micropython-sht31

This repository contains a MicroPython "driver" implementationforo the SHT31 temperature and humidity sensor from Sensirion.

Currently only a reasonably small subset of the features the sensor is implemented.

Implemented

• Read the temperature and humidity at different "repeatability" (accuracy) settings. With celsius and fahrenheit values.
• Only single shot data acquisition mode

Not yet implemented

• Continous (periodic) temperature acquisition and the corresponding break/stop command
• CRC check of the sensor readings
• Temperature alerts
• Resetting the sensor (nRESET pin)

Example code:

from machine import Pin, I2C
import sht31

i2c = I2C(scl=Pin(5), sda=Pin(4), freq =400000)
sensor = sht31.SHT31(i2c, addr=0x44)

sensor.get_temp_humi()
