This is a P8X32A/Propeller, P2X8C4M64P/Propeller 2 driver object for the Sensirion SHT3x (30, 31, 35) combination temperature and relative humidity sensors.
IMPORTANT: This software is meant to be used with the spin-standard-library (P8X32A) or p2-spin-standard-library (P2X8C4M64P). Please install the applicable library first before attempting to use this code, otherwise you will be missing several files required to build the project.
- I2C connection at ~30kHz (P1: SPIN I2C), up to 1MHz (P1: PASM I2C, P2; max tested speed 840kHz)
- Measurement in one-shot (with clock-stretching) or continuous modes
- Supports all three measurement repeatability modes and five data rates
- On-chip heating element operation
- Reading the sensor's serial number
- Supports alternate slave address
- Set interrupt thresholds
- Optional reset pin
P1/SPIN1:
- spin-standard-library
- 1 extra core/cog for the PASM I2C engine (none if the SPIN I2C engine is used)
- sensor.temp_rh.common.spinh (source: spin-standard-library)
P2/SPIN2:
- p2-spin-standard-library
- sensor.temp_rh.common.spin2h (source: p2-spin-standard-library)
