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. ... to ~38kHz signal yielded by D9 of the ...

The Arduino Uno IR Sensor detects infrared (IR) radiation emitted by objects. It typically includes an IR transmitter and receiver pair, with the receiver detecting reflected IR light. This enables ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

In this project we are going to work on an innovative arduino project idea, where we can count the paper currency notes and calculate their amount, by sensing the paper currency using Color Sensor and ...

Arduino Sensor Kit Base is sold for $23 on Seeed Studioor the Arduino Store, where you’ll also find the $38.70 bundle kit with an Arduino UNO inside the package. Jean-Luc Aufranc (CNXSoft) Jean-Luc ...

So this inspired us to use GSM module for this project since the telecom network is widely spread within rural & urban area of the India. This system is used to monitor physical parameter like heart ...
