This sensor allows you to detect animals' movement, usually humans' movement within its detection range. Just connect it to the NyBoard and program it, and when anyone moves within its detection range, the sensor will output a high potential on its SIG pin.
With NyBoard V1_*, you can choose Arduino Uno.
Connecting to the NyBoard with wire as shown in the following picture:
For specific use, the end connected to the sensor can be fixed on the robot's head (included in Bittle's mouth or attached to the top of Nybble's head). Of course, you can also use your creativity to meet your needs.
If you want to test a PIR motion sensor's function alone or learn more about its principles. You can use the Arduino IDE to upload the demo sketch(test_Touch_Reflection_PIR.ino):
You can use the within the Petoi Desktop App.
You can use to upload and modify the source code.
The code using this sensor has been integrated into the project. Uncomment the line #define PIR in the OpenCat.ino, as shown in the figure below, and use the Arduino IDE to upload the sketch to the robot main board, which can reproduce the example function of integrating the robot action.
You can use the within the Petoi Desktop App. Please select the correct Product type, Borard version, and Serial port. The mode should be Standard, so press the Upgrade the Firmware button. for example, Bittle, BiBoard_V0_2, COM5 as follows:
After uploading, and use the serial command "XI" to switch to using the PIR motion sensor mode.
You can use to (OpenCatEsp32.ino). Use the latest OpenCatESP32 code to finish the setup. For example, to modify the code for Bittle as shown below:
After uploading, open the and use the serial command "XI" to switch to using the PIR motion sensor mode.
This demo sketch implements real-time printing of sensor detection results in the - when anyone moves within its detection range, print 1; otherwise, print 0.
