Sht3x

Description

The Sht3x object implements a driver for the I2C-based SHT3x humidity and temperature sensor. The parent of a Sht3x object has to be a corresponding I2cBus object.

All measurements are polled with high repeatability, leading to best accuracy. The measurement properties are updated approximately 20 ms after they got polled, i.e. a measurement has been initiated.

This object was introduced in InCore 2.0.

Properties

humidity

This property holds the last polled humidity value. When polling this property, the temperature is polled and updated automatically as well.

› Type:: Float
› Signal:: humidityChanged()
› Attributes:: Readonly, Requires Polling

temperature

This property holds the last polled temperature value. When polling this property, the humidity is polled and updated automatically as well.

› Type:: Float
› Signal:: temperatureChanged()
› Attributes:: Readonly, Requires Polling

Methods

pollHumidity()

This method polls the humidity property. It is called automatically when using a Polling property modifier on this property and usually does not have to be called manually.

pollTemperature()

This method polls the temperature property. It is called automatically when using a Polling property modifier on this property and usually does not have to be called manually.
