As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

The circuit Diagram for arduino motion detector project by interfacing Arduino with PIR module and blinking an LED/Buzzer is shown in the below image. We have powered the PIR sensor using he 5V Rail ...

Once the system was armed, a red LED would light up to indicate its armed status. If motion was detected while in this state, a buzzer would activate and would not be disabled until the user entered ...

// Bu projedeki temel hedef arduino kullanarak duman sensörünün çalışma rensibini daha iyi kavrayabilmektir. Duman sensörleri temelde içine giren duman (yangın dumanı, sigara dumanı, su buharı gibi) ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security purposes.
