Simple ESP32 IoT Sensor Node Tutorial: WiFi Enabled MQTT Sensor Data Node

[@SideStreetLeather]

Thanks for the ESP32 video series. This is making the temp and weight measuring the logging of my school's beehives much easier to set up.

[@Europayacht]

Not one word to little nor to many. 100% on the spot. Thanks a lot!!!

Great video, it worked for me, I had a couple of issues, firstly I was just testing this with analogue input from a pin and some of the ESP32 analogue pins are disabled when wifi is operational. That took a while to sort! The only other issue was that I somehow didn't connect the nodes in node red, once that was sorted worked fine. I'll be using this for a battery operated weather station powered by a rather large 10w solar panel (since I want it on all the time) and a lipo . I've used Andreas Spiess's design with a power path. I'll be using the data in Home Assistant and also want to design a wall mounted retro display to show current weather with an arrow for wind direction etc. It's all a bit of a mammoth project since I knew very little when I started, this video has been a big help though.

[@LearnEmbeddedSystems]

I'm happy that this video played a part in your project! Best of luck with your project and would be interested to hear how the retro display turns out!

This is an awesome tutorial! I'm developing a system that monitors seeds that are planted and this is exactly what I needed. Thank you s much!

[@KeithHeilner]

Thumbs Up! New Subscriber. Fantastic tutorial. Direct and to the point.

[@brendanowen7563]

Thank you for such a clear awesome video. It was very well set out.

[@marelyruiz1321]

Thank you, you are awesome and your tutorial is amazing.

[@edinetgrunhed6000]

thank u i learn a lot thank any books from your channel

[@zf3d]

I vote to see similar project with LoRa such as TTGO :)

is gas heater affecting tem sensor? i have experiecne ens160 + aht2x sensor...which is about 3-4 C more than surrounding or compared to other sensor.

[@grottyboots]

Excellent video! I look forward to more!

[@timr86868]

I thought you were going to release a video about using the WiFi capabilities of the Pico W in C?

[@LegalizeAdulthood]

Since you've got the sensor and the server in the same room (and connected by USB cable), a good follow-on video would be showing how to connect the BME680 directly to the Pi and use a daemon to periodically read the sensor via the Pi's header pins.

[@LearnEmbeddedSystems]

Will look into it! Cheers for the suggestion :)

[@franciscosousa3730]

Am I able to create my own IoT app (web app in my case) and connect it to the MQTT server? If so, what programming language should I use to do it?

[@temyraverdana6421]

Thanks a lot for this amazing tutor

[@alexpr0gressive]

I would like to use the netsgpclient to collect data from my solar micro inverter. How can I have another client from netsgpclient to receive serial data via an lc12s 2.4ghz module? The two programs work by themselves but how can I merge them? I need a wifi mqtt serial gateway I guess.

[@iNireus]

Have you thought how you could do this with Alexa? Alexa replacing the pi part, on voice asking for temperature etc

[@zrxav]

Excellent video, thank you very much for your hard work! Could you please consider doing this IoT node but written in a Python-based enviroment? Such as Circuit python which already has Adafruit's libraries for most of the ICs/boards and protocols you're using or would you be so kind to point me towards a documentation that helps me make the JSON doc you've made in python? I have to be honest I've been following along your IoT server + IoT Node videos using an UnexpectedMaker S3 and I've been doing okay, I've collected the data from the sensors, connected to the wifi and published a message to the broker, but the only idea I have to submit the Json file is to create a dictionary, but afterwards I'm not sure I'll be able to publish it correctly nor I know how to monitor the Mosquitto container to see if the generic print I published is sitting where it should be, please help As for the server side is pretty straight forward and I just have to make sure the information is getting correctly to sensor_data DB before finishing up the Grafana setup

[@hieuao2509]

What about soil moisture sensor ? It’s not have library how i can do it

[@sanjeevjoshi6441]

it worked fine for a few hours and then started returning this error ( rc=-2Attempting MQTT connection...failed ) what might be the issue

[@terlumunjoseph6779]

hi i dont own a rapberry what other ways can i run a server instead of using raspberry

[@gregruthenium]

Can you please do a tute that includes both BME680 and SPS30 sensors with Node -Red and Grafana

[@LearnEmbeddedSystems]

I don't currently have any SPS30 sensors but I'll look into it.

[@gregruthenium]

@@LearnEmbeddedSystems How about If I send you one ;-)

[@JoseMartinez-ls8mj]

Thanks

[@codecraft-studio]

can I use esp8266 instead of esp32

[@k2nnethtan949]

Do you have micropython version?

[@AmitSharma-bm2qj]

Please make this architecture with ESP IDF and accelerometer sensor

[@norberthartmann5075]

nicht anzusehen - youtube baut jedes bild einzeln auf ..... :-( :-(

[@ArthurPage-z4q]

Kenton Shoal

[@AmitSharma-bm2qj]

Make this project using ESP IDF

wtf!?!? seems like the most over the top bullshit. like everything else in home assistant
