Data on air temperature, relative humidity, and dew point in three housing modes in a building in a hot and humid area of Douala, Cameroon

data of the microclimate parameters of a building according to three housing modes in Douala, Cameroon. The microclimatic parameters were collected outside and inside three rooms for 365 days with a time step of one minute; for a total of 525,600 records of each parameter. The main data collected are: temperature, relative humidity and dew point. The experimental rooms are located on the first floor of a one-story building. The walls are built of 15 cm thick concrete blocks with 2.5cm layers of cement plaster on both sides. The data were collected using EXTECH®, RHT10 thermohygrometers. Data collected is grouped into 12-month series simultaneously in the three rooms. - Room S1 is open to the outdoor environment and is uninhabited - Room S2 is closed and is uninhabited - Room S3 is inhabited Each month includes a minute values of nine parameters: -The indoor air temperature, relative humidity and dew point of the empty open room S1. -The indoor air temperature, relative humidity and dew point of the closed room S2. -The indoor air temperature, relative humidity and dew point of the inhated room S3. -The outdoor air temperature, relative humidity and dew point of site EX.
