In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

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 ...

BMV080 is a low-power, low-cost PM1, PM2.5, and PM10 sensor module with I2C and SPI interfaces that sells for just $29.90.

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with ...

Abstract: A highly sensitive and stable temperature sensor based on a diamond-Ga2O3 Schottky-p-n diode is demonstrated in this work. The forward current exhibits a pronounced temperature dependence, ...

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 ...

Abstract: Global warming and the associated increase in heatwaves have made the prevention of heat-related illnesses such as heatstroke a critical global challenge. Monitoring physiological indicators ...

Easy-to-use interface for configuring and reading radar data. Supports both single and multi-target detection modes. Works with Arduino-compatible board that has a separate hardware UART.
