Development

Program Download

• Download and unzip the program File:Sensor-PIR Test.zip

Programming

• Follow the Software Getting Started Guide.
• Select the Board, Processor and Port.
• Click [File]->[Open], browse to the project program address, and click "Sensor-PIR Test.ino" to open the program.
• After confirming all these items are correct, click "→" to download the program to the development board.

Hardware Setup

• Referring to the following diagram, connect the Sensor-PIR to the digital pin D6 of Microduino-Sensorhub.

Result

• After download, open the serial monitor.
• The static sensor signal is LOW. After detect the IR emitted by living things within measurement range, it changes into HIGH.

Application

• Intrusion alarm
• Non-contact infrared automatic switch
