ESP32 Arduino Tutorial: PIR motion sensor DFRobot

In this esp32 tutorial we will check how to use a PIR sensor to 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, to trigger an alarm or to turn on the lights, amongst many other possible application scenarios. PIR stands ...

Motion detection with ESP32 cam only (Arduino version)

20200105· PIR sensors gets triggered by infrared light. Infrared light gets emitted by hot bodies (like people and animals). But motion in a video stream can happen for a variety of reasons, not necessarily due to hot bodies, for example if you want to monitor a street for cars passing by. A PIR sensor can''t do this: video motion detection can. ESP32 cam ...

ESP32 Arduino Tutorial: Alarm with PIR motion sensor and ...

As can be seen in figure 1, one of the ESP32 GPIOs will be connected to the PIR sensor, since this device outputs a voltage of V when motion is detected. Note that although our circuit is operating at V, a value of V is still interpreted as a HIGH logical level by the ESP32, which means we can interact with the sensor considering it outputs a digital signal.

PIR motion sensor and Buzzer with ESP32

The operation of the PIR sensor is very simple. The sensor has a signal pin which outputs a voltage of V when motion is detected. Here both the buzzer and sensor operating at value of V considered as a HIGH logical level by the ESP32. Which means that we can interact with the sensor considering it outputs a digital signal.

ESP32 Arduino: PIR motion sensor techtutorialsx

20210730· This PIR motion sensor will be interfaced with the ESP32 board and a 5mm LED. Through interrupts and timers of ESP32, the LED will be controlled. Whenever motion will be detected, an interrupt will be triggered, a timer will be activated and the LED will turn ON for a set number of seconds. After the timer stops, the LED will turn OFF. In other words, this tutorial is a motion detection ...

ESP32 with PIR Motion Sensor using Interrupts and Timers

20200413· This tutorial shows how to detect motion with the ESP32 using a PIR motion sensor. In this example, when motion is detected (an interrupt is triggered), the ESP32 starts a timer and turns an LED on for a predefined number of seconds. When the timer finishes counting down, the LED is automatically turned off. With this example we’ll also explore two important concepts: interrupts and …
