- Driver specific changes for updated button component in examples. - Updated the device_hal code for button component upgrade. - Updated the idf_component.yml of examples to use latest version of espressif/cmake_utilities.
Matter Sensors
This example demonstrates the integration of temperature and humidity sensors (SHTC3) and an occupancy sensor (PIR).
This application creates the temperature sensor, humidity sensor, and occupancy sensor on endpoint 1, 2, and 3 respectively.
See the docs for more information about building and flashing the firmware.
Connecting the sensors
- Connecting the SHTC3, temperature and humidity sensor
| ESP32-C3 Pin | SHTC3 Pin |
|---|---|
| GND | GND |
| 3V3 | VCC |
| GPIO 4 | SDA |
| GPIO 5 | SCL |
- Connecting the PIR sensor
| ESP32-C3 Pin | PIR Pin |
|---|---|
| GND | GND |
| 3V3 | VCC |
| GPIO 7 | Output |
NOTE::
- Above mentioned wiring connection is configured by default in the example.
- Ensure that the GPIO pins used for the sensors are correctly configured through menuconfig.
- Modify the configuration parameters as needed for your specific hardware setup.
