in this instructable I'm going to show you how to make a wireless motion alarm system, this device consists of a transmitter and a receiver. So essentially it is a pretty simple and basic wireless motion alarm system with light indication.

Learn: how HC-SR501 motion sensor works, how to connect motion sensor to Arduino, how to code for motion sensor, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are …

It includes two Arduino Nano microcontrollers, each interfaced with an NRF24L01 wireless transceiver module. Additionally, the circuit incorporates an HC-SR501 PIR motion sensor to detect motion and a buzzer for audible alerts. A servo motor is also part of the system, which can be controlled based on signals from the microcontroller.

1) Simple motion sensor with one arduino and a led will flash when motion is detected. 2) Using a second arduino , a transmitter and a receiver I made the system wireless. 3) Using an Arduino GSM shield I will be calling myself every time motion is detected.

As you can see we will be using a classic movement 5 volts sensor attached to an Arduino Nano or Uno. At the same time, Arduino will be attached to a NodeMCU to send signals to the wifi network. Let's see how to connect them. Not too complex, the Arduino will exchange information with the NodeMCU through their own D3 and D4 pins.

Sep 21, 2020 · Looking for feedback on creating a small wireless Motion detection system that can send digital alert messages. The simplest way to describe what I need is equivalent to a typical wireless driveway alert device.

Mar 10, 2025 · When paired with an Arduino, a motion sensor can be programmed to respond intelligently, creating an efficient and responsive system. This guide explains how motion sensors work, how to connect them to an Arduino, and how to write the code needed to make them function properly. The most common motion sensor is the Passive Infrared (PIR) sensor.

This document provides a detailed overview of a circuit that includes an Arduino Nano as the central microcontroller, interfaced with an NRF24L01 wireless transceiver module, an MPU-6050 accelerometer/gyroscope, an 18650 battery in a holder for power supply, a red two-pin LED, and a …

Welcome! This tutorial will guide you through using an Arduino UNO R4 with a motion sensor and a servo motor. It’s clear and simple, ideal for beginners. The motion sensor detects movement, and the servo motor rotates to a specific angle. You can use this to control things like a gate, a camera, or a small robotic arm.

For wireless communication, the circuit employs an Nrf24l01 PA/LNA RF module. User inputs are captured through three tactile switch buttons. An Arduino UNO serves as the microcontroller to process data and control the circuit's behavior. The circuit also includes resistors and an electrolytic capacitor for stability and noise reduction.
