ESP8266 Community Forum

- Tue Aug 31, 2021 6:47 am #92172 I am new to MSP430 microcontroller, though I am coding MSP430 using Energia IDE which is similar to Arduino IDE.

My project is to build an "IoT Based Air Pollution Monitoring System"
I am taking input from the sensor (And I am done with the coding of this part it was simple) But now I have to put the data on Thingspeak server using ESP8266 and i dont have a clue how to do it.

I will be grateful if someone please provide me the code to connect ESP8266 to MSP430 and send data to Thingspeak! Please!!

Sensor is MQ135 which I have caliberated for CO2 reading. I have to connect ESP8266 to the MSP430 and send data to thingspeak!

PS: I tried going to 43oh forum (Energia Forum) but it is not allowing me to login for some reason the site is buggy!

There are plenty of examples on Google of using a MQ135 directly with a ESP8266!

- Fri Sep 03, 2021 11:27 am #92191 It is Compulsory and how can I connect sensor to it directly..... esp8266 is wifi module only...It is not NodeMCU

- Sun Sep 05, 2021 8:24 pm #92209 Apart from anything else (we don't know anything about your MQ/MSP setup, but I think that's not your main problem at this point).
Do you have the ESP working (like in: hardware-wise)?
Can you approach it (if in AP mode) or let it connect (and send bogus test-data) to a server (in STA-mode)?

Once you got the ESP covered, you can write a protocol that both the MSP as the ESP understand and you're done (to put it very simple).

But, to continue on Acme_UK's argument: the ESP8266 is a MCU (just like the MSP430) with a WiFi stack: it's not "Just a WiFi module".
FYI: a NodeMCU is just an ESP8266 on a more user-friendly board, nothing more, nothing less.

So the question remains: we do understand you have to use the MQ135, but why not connect it directly to the ESP and cut out the (MSP430) middle man?

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
