Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

A team of engineers at Rice University has developed a tiny new sensor that could dramatically improve the safety of self-driving cars on public roads. This is a compact, low-power millimeter-wave ...

In recent years, integrated platforms equipped with microcontrollers (with Arduino probably being the best-known brand) have been gaining popularity.

The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...

A dark line across the nose can happen from rubbing it a lot due to allergies. The line may go away on its own, but treatments like creams or laser therapy can help if it doesn't. You can prevent the ...

Abstract: This paper proposes a phase delay line sensor for water quality monitoring based on spherical conformal reflec-tarray antenna (RA) operating at a central frequency of 5.8 GHz. The sensor is ...

Distribution line monitoring eliminates structural search delay in feeder restoration. When a breaker trips without downstream visibility, patrol distance dictates outage duration. Each mile walked ...

Abstract: This paper introduces a novel method for precise object grasping point estimation using a palm-type line laser sensor. Active stereo sensors have difficulty in accurately determining object ...

Line sensors for utilities provide near real-time fault detection, waveform capture, and feeder visibility, reducing patrol time, improving outage isolation, and strengthening ADMS model accuracy ...
