Having an enclosed 3D printer can make a huge difference when printing certain filaments that are prone to warping. It’s easy enough to build an enclosure to stick your own printer in, but ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

I've completely swapped my home over to LED lights, and for the most part, I love it. The energy savings are real, and I'm a sucker for all the smart color changing tes. But my biggest grievance is ...

Abstract: Pyroelectric infrared (PIR) sensors are much promising for device-free localization (DFL) due to their advantages of lower cost, low power consumption, and privacy protection. Most PIR-based ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: An important issue faced while employing Pyroelectric InfraRed (PIR) sensors in an outdoor Wireless Sensor Network (WSN) deployment for intrusion detection, is that the output of the PIR ...

Is a human micro-motion sensor that can detect and recognize moving, standing, and stationary human body. The code in this library is based heavily off this LD2410, Waveshare and RD-03 documentations.

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 ...

The SHT3x family of sensors should work up to 1 MHz I2C. This library should also work for SHT30 and SHT35 but these are not tested yet. Sometimes you need to control more devices than possible with ...
