· ESP8266 – PIR Motion sensor detection. First, The Question: What is a PIR sensor? A PIR module is basically made of a pyroelectric sensor (see it below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the ...
IoT Motion sensor Working Theory. We have connected the PIR motion sensor to one of the GPIO pins of the NodeMCU ESP 8266. Whenever the PIR detects motion then the output sates of the PIR sensor will change which will be detected by the controller. We have programmed the NodeMCU to make an HTTP GET request to our IFTTT webhooks applet.

The PIR Sensor acts as an source for the external interrupt. That means we connect the output of PIR sensor with the GPIO pin of ESP32 and ESP8266. Furthermore, we attach the rising edge triggered interrupt to this GPIO pin. That means this GPIO pin will trigger the interrupt whenever it will sense rising edge on its input.
· Node MCU ESP8266 interface with PIR Motion Sensor with code The project uses PIR sensor to sense the motion of human and turns ON an LED to detect the motion. When movement of human will be detected by the PIR sensor. PIR Sensor provides a triggering pulse to NODE MCU GPIO Pin 5 which is data D1 0n board.
· ESP8266 NodeMCU ; Micro-USB to USB cable; PIR Motion Sensor (HC-SR501); Male to male jumper wires; 1 Breadboard; Note: You do not need to have a NodeMCU board nor an ESP8266 to follow this tutorial. I am using this board because it is very famous and also because, i will post future tutorials using wifi communications.
In this example we look at a PIR example in Micropython for an ESP8266. Once again we use uPyCraft and again we use Wemos shields. Lets remind ourselves about the PIR. A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. A PIR-based motion detector is ...
· This tutorial demonstrates how to create a security sensor, using a PIR sensor, ESP8266, and the Arduino IDE, to indicate both high and low movement.
Using your female to female jumper wires, make the following connections between the PIR sensor and the ESP8266. Use the illustration to help you. Setting up your development environment Now that the sensor is connected, let's get the development environment set up for the ESP8266:
· With the help of an infrared sensor the Arduino, ESP8266 and ESP32 microcontroller is able to receive information from an infrared remote and take action based on the button you pushed on the infrared remote. Therefore the sensor scans specific frequency ranges, defined by standards, and convert these signals to the output pins of the sensor.
· The wiring between the HC-SR501 PIR Motion Sensor and the ESP8266 or ESP32 has a major difference compared to the wiring for the Arduino, because we do not use the standard pins for the power supply, but the jumper wire 1 that you saw in the previous chapter. The digital output of the HC-SR501 is received from digital pin D7 of the ESP8266 and from pin 4 of the ESP32. The following …
In this tutorial, we'll go through all the steps required to connect a HC-SR501 PIR motion sensor to an ESP8266 WiFi development board. About the sensor. The HC-SR501 module uses a passive infrared sensor and an integrated circuit (IC) to detect motion. It features adjustable sensitivity that allows for a motion detection range from 3 meters to 7 meters. The module also includes time delay ...

· ESP8266 12E from NodeMCU PIR Motion Sensor - HC-SR501 I updated the firmware already with Arduino IDE and setup ESP8266 lib on Arduino IDE. I tested ESP successfully with blink sketch and wrote another sketch to turn the LED on or off from the web page by making ESP an access point. My issue is, making it work with PIR sensor, as ESP works with and PIR works with 5v. I …
· The solution I found to this problem is use a 10k resistor between the PIR sensor output and the input pin of the ESP8266. I tried all of the suggestions above (caps, switching off the wifi etc) but only the resistor worked.

Connecting PIR sensors to a NodeMCU is really simple. The PIR acts as a digital output so all you need to do is operate the pin to flip high (detected) or low (not detected). Check out the images for more details. Most PIR modules have a 3-pin connection at the side or bottom. The pinout may vary between modules so check the pinout carefully ...
