This simple arduino alarm is an easy build that requires making a motion-sensing alarm using a PIR (passive infrared) sensor and an Arduino microcontroller.
A very design rain sensor
Use NE566 as a function generator or Voltage controlled oscillator or VCO circuit. We can control output frequency by adjusting amplitude of Input voltage.
Send notifications to your Telegram account when the ESP8266 NodeMCU detects motion. You'll receive the notifications from anywhere and program the ESP with Arduino IDE.
Make an Simple Motion Sensor Theft Alarm! (PIR) : This is an Continuation of my How to Simple Series of Motion Sensor Things. All Previous Instructables in Simple Series were Featured. And Another Step in Theft Protection with this Ultra Simple Project Measuring only 4cm Length. with a Totally Ear …
Suitable for kitchen, hallway, guest room, living room, bedroom, etc. Rotation: 140°. Notes: The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.

What a Technician needs to know about MAP (Manifold Absolute Pressure) sensors when diagnosing related faults and testing operation on the vehicle.
The PIR (Passive Infra-Red) Sensor is a device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin.

A remote sensor automatically lights up dark sidewalks and yards. And it'll operate any light fixture. In this story, we'll show you how to instal
This is a simulation example from Compumag TEAM Workshop Problem 30. To simulate the motion we will attenuate the AC problem frequency.
Humidity Indicator and Controller - Presented here is a simple humidity indicator and controller. In industries such as textile, the change in moisture content has a direct impact on the properties of fabric, such as tensile strength, elasticity, fibre diameter and friction.
A dumpy level, also known as an automatic level or builder's level, is a tool designed to find the height of land masses. Though these devices may look intimidating or confusing, dumpy levels are fairly easy to use once you know how to set...
