Readings Dataset

Description

Dataset containing relative humidity, barometric pressure, ambient temperature and other data obtained from a BME280 sensor connected to a Raspberry Pi.

Usage

data(readings)

Format

A data frame with observations captured at regular intervals of time and ten variables.

Details

The data frame includes the following variables:

reading_id

Unique character string generated by the BME280 sensor for a reading.

date_time

The date and time of a sensor reading.

month_of_year

The month of year derived from the date_time column.

day_of_week

The day of week derived from the date_time column.

hour_of_day

The hour of day derived from the date_time column.

interval

The time difference between a sensor reading and the prior sensor reading, expressed in minutes. Note that sensor readings were taken initially at five-minute intervals, then increased to one-minute intervals. Extremely high humidity levels occasionally caused the sensor to stop functioning, requiring a reboot of the Raspberry Pi. These breaks in readings are reflected in some non-standard intervals.

degrees_celcius

The ambient temperature expressed on the Celcius scale.

degrees_fahrenheit

The ambient temperature expressed on the Fahrenheit scale.

barometric_pressure

The atmospheric pressure expressed in hectopascal units (hPa).

relative_humidity

The concentration of water vapor in the air expressed as a percentage, indicating the present state of absolute humidity relative to a maximum humidity given the same temperature.

state

Categorical variable; identifies the state and location of a dehumidifier with three possible values: N indicates dehumidifier is not running, D (direct) indicates dehumidifier is running and present in the same room as the BME280 sensor and I (indirect) indicates the dehumidifier is running and present in a room adjacent to the BME280 sensor.

room

Categorical variable; identifies the location of the sensor with two possible values: UB indicates the sensor location is in the second floor bathroom and UH indicates the sensor is in the second floor hallway.

peak_rh

Boolean value; indicates whether a reading is considered a peak relative humidity value. For details on how peak values are determined, refer to the documentation for the find_peaks function.
