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 ...

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 ...

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.

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 ...

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

If you're savvy and want to do a bit more home monitoring, these interesting sensor ideas might be worth trying.

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 ...

Random numbers are very important to us in this computer age, being used for all sorts of security and cryptographic tasks. [Theory to Thing] recently built a device to generate random numbers ...

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 ...

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, ...

This code example demonstrates a CAPSENSE™-based proximity sensing design to control the brightness of an onboard LED. It helps to learn how to design a proximity sensor using a PSoC™ 4 device, and ...
