Sensors and Detectors

Today parking is big problem everywhere. Parking become easy with this Arduino idea. So we made small Arduino Based Smart Car Parking Sensor Circuit. This system detects car and display free or busy slot automatic. Arduino brain tell LCD which slot free. No confusion, no searching, just smart slot information. Simple circuit with smart working […]

Air pressure is around us all time, but we cannot see it. With HX710B sensor and Arduino, we can measure it easily. This project for Arduino Air Pressure Circuit with Sensor HX710B show pressure value on LCD in real time. Just connect wires, upload code and see pressure on screen. Circuit is easy, code is […]

This project for Rain Detector Circuit using Arduino shows how to detect rain. Rain sensor plate feels water drops. Module gives analog and digital signal. Arduino reads signal. LED glows when rain starts. This is low cost and easy project for beginners. Arduino Coding: Code Explanation: Circuit Working: Parts List: Component Quantity Resistor 220Ω 1/4 […]

Railway accidents happen because obstacles come on railway track. Many trains cannot stop fast. This project uses Arduino Uno, ultrasonic sensor, relay and motor or servo to give warning or stop mechanism. The system checks distance. If object comes close, relay activates and motor moves barrier or alarm system. This helps to avoid accidents in […]

This project show how to make a simple Arduino Based Pulse Monitoring Circuit. It uses Arduino Nano, pulse sensor, OLED display, buzzer, an LED. The system reads heartbeat from finger sensor. Then Arduino calculate pulse per minute. OLED show result. LED and buzzer give alert when pulse go high or low. Circuit is simple and […]
