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.
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 ...

The ESP8266 is connected to a PIR motion sensor. When the sensor detects motion, the ESP8266 sends a warning message to your telegram account. You’ll be notified in your telegram account whenever motion is detected. This is a simple project, but shows how you can use Telegram in your IoT and Home Automation projects. The idea is to apply the concepts learned in your own projects. Introducing ...

· esp8266-PIR. 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. Purpose: Designed to be used in conjunction with Home ...
· 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.
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 ...
· The ESP8266 module has the deep sleep mode which allows to put it in hibernation to save the battery. You can wake up the module at regular intervals to make measurements and publish them on a server. The RESET pin (RST) is also used to wake the ESP8266. For example, the rising edge (the signal) of a motion detector (PIR) can be used. In this tutorial we will see the adaptations to the …
Roland Pelayo ESP8266 Tutorial 2 Comments 2,782 Views A Passive Infrared (PIR) sensor is a popular sensor for detecting the presence of a person. This is a type of proximity sensor although you may also call it a motion sensor. This tutorial aims to guide you in using a PIR sensor with your NodeMCU ESP8266 …
· Now lets Interface PIR sensor with ESP8266-01 Module. You can also use the devices like NodeMCU development board for this tutorial. In our case, we use the ESP8266-01 module. Actually, the PIR sensor is powered by 5V, but if we look at the circuit diagram, you will see that V is used inside.
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.
The ESP8266 consumes 100mA on average. The link to Adafruit has a detailed calculation of the time delay for the larger PIR version. For the larger version, the lowest (shortest) time delay setting relays HIGH status in 4-5 seconds after the last motion is detected. A half-way setting relays about 117- 120 seconds in HIGH status.
· ich verstehe deinen Aufbau nicht ganz: der PIR-Sensor weckt einen ESP8266 auf, hängt aber selbst an einem anderen Controller, oder? Er könnte ja kein Ausgangssignal generieren wenn er im Koma liegt. Ich suche nämlich selbst nach einer solchen Stromsparlösung (Akkubetrieb), bin aber noch am tüfteln wie ich das hinkriege. Ich muss den Raum nicht ständig überwachen, nur von Zeit zu Zeit ...
· 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.
Power supply for ESP8266 is max and PIR sensor is powered by 5V. If you check datasheet for PIR sensor you will see that internally is powered by (see regulator). Internal logic is so output. It can be directly connected to ESP8266 GPIO pin.

Hack a PIR Motion Sensor with an ESP8266. In this project we’ll modify a commercial motion sensor (powered with mains voltage) with an ESP8266 to log data whenever motion is detected. The data will be sent to Node-RED using MQTT communication protocol. The ESP8266 will be powered through the motion sensor phase out wire using the HLK-PM03 AC ...
An individual PIR sensor detects changes in the amount of infrared radiation impinging upon it, which varies depending on the temperature and surface characteristics of the objects in front of the sensor. When an object, such as a human, passes in front of the background, such as a wall, the temperature at that point in the sensor’s field of view will rise from room temperature to body ...
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.
