This Arduino-based burglar detection alarm uses a PIR sensor to detect motion. When movement is sensed, an LED lights up and a piezo buzzer sounds an alert. Ideal for security applications, this sy ...

LED Light: An LED emits light whenever current passes through it. For this project, whenever the PIR sensor detects warmth it will send current to the LED and it will turn on briefly before turning ...

RCWL-0516 Doppler RADAR Motion Sensor The RCWL-0516 Doppler RADAR Motion Sensor module has been designed as an alternative to the common PIR motion sensors that are widely used by hobbyists and in ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...

RCWL 0516 Module The RCWL-0516 Microwave Radar Sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Like the PIR Sensor ...
