adafruit-circuitpython-HTU21D 0.11.9

CircuitPython library for HTU21D-F Temperature and Humidity Sensor.

Introduction

This driver enables you to use the Adafruit HTU21D-F temperature and humidity breakout with CircuitPyton.

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-htu21d

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-htu21d

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-htu21d

Usage Example

import time
import board
from adafruit_htu21d import HTU21D

# Create sensor object, communicating over the board's default I2C bus
i2c = board.I2C()  # uses board.SCL and board.SDA
sensor = HTU21D(i2c)


while True:
    print("\nTemperature: %0.1f C" % sensor.temperature)
    print("Humidity: %0.1f %%" % sensor.relative_humidity)
    time.sleep(2)
