ESP8266 DHT11 SIM800L | GSM Based Temperature Monitoring with NodeMCU

This project is based on GSM Based Temperature Monitoring with NodeMCU DHT11 and SIM800L. You can request sensor data (DHT11) with SMS by using NodeMCU ESP8266. In this video, I am going to request the temperature and humidity from a DHT sensor by sending an SMS and then this system responed back with the required data (you will receive temperature, humidity and heat index on you phone by sms). I am using SIM800L GSM Module. When you send an SMS to the system (ESP8266 with DHT11 and SIM800L), it replies with temperature, humidity and heat index readings from DHT11 temperature and humidity sensor.

Warning: In some countries it is required to register gsm module from govt authorities before using it. So, get proper understanding of govt laws related to gsm technologies.

Very Nice, real Teacher Lucky from sri - lanka

Hello! I would like to create a similar project, also using an ESP8266 and a SIM800L, but I would like to include an MPU6050 for fall detection instead of DHT11. Could you help me with some advice, please? I can't figure out how to power the SIM800L since it needs a higher voltage than the MPU6050 and ESP8266.

[MrFloppy]

Thank you very much for your wonderful tutorial. I have a question. How is the ESP8266 powered? From what I see in the video and in the diagram, the battery is only connected to the SIM800L.

[xiomai]

I wonder how to do a connection or a wiring diagram of esp8266 as the main board and is connected with gsm sim900a and a flame sensor. Where in the values of the flame sensor in the database will be shown or projected to our website.

[altanigrum]

SIM800 connects to the network (blinks after three seconds) but doesnt do any serial communication with esp8266. Nothing gets printed on serial monitor and sim800.available is always zero. Any ideas how to fix this?

[kimjasperanaque]

Sir why does it displays error on the serial monitor when it initializes the SIM 800l?

[faizanalam]

To send a message with the gsm module we need to have balance in sim ?

SIR, i done your esp32/sim800l/neo6m firebase project ... yesterday its working fine... but when i try to do it todat... i saw the AT+CIPSHUT command always occuring... can u plz explain ... why its

[harvindertiwana]

Please make a tutorial how can I send this data to firebase (requested previously also). ...The great thing about your tutorials is that you put the download link of the concerned libraries within the code. Try to add Urdu audio for better explanation. Thanks for your worthy tutorials.

Just like yo say 💭 but didn't work it's blink every 3 sec but, at command ok not display on serial monitor?

How to charge battery use for gsm module

[riandutra]

How many hours does it last with just one battery?

[vidhayakg]

Sir kindly make a video of how we can send data to the cloud server by only using GSM Sim900a or any other gsm module
I've tried but it's not working I can make calls from mobile to gsm but from gsm to mobile calls are not happening.
I think there is an issue with the API key kindly help me.

[venikurnia]

Nice. Thank you for making this video I am so glad for this 😍

The massage i get back "<<Content not supported.>>"

[ashyaziz]

Nice content! But Please can u do 1860 battery, sim800l and nodemcu esp8266. The function is I will text a code and then the GSM will text me back about the battery percentage

[mohammadatiah]

Hello brother, please help me, it does not ring for me, what is the solution?
