Why pay a premium for smart devices when an ESP32 and some cheap sensors can do everything for a fraction of the price?

Scientists have developed a tiny temperature sensor that harvests energy from magnetic fields near electrical wiring.

Build a DIY ESP32 LoRaWAN sensor node to track garden temperature and humidity from up to 600 meters away. Includes PCB ...

His new Marble Scroller is a huge 3D-printed wheel that writes text in black and white marbles using a 7x5 pixel font, lets ...

Researchers have developed a groundbreaking 3D invisibility cloak that can hide complex objects from infrared cameras while protecting them from extreme heat and cold. Instead of blocking heat, the ...

A Class 10 student from Hyderabad has found a tech-powered way to make his mother’s birthday special by building a miniature ...

A teenager from Hyderabad built a miniature ropeway to deliver a birthday card to his mother. The Arduino-powered surprise ...

Measuring electric currents is an essential element of many electrical systems, but doing so in a way that is as nonintrusive as possible is not an easy problem to solve. Due to this we got a wide ...

The air around us rarely announces itself. Exhaust from a busy road, dust from a building site, smoke from burning leaves, fumes from a kitchen, or a closed ...

Let's use Arduino to make a light that turns on automatically only when someone approaches and turns off after a while.This time, we will use a PIR motion sensor that detects changes in infrared rays ...

In my early ESP32 tinkering days, I’d only use the microcontroller to test with LEDs, resistors, and other circuitry components. In fact, writing simple C++ programs to perform basic tasks on the ...

Lockheed Martin (LMT) said Wednesday that its Legion infrared sensor system successfully exchanged targeting information between two F-16 fighter jets during flight tests in Arizona, demonstrating a ...
