connect SIM900 and CJMCU-833 AMG8833

I'm planning on doing a project at school, but in order to do it, I want to connect (X2) "CJMCU-833 AMG8833" to a "SIM900". I want to use the thermosensors to detect heat every 30min and if it detected it it will send a message or a phone call to the registered numbers. The question now is it possible to do it, and how?

Yes, sure. I don't know the temperature sensor You intend to use. I have used temperature sensors but not this type. One question I have is what Your intension is regarding the powering of Your measuring unit.
