sending sensor values on GSM using SMS
I am working on a project which involves sending sensor reading on GSM network using SMS. I am able to send normal text messages.
I am limited to const char* variable type. sensor reading from temperature sensor LM75B (temp sensor on application board) is a float variable. Is there a way to convert variable type?
