In this project we use ESP8266 in its NodeMCU form factor as a home security device which with the help of PIR sensor senses the movement of intruder and sends and email and mobile notification to the owner along with the time. What is PIR Sensor? 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 ...
ESP8266 and PIR example in Micropython. 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.
And on the subscriber side, and the full code to upload to ESP8266 on GitHub: define mqtt_port 1883 define subscribe_topic "sensor/door/pir" define SENSORNAME "One1W" In the video, you can see that the HIGH status of PIR retained about 56 seconds after the last motion while the subscriber (LEDs) is ON for 12 seconds.
· esp8266PIR. PIR Sensor for ESP8266. Language: micropython. Overview: This code will connect to a MQTT server and listen to see if the sensor should be active, if it is the PIR sensor is enabled and triggers when motion detected. If the sensor is not set to enabled it enters deep sleep for 30 minutes before restarting and checking again.
· 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 ...

Infrared sensors are designed to detect infrared waves emitted by objects and consist of two parts: Pyroelectric Sensor and Fresnel lens. The pyroelectric door is made of two rectangles in its structure that allow infrared waves to enter and behind it are two infrared sensor electrodes. The …
· 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.
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 issue is the PIR sensor that comes with ESP8266 can work with as well as 5V. By default, the wiring is connected to the 5V which may work fine for the Arduino device but not for ESP8266. I just removed the red cable (power cable) from the connector and connected to the other side where you can see H. That side also there are 3 pins.
· Security Sensor Tutorial Using PIR Sensor and ESP8266. This tutorial will walk you through the steps of using an ESP2866 and a PIR Sensor to detect motion, and send you notifications using a Wia. Beginner Full instructions provided 2 hours 3,010. Ad.
Code to Note. PIR sensor has three terminals V cc, OUT and GND. Connect the sensor as follows − . Connect the plus;V cc to plus;5v on Arduino board. Connect OUT to digital pin 2 on Arduino board. Connect GND with GND on Arduino. You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor board. Once the sensor detects any motion ...
· 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.
