In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

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 Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...

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

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

NEW projects in hilly areas in Ampang Jaya, Selangor, will be required to instal Early Warning Systems (EWS) as part of their development conditions. Ampang Jaya Municipal Council (MPAJ) deputy ...

Nurses are the tireless heroes of healthcare, unsung and under-resourced. They believe in the work they do and work every day to do more with less. Thankfully, new technologies and workforce ...

There are some key clinical and financial use cases already showing their worth – but while innovation around artificial intelligence is happening rapidly, there's risk in moving too quickly, one ...
