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