Hope you people have understood that I know nothing about this SPI stuff.
Only the sensor´s datasheet can tell what data you have to send to the sensor.Is it mandatory to transmit data serially to the slave via MOSI pin?
This depends:After what duration should the master re-read the sensor for the next temperature reading
* only the datasheet can tell.Can I do so after 10-20 clock cycles of finishing the previous read operation?
--> Do this on your own. We don´t know the specifications for your tempersature sensor., We don´t know where you live, We don´t know your budget.Pls. suggest a common SPI temp sensor (common = cheap; easily available
Funny. Do you know about any electronic sensor that is known to be "not workable"?and workable).
This depends:
* on your application --> how often you you want the temperature to be read?
* on the sensor --> read the datasheet
* only the datasheet can tell.

For sure you are free to use a second clock source. Like from an external RC with a clock frequency of just 1 Hz.

This second clock can't be generated internally. You need to generate it externally. It's not important how.For sure you are free to use a second clock source. Like from an external RC with a clock frequency of just 1 Hz.
Or an external clock divider...or...
