SIM800L Sending Sensor Data to ThingSpeak | Arduino Multiple Sensors

#SIM800L #ThingSpeak #Arduino
In this video, I am going to show you, how to send multiple sensors data, to thing speak IOT cloud using SIM800L GSM and GPRS module and Arduino UNO. This project does not required, any Wi-Fi connection. I am using sim800l GPRS connection, to connect to the internet. I have used simple AT commands, to connect to the internet, and send the sensors data to cloud platform.

I am using 3 sensors in this project. DHT11 Humidity/Temperature Sensor, MQ2 LPG gas sensor and MQ7 Carbon Monoxide sensor. I am getting data from these sensors, and send them to Thingspeak using sim800l gsm module. After watching this video, you can get more ideas about Arduino Sensors projects.

sensor reading are showing in the serial moniter but the sensor data is not transmitting to the thingspeak website.

thank you for best explanation I have ever seen.

I want to remove the humidity sensor and add an Fire sensor. Where the GSM use to send alert message and I want to add a buzzer too....

Hello;
Thank you for your useful video all time, I have a question about adding to your code some lines that allow me to get data by sending SMS or making a call and at the same time sim800l module send data to thing speak.
I am looking forward for your answer.
Many thanks

Tengo una consulta, si mi compañía telefónica (WOM, chile) solo tiene APN, pero no tiene user ni pass, que pongo?

Hi Ahmad,
We apologize for my "translator" English
I have a doubt by the order of two commands of the code of the SIM800L-Multi-Sentor.ino file of this YT:
//
void init_gsm();
-> void gprs_connect();
-> boolean gprs_disconnect();
-> boolean is_gprs_connected();
boolean waitResponse(String expected_answer="OK", unsigned int timeout=2000);
//
I think the order of GPRS_Connec () and GPRS_Disconnec must be inverse, first disconnect and then connect and verify OK connection .
What do you think ?
Thanks

Need same tutorial for firbase sir using multiple sensors please .... Thanx in advance

Hi sir, I am using RFID card reader on my Arduino project so when you tap the card, it counts up by one and when the same card is tapped, it reduces the count by one. i want to send this information to ThingSpeak but when I use those AT commands, the RFID reader stops working. What could be the problem?

Hi i wanna ask wheather the api keys and channel id permannet means can i program once and play system without laptop. Or i hav to use usb interface everytime can it b laptop free system so i can run it through jst adapter anywhere

[fernandohood]

Not much detail on how to use the url and key and field info in the code.

É possível você fazer uma lógica de arduíno com sensor e pushbotton , apertar push bottom call in phone e sendo SMS?

[fiqianarofi]

thanks making same with using sensor jsn srt04 ..please..

Hello sir my sim 800l not working with esp32 please provide Simple AT command skatch so i can check why its not working

[yawarsaeed]

Can you please share which MQ series sensor should I use to detect Sui Gas leakage we use in our kitchen burners. I have already tried MQ-2, MQ-4 & MQ5 but none of them detect the Sui Gas although all of these detect gas from cigarette lighter gas .

[rxcvrdosxni]

hello sir. i have used the code and wiring as in the youtube video. my serial output mimics yours except for the +HTTPACTION: 0, 606, 0
output, however data is not being shown on the Thinsgspeak server. please help

Is it possible to use both Wifi and GSM services simultaneously in ARDUINO/ESP module?

[bisnusikder]

Ac main power line on off send sms sim800 It would be great if brother could make a project about it

[s.husain]

Thank you so much sir ....how to send float value like temperature 24.2 and humidity 64.5 means send decimal value also

[HarishKumar-uyml]

Unable to get the value on thingspeak inspite of the connection being established, its get displayed on serial monitor

[saadelm]

Great job... Plz. Haw i can change the sender phone number (cmgs) just with sms... Without code? Thanks
