To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Raspberry Pi Blockset / Sense HAT

Description

Measure the relative humidity and the ambient temperature using the Humidity sensor (HTS221) on board Raspberry Pi^® SenseHAT.

Note

To generate C/C++ code for this block, you must have an Embedded Coder^® license.

Ports

Output

Humidity — Relative humidity output port

scalar

The relative humidity measured in percentage from the Humidity sensor.

Data Types: double

Temperature — Ambient temperature output port

scalar

The ambient temperature measured in degree Celsius from the Humidity sensor.

Data Types: double

Parameters

Board — Model of the Raspberry Pi board to which the SenseHAT is connected

Pi 2 Model B (default) | Model B Rev1 | Model B Rev2 | Model B+ | Pi 3 Model B | Pi 3 Model B+ | Pi Zero W | Pi 4 Model B | Pi Zero 2 W | Compute Module 4 | Pi 5 Model

Select the Raspberry Pi hardware to which the SenseHAT is connected.

Sensor output data rate (ODR) — Rate at which the sensor measures data

12.5 Hz (default) | 1 Hz | 7 Hz

The rate at which the Humidity sensor measures relative humidity and ambient temperature.

Sample time — Frequency at which data is measured data is read from Humidity sensor

0.1 (default) | scalar

Specify how often this block reads the measured data from the Humidity sensor.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"sensehatlib/HTS221 Humidity Sensor"

Example: add_block("sensehatlib/HTS221 Humidity Sensor","myModel/myBlock",MakeNameUnique="on")
