via the proverbial "slow boat from China!" Ah well, today I decided to try and use a different display that I have instead, see if I can make that work. After all I will need something a bit larger to be able to see it on my dash with my 67 year old eyes looking through eye glasses that make a coke bottle look thin.

Awesome... Great Video and Project 🤓 Looking forward for "More'er" Videos 😉

Nice! How much flashing memory is available on these Esp8266 ? I am BFROBOT Beetle instead. Power consumption is also a consideration.

Would GPS be more precise for altitude? Perhaps an interview improvement could include a gps & atmospheric pressure sensor data logger? Nice video. Thanks

[MyBigThing]

I wonder how good this would work in an RC airplane or quadcopter?

If it's a bitluni's video out notification, then you will see ESP8266 for sure, you are an ESPecialist. #giveaway

Sorry if my question kinda silly.
If there isn't connection(I assume you need internet connection), is the temperatur/pressure/altitude still shown ?
Is the connection only for logging purpose ?
Thanks

Not sure if you would be interested, but ... How hard would it be to also add GPS to this? I drive a lot and would like to track my location and altitude. I already have an Arduino UNO with an SD shield. Just asking?

Wonderful view. What places? Where are you? Greetings from Colombia South America

Can we use this for checking maximum altitude of DIY rocket.
