HTS221 Humidity Sensor
Measure relative humidity and temperature from HTS221 sensor
Simulink Coder Support Package for STMicroelectronics Nucleo Boards/ Sensors
Embedded Coder Support Package for STMicroelectronics Discovery Boards/ STM32L475-Discovery (B-L475E-IOT01A)
The HTS221 Humidity Sensor block measures relative humidity and ambient temperature using the HTS221 humidity sensor interfaced with the Nucleo/STM32L475-Discovery board. This sensor comprises of a sensing element to measure the relative humidity and temperature.
You can also select an output data rate for the measured values in the block.
Humidity — Relative humidity as measured by HTS221 sensor
The block outputs the relative humidity in percentage (%).
This output port appears only if you select the Humidity (%) parameter.
Temperature — Temperature measured by HTS221 sensor
Temperature (in ℃) measured by HTS221 sensor connected to Nucleo/STM32L475-Discovery board.
This output port appears only if you select the Temperature (℃) parameter.
Status — Status of pressure and temperature measurements
Status of pressure and temperature measurements, specified as a 1-by-2 vector.
0 indicates that the data read is new,
indicates that the data read is not new, and
-1 indicates that the
corresponding output is not selected.
This output port appears only if you select the Status parameter.
I2C module — Specify I2C module
2 (default) |
Specify the I2C module on the board. The I2C bus frequency, serial clock (SCL) pin and serial data (SDA) pin are taken according to the corresponding I2C module entry in the configuration parameters.
Humidity (%) — Set output port for reading humidity
on (default) |
Select this parameter to set Humidity as one of the output ports.
Temperature (℃) — Set output port for reading temperature
on (default) |
Select this parameter to set Temperature as one of the output ports.
Status — Set output port for obtaining status
off (default) |
Select this parameter to set Status as one of the output ports.
Output data rate (ODR) — Rate at which humidity and temperature data is sampled
1 Hz (default) |
7 Hz |
Select the output data rate at which humidity data is sampled.
Sample time — Time interval to read data
-1 (default) | positive integer
Specify how often this block reads the data from the HTS221 sensor. When you set this parameter to -1, Simulink determines the best sample time for the block based on the block context within the model.
