接下来,我们有我们的设置功能,在这个功能中,我们将 pir 传感器引脚和 led 引脚的引脚状态设置为输出,我们还启用串行监视器以打印调试语句。 void setup() { pinMode(ledPin, OUTPUT); // declare LED as output pinMode(inputPin, INPUT); // declare sensor as input Serial.begin(9600); } 接下来,我们...

In thisesp32 tutorialwe will check how to use aPIR sensorto detect motion, using an ESP32 and the Arduino core. Since a PIR sensor allows to detect motion, it means that we can use it to know when someone enters and leaves a certain area. That information can be useful, for example,...

1. HC-SR505 PIR Motion Sensor Module - it detects only motion and I can't setup a distance of detection for it so it triggered not only when cat is moving but anybody in a range. 2. A few proximity sensors - the main problem that they has small angle from 1° to 45° but the...
We can use external interrupt pins in various situations ranging from simple notification when a PIR sensor detects the motion of somebody in a room. And up to doing some measurement stuff and calculations like measuring the frequency of a digital sensor such as an “Optical Encoder” to measure...
