Buy Mini Body Sensing Detector Mini PIR Motion Sensor Module – DC 3.3V-15V Body Sensing For DIY Projects Esp32 Sensors ...

係網上祗係搵到類似用E塊板既link, 睇哂D資料就知道塊板係可以探測紅外熱能活動既簡單感應器,所以信號輸出只有高/低兩個電 ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

To detect motion using a PIR sensor connected to an Arduino and trigger an LED (using the built-in LED) when motion is sensed. Passive Infrared (PIR) sensors are electronic devices that detect motion ...

Once motion is detected, the sensor sends a HIGH signal to the microcontroller, which can be used to trigger a response such as turning on an LED or activating an alarm. In this experiment, the PIR ...
