This project demonstrates how to use an IR infrared sensor module with an Arduino Uno to detect the presence of objects. The IR sensor emits infrared radiation and detects reflected radiation from ...

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

An infrared sensor is an electronic module that is used to detect the certain physical appearance of its surroundings by either emitting and/or detecting infrared radiation. IR sensors can also sense ...

This project involves creating a flame detection system using an Arduino UNO and a flame sensor. The system detects the presence of a flame and provides visual and serial output alerts. It utilizes ...

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 ...

Abstract: An infrared sensor based prototype of self-adaptive traffic signal control system has been developed in this paper. An autonomous traffic signal system can be an effective measure to ...
