Many buildings and sites tied to national security rely on cameras and sensor networks to detect people and other objects ...

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 ...

Lifestyle-related type 2 diabetes and associated obesity (diabesity) affect >2.5 billion people worldwide and impose nearly ...

Sofa, so good.

Since the ESP32 and the display are integrated into the board, there's very little additional wiring involved. The mmWave sensor does need to be connected, and to make room inside the enclosure, the ...

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 ...

Smart home gear keeps consolidating around the Matter smart home standard, and a lot of the newest devices run on Thread, a low-power mesh network that sits alongside your Wi-Fi instead of on it. Most ...

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 the previous chapter, we turned the knob of a variable resistor and observed how the analog input value changed. This time, we will use a **light sensor (CdS cell)**, which changes its resistance ...

After a 7-year corporate stint, Tanveer found his love for writing and tech too much to resist. An MBA in Marketing and the owner of a PC building business, he writes on PC hardware, technology, and ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
