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 ...

Researchers developed a fingertip-sized, humidity-tolerant hydrogen sensor using platinum nanoparticles that catalyze reactions, thin a water film, change color, and trigger alarms. (Nanowerk News) ...

Hydrogen plays an important role in society’s energy transition. For the technology to be used on a broad scale, effective hydrogen sensors are required to prevent the formation of flammable ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Arduino library for the ENS21x temperature & humidity sensor family with I2C interface from ScioSense. The ENS21x is a family of high-performance digital temperature and humidity sensors produced by ...

(Nanowerk Spotlight) Each exhaled breath carries distinct signatures of human activity - quick and shallow during exercise, deep and regular in sleep, irregular while speaking. These breathing ...

Abstract: Here we report development of a zinc oxide (ZnO) nanorods based humidity sensor prototype using Arduino Uno microcontroller platform. A commercial humidity sensor (DHT11) was also connected ...

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over ...
