The Motion Sensor Pinout The HC-SR501 motion sensor has three pins: GND pin: This must be linked to GND (0V) VCC pin: This must be linked to VCC (5V) OUTPUT pin: This is an output pin. It will be LOW when no motion is detected and HIGH when motion is detected. This pin needs to be connected to an ESP8266's input pin. A Super Simple ESP8266 IOT Motion Sensor 31 Comments by: Tom Nardi July 19, 2018 It's really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For.

Hope you are doing fine. So today we will discuss the working of an esp8266 motion sensor. Well, I hope you know what a PIR sensor is. If not then don't worry we will give you a brief introduction to it. ESP8266 - Motion Sensor - LED Strip. This tutorial instructs you on how to create a seamless lighting automation system using an ESP8266, an HC-SR501 motion sensor, and an LED strip. Tailored to trigger the LED strip upon detecting human presence, this versatile system is well-suited for a range of applications, including: 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/DC converter. Prerequisites

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. This tutorial instructs you how to use ESP8266 and motion sensor to control servo motor. In detail: When motion is detected, ESP8266 rotates servo motor to 90 degree. When motion is not detected, ESP8266 rotates servo motor back to 0 degree. This can be applied in an automation process that triggers actions upon detecting human presence. The ESP8266 is a versatile Wi-Fi-enabled microcontroller that can be used for a wide range of IoT and automation projects. In this comprehensive guide, we will explore how to use an ESP8266 with a Passive Infrared (PIR) motion sensor to create your own motion-activated projects. Breadboard ESP8266 - NodeMCU PIR Sensor 3 Jump Wires Wiring To wire everything together, you should follow this schematic: The PIR sensor typically has 3 leads attached: VCC, OUT and GND. Connect the VCC PIR sensor pin to a 3v3 pin on the NodeMCU. Connect the GND PIR sensor pin to a GND pin on the NodeMCU.

Part 1 is here. PIR (Passive infrared sensor) or motion sensor is as its name implied detects a heat source that moves. Human, dog, cat moving across the front of the sensor triggers a HIGH signal. Here is a very nice diagram from Adafruit about the PIR sensor. PIR sensor is lost cost, and the response time is instant. This tutorial instructs you on how to use ESP8266, an HC-SR501 motion sensor, and an MP3 player to trigger the playback of a recorded audio file upon detecting motion. This project is versatile and can be tailored for applications like automatically delivering recorded audio instructions or warnings whenever a human presence is detected.
If you want to try a PIR motion sensor instead, read this tutorial: ESP32 and ESP8266 with PIR Motion Sensor using MicroPython. We have tutorials for more than different 20 sensors and modules with the ESP32 and ESP8266. Check out the following link: ESP32: 25 Free Guides for Sensors and Modules; ESP8266 NodeMCU: 20 Free Guides for Sensors and. HC-SR501 PIR Motion Sensor for Arduino, ESP8266 and ESP32 The HC-SR501 PIR Motion Sensor is an infrared sensor that is able to detect motions. In this tutorial, I show you how the functionality of the HC-SR501 with the help of the schematic of the PCB.

Now use an FTDI or an Arduino as a USB to TTL converter to upload the code to your ESP8266-01 device. Once the circuit is connected, turn it on. When the PIR sensor calibration is complete, the LED present on the board will turn OFF after 30 seconds. Now, whenever motion is detected, the LED will glow, and a push notification with the message. The PIR Motion Sensor is a passive infrared sensor, which applies to projects that need to detect human or particle movement in a certain range. Since it is powerful and low-cost, it is widely accepted for open-source projects related to Arduino, raspberry pi, etc. This can teach beginners about PIR sensor.
