Consumer Reports' tests reveal the best AC controllers to remotely control window ACs, portable ACs, heat pumps, and ...

Toaster oven reflow projects are such a done deal that there should be nothing new in one here in 2025. Take a toaster oven, ...

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual intervention. It is built around an Arduino Uno, which is programmed to ...

She is a member of Project Sunset, which is a network of tobacco control researchers and advocates who support phasing out the general retailing of commercial tobacco products. Hollie Bendotti ...

We are going to use this technique to build a our bidirectional visitor counter using arduino and ir sensor. By placing two IR sensors one after another in series as shown in the above image at a ...

Seeed Studio’s XIAO 6-Channel Wi-Fi 5V DC Relay is a compact ESP32 ... Additionally, it supports Wi-Fi-based remote control and automation without additional configuration. On top of that, you have ...

Herein, a dual-channel nondispersive infrared (NDIR) ETO sensor based on a direct optical path with explosion-proof performance was designed. Given ETO’s flammability, the sensor was employed an ...

Abstract: Underwater acoustic sensor networks (UASNs), which are formed by a number ... Typically, the localization, communication, and control are the fundamental services for the applications of ...

The SparkFun Spectral UV Sensor - AS7331 (SEN-23517) and SEN-23518 features the AS7331 UV sensor from ams OSRAM©. It measures UV radiation on three channels: UVA (320-400nm), UVB (280-320nm), and UVC ...

2.56 MHz. Note: higher speeds and longer wires need smaller pull up resistors. Some timings in micros for INA.getMode() on an Arduino UNO. This is just one readRegister call, similar to most functions ...

An Arduino replaced the OEM controller, and wired up to temperature sensors and an IR sensor that watches for ice buildup on the lower part of the coil, the heat pump is now much better behaved.
