ESP32 with PIR Motion Sensor using Interrupts and Timers ...

06/02/2020· 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. More info. ESP32 newsline pir sensor.

ESP32-CAM PIR Motion Detector with Photo Capture | Random ...

10/12/2019· Double check the connections of the PIR motion sensor. To make sure the ESP32-CAM is working properly, you can try attaching a pushbutton instead of the PIR sensor and see if it works as expected. Also, check with a multimeter if the PIR motion sensor is working as expected. Regards, Sara. Reply. Enzo . March 23, 2020 at 11:35 am Thank you. Reply. Jeff Young. August 23, 2019 at 8:51 am …

The connection diagram of this PIR sensor to the ESP32 is quite simple. Three pins need to be connected: PIR VCC to ESP32 dev board 5V; PIR GND to ESP32 GDN; PIR DATA to ESP32 GPIO through a 1K Resistor (D2 in this tutorial). Note: The ESP32 GPIOs require 3V3 signals (not 5V tolerent). For quick hack, you can only add a serial resistor of 1K between the PIR DATA pin and the ESP32 …
