This project demonstrates the creation of an Arduino-based non-invasive glucometer. The glucose level is estimated using a trained polynomial regression model based on heart rate (BPM) and oxygen ...

Moisture Sensor 1: A0 Moisture Sensor 2: A1 Moisture Sensor 3: A2 (if applicable) Moisture Sensor 4: A3 (if applicable) Connect the VCC and GND pins of each moisture sensor to the corresponding power ...

Telemetric devices for vehicles, better known as black boxes, cracked the consumer scene 25 years ago with the premiere of OnStar. These days, you can get one for free from your insurance company if ...

Abstract: In this paper, we present the TacShade: a newly designed 3D-printed soft optical tactile sensor. The sensor is developed for shape reconstruction under the inspiration of sketch drawing that ...

Abstract: This design utilizes a light-dependent resistor (LDR) and an STM32 microcontroller to work together for real-time solar tracking, optimizing solar energy capture. Combined with the 28BYJ-48 ...

When someone hacks together a digital camera with a Raspberry Pi, the limiting factor for serious photography is usually the sensor. No offense to the fine folks at the foundation, but even the “HQ” ...

Scientists have developed a new kind of wearable sensor that can detect signs of eye disease—without drawing blood or using expensive lab equipment. Instead, it’s a soft, non-invasive patch placed ...

The best outdoor solar lights are an efficient and sustainable way to brighten a space, helping you save on electricity costs and avoid the hassle of outlet plugs and battery replacements. The most ...

Adaptive Brightness is a helpful feature on old and new Android devices. It’s a feature that automatically adjusts the brightness levels of your display based on the environmental lighting. Moreover, ...
