WebThing Motion Sensor is prepared for ESP32 CPUs and uses esp-idf environment (freeRTOS and LwIP included).
It reads the output (default GPIO18 pin) from the motion sensor and communicates with the WebThings Gateway via the WebThing API.
The example motion sensor is here.
Requires:
- web-thing-server from
webthings-components
webthings-node-example-project
or
This webThing has the following properties and one event:
- motion - motion detected
- alarm ON/OFF - alarm activation, a notification is sent each time motion is detected
- counter-1 - motion detection counter, 0..5000
- last alarm - time of the last sent alarm (notification)
- counter-2 - alarm counter, 0..99
- alarm notification (event) - sent when motion detected and alarm is activated
Example event log is shown below.
See webthings-empty-project and follow steps described in Build webThing Device chapter.
In point 5 download webthing-motion-sensor repository. In function init_things() call init_motion_sensor() and include webthing_motion_sensor.h in your main project file.
