As Nelokin has already answered, the 48 hours warming up is necessary for the first time.

But the pre heating for 3 mins is needes everytime you use it. This is true for pretty much every Co2 sensor we use.
By the way, if you're interested in making a compact PCB based on Co2 sensor and Arduino, you can consider making a design like this:

bidrohini.bidrohini Hi
Are you asking for Gravity: Analog Electrochemical Carbon Dioxide Sensor (0-10000 ppm)(SKU:SEN0159)?
For the first time usage, you have to warm it up for 24 hours.
After that, you can use your sensor 3 minutes after pre-heated, the data will be more accurate.
Hope it can help.
