Python library for TE HTU31D temperature and humidity sensors


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-htu31d

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

sudo pip3 install adafruit-circuitpython-htu31d

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-htu31d

Usage Example

import time
import board
import adafruit_htu31d

i2c = board.I2C()  # uses board.SCL and board.SDA
htu = adafruit_htu31d.HTU31D(i2c)
print("Found HTU31D with serial number", hex(htu.serial_number))

htu.heater = True
print("Heater is on?", htu.heater)
htu.heater = False
print("Heater is on?", htu.heater)

while True:
    temperature, relative_humidity = htu.measurements
    print("Temperature: %0.1f C" % temperature)
    print("Humidity: %0.1f %%" % relative_humidity)
