Temperature and RH mapping

dear all,
i need to do temperature and RH mapping in the ware house,
here i have query for the same…
1 how to decide quantity of sensor to be placed…
2 what shall be the time duration…some people says 3 days while some says 7 days…

I would place the sensors in all corners and any other critical spot, for example, close to the ventilation unit, close to any heat generating equipment, and in between any column or separating structures. The requirement of 3 or 7 days seems more dependent upon what type of warehouse it is, for example, if it is for APIs then, a longer time is better, but if its for medical devices 3 days should be good. And as usual, make sure to check any guidelines for your specific warehouse classification.

Hi

how to decide quantity of sensor to be placed- 4 corners & at centre ( worst case )
what shall be the time duration…some people says 3 days while some says 7 days- Worse season min 3 consecutive readings of 24 hrs

Also - here is a great link to Warehouse Temp/RH mapping:
