The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for ...

In today's lecture, we will design a project in Proteus, where we will Interface Gas Sensor with Arduino. I will provide the complete code and simulation. Gas sensors are widely used in fire alarms, ...

STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm passive IR sensor. This provides more accurate results as well as information about the distance rather than just a basic ...

This research is aimed to explore the efficacy and comparison of low-cost light sensor measurements for agricultural applications. For this reason, TSL2561, BH1750, and TEMT6000, low-cost light ...

A homing sensor is a device used in certain machines to detect a fixed reference point, allowing the machine to determine its exact starting position. When powered on, the machine moves until it ...

The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

A light source and photosensor combine for effective, reliable, non-contact proximity detection of nearby objects. Part 1 of this article looked at the principles and three basic approaches to optical ...

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 ...
