I will like to send the data to multiple recipients

Can an analog signal read from any input pin of Arduino be able to be sent on request through GSM or it must always be from a specific sensor?

I made changes to this line “SIM900.println(“AT + CMGS = \”+XXXXXXXXXX\””);” by removing the spaces and got the sms response.

Dear Sara
Thanks a lot for your tutorial.
It is very precise and it help me to sucess my application (Honey Bee monitoring), no yet finish but in process.
Thanks again.
Best regards

Hello. i have the same problem too.
I wanted to ask her if she managed to solve the problem that she does not receive sms.
I haven’t been able to yet

Hi.
You can learn how to get the temperature with the DS18B20 with the following tutorial.
https://randomnerdtutorials.com/guide-for-ds18b20-temperature-sensor-with-arduino/
Then, you just need to combine both sketches.
Regards,
Sara

Thanks for a nice project very useful.
My question is if I change sensor DHT to sensor DS18b20.
What does the code look like when I change sensors
