Introduction to Ultrasonic Radar: The functionality of Arduino is truly powerful, allowing for the creation of interesting projects using various sensors. Today, we will develop an ultrasonic radar using the Arduino board and ultrasonic sensor, capable of detecting distances up to 40CM. When there are obstacles, the scanning interface will display red and show the … Read more
PIR Motion Sensor The PIR motion sensor, also known as a human infrared sensor, is widely used in fields such as anti-theft alarms, visitor notifications, and non-contact switches. Piezoelectric ceramic dielectrics can maintain a polarized state after polarization, known as spontaneous polarization. Spontaneous polarization decreases as temperature increases and drops to zero at the Curie … Read more
The proximity sensor is used to detect the presence of nearby objects. For example, the LJ12A3-4-Z/BX inductive proximity sensor is a compact, low-power, user-friendly, and stable proximity switch sensor used to detect the presence of metal objects. The LJ12A3-4-Z/BX has three pins, two for connecting to a 6-36V power supply, and the third is a … Read more
I was thinking, when everyone is talking about smart hardware, perhaps the once popular 3B advertising principles: beauties, beasts, and babies are still applicable. During this year’s CES, we led everyone to take stock of smart hardware products related to women. Next, the founder of the company was invited to report on the London Toy … Read more
Today, a letter arrived from Stanford University, containing a card with a single sentence:“I am an engineer. The way I serve humanity is by making dreams come true.” The origin of this quote is unknown, but coincidentally, someone we recently interviewed said almost the same thing. Perhaps this is a common “belief” among engineers. The … Read more
OpenBot AI Robot Another AI? It seems that now anyone who can walk a few steps on the ground dares to call themselves AI. People are starting to feel aesthetic fatigue. Well, let’s first take a look at the introduction video of the OpenBot robot presented in this article. From the video, we see that … Read more
