PIR传感器有三个端子--Vcc,OUT和GND。 按如下方式连接传感器 - 在Arduino板上连接+ Vcc至+ 5v。 将OUT连接到Arduino板上的数字引脚2。 在Arduino上连接GND和GND。 您可以通过位于传感器板底部的两个可变电阻来调整传感器灵敏度和延迟时间。 一旦传感器检测到任何动作,Arduino将通过串行端口发送消息,表示检测到动作。
I have used pin 5 as output from Arduino to the buzzer and light. There running process and stop the process of Arduino pin 5 are controlled by PIR sensor. The source code of Arduino, void setup() { pinMode(4, INPUT); pinMode(5, OUTPUT); } void loop() { int data = ...
Here’s the Arduino Code for this example. It’s quite simple. We just need to define the PIR Sensor pin as input and the relay pin as output. Using the digitalRead() function we will read the output of the sensor and if its high or if an object is detected it will activate the r...

Learn how to use the BME680 environmental sensor module with Arduino to read gas, temperature, humidity and pressure. Build the circuit and write a sketch example.
Here is how to hook it up: Get theFritzingsource for the above imagehere. Once you have it hooked up, head on over to theArduino Playgroundand get thesketchto make it work. I added a buzzer and it alerts me when anything (including the cat) sneaks up on me....
For a PIR tutorial with CircuitPython and Arduino code examples and project ideas, check out our PIR sensor tutorial page! The BS sensor window is 4mm x 3mm. We also carry the BL412 PIR sensor which has a larger sensing element (so it will be more sensitive) Play video: New Products ...
