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 MAX471 is an older current sensor which can handle up to 50 Watt, with a maximum of 25 Volts or a current of 3 Amperes. It is officially not supported any more however there are still many for ...

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 ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor-assisted in situ polymerization and freeze-synergistic assembly. These ultralight, porous pressure ...

Featuring DC to 5-MHz bandwidth, Allegro MicroSystems' galvanically isolated, high-accuracy magnetic current-sensor IC with zero current reference (ACS37030), and overcurrent fault with internal pull ...

The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...
