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.

Example¶

import InCore.Foundation 2.5
import InCore.IO 2.5

Application {
    FtdiI2cBus {
        Sht3x {
            id: sht
            address: 0x44
            Polling on temperature { interval: 100 }
            onTemperatureChanged: console.log(Math.floor(temperature*10) / 10, "°C -",
                                              Math.floor(humidity*10) / 10, "% r.h.")
        }
    }
