Introduction

A collection of CircuitPython helpers for calculating Dew Point, Heat Index, and for converting temperature units..

Dew Point calculates dew point temperature from measured temperature (Celsius) and humidity (percent). Returns the calculated dew point (Celsius) and summary description. Detailed description is provided if verbose=True. Dew point value is constrained to the range of 0 to 40 (Celsius).

Heat Index calculates heat index temperature from measured temperature (Celsius) and humidity (percent). Returns the calculated heat index (Celsius) and summary description. Detailed description is provided if verbose=True.

Unit Converters convert values between Celsius, Fahrenheit, and Kelvin.

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install cedargrove_temperaturetools

Or the following command to update an existing version:

circup update

Usage Example

from cedargrove_temperaturetools.dew_point import dew_point
from cedargrove_temperaturetools.heat_index import heat_index
from cedargrove_temperaturetools.unit_converters import (
    celsius_to_fahrenheit,
    celsius_to_kelvin,
)

# Measured temperature and humidity
TEMPERATURE = 24  # Degrees Celsius
HUMIDITY = 50  # Relative humidity in percent

dew_point_temp, description = dew_point(TEMPERATURE, HUMIDITY)
print(f"Dew Point = {dew_point_temp} {description}")

dew_point_temp, description = dew_point(TEMPERATURE, HUMIDITY, verbose=True)
print(f"Dew Point = {dew_point_temp} {description}")

heat_index_temp, description = heat_index(TEMPERATURE, HUMIDITY)
print(f"Heat Index = {heat_index_temp} {description}")

heat_index_temp, description = heat_index(TEMPERATURE, HUMIDITY, verbose=True)
print(f"Heat Index = {heat_index_temp} {description}")

print(f"Measured Temperature (Celsius) = {TEMPERATURE}")
print(f"Measured Temperature (Fahrenheit) = {celsius_to_fahrenheit(TEMPERATURE)}")
print(f"Measured Temperature (Kelvin) = {celsius_to_kelvin(TEMPERATURE)}")
