SHT4X: High Accuracy Digital I2C Humidity Sensor
|
|
#################################################
|

|
Description
|
|
***********
|
|
|
|
This sample application periodically reads the ambient temperature and humidity
|
|
from an SHT4X device. The result is written to the console.
|
|
|
|
The SHT4X sensor has an optional heater that can be useful for specific
|
|
environments or applications (refer to the datasheet for more information).
|
|
To utilize the heater, check the Kconfig options for this application.

Wiring
|
|
******
|
|
|
|
This sample uses the SHT4X sensor controlled via the I2C interface.
|
|
Connect Supply: **VDD**, **GND** and Interface: **SDA**, **SCL**.
|
|
The supply voltage can be in the 1.7V to 3.6V range.
|
|
Depending on the baseboard used, the **SDA** and **SCL** lines may require Pull-Up
|
|
resistors.
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
This project outputs sensor data to the console. It requires an SHT4X
|
|
sensor. It should work with any platform featuring an I2C peripheral
|
|
interface. This example includes a device tree overlay
|
|
for the :zephyr:board:`blackpill_f411ce` board.

SHT4X: 23.66 Temp. [C] ; 32.16 RH [%]
|
|
SHT4X: 23.63 Temp. [C] ; 30.83 RH [%]

|
The datasheet states that the sensor measures temperature and humidity in degrees Celsius
|
|
and percent relative humidity respectively.
