The term “smart sensors” might sound like a contradiction. After all, sensors are simple devices that detect and measure things like temperature or motion. So what makes a sensor “smart”?

 

What Makes a Sensor “Smart”?

Traditional sensors are straightforward. They detect physical conditions like heat or pressure and convert these into electrical signals. These signals are then shown on a screen or recorded. But this raw data needs more processing to be useful.

Smart sensors, on the other hand, add extra features. Here’s what sets them apart:

  • Data Processing: Smart sensors have built-in microprocessors. They can analyze data themselves and make basic decisions. For example, they can estimate how long it will take to heat a room or activate security cameras when detecting human movement.

  • Communication Capabilities: Unlike traditional sensors, smart sensors can send data wirelessly. They share processed data with other devices or central systems. This reduces network traffic and allows for remote monitoring and real-time decision-making.

  • Adaptability: Many smart sensors adjust themselves to maintain accuracy over time. They can calibrate automatically to handle changes in their environment.

Benefits of Smart Sensors

Smart sensors offer big advantages across different fields:

  • Reduced Data Traffic: By processing data on the device, smart sensors cut down on the amount of raw data sent over networks. This helps prevent network congestion.

  • Automated Actions: Smart sensors can trigger specific actions based on the data they collect. For instance, a smart irrigation system can automatically adjust water levels based on soil moisture.

  • Better Insights: Processed data from smart sensors gives a clearer view of the monitored environment. This helps in making better decisions, optimizing processes, and planning maintenance.

Why Are They Called “Smart”?

Smart sensors are crucial in the Internet of Things (IoT). They help create networks of devices that can collect, analyze, and share data in real-time. This technology is changing industries, from smart homes to factory automation.

So, the next time you hear “smart sensor,” remember it’s not just a fancy term. It highlights the sensor’s ability to process, communicate, and adapt. These small devices are driving a smarter, more efficient future.

Stablecoins might cut America’s debt payments?

When it comes to profit per employee, Tether is the most profitable company in the world. It may even be the most profitable business in the history of business. With $13.7 billion in profit last year and only around 165 employees, that’s over $83 million in profit per employee. It’s a staggering figure—blowing NVIDIA (NASDAQ:NVDA) and every other company out of the water. It’s literally off the charts. Has any business in history ever generated this much profit per employee? If there is, I’ve never heard of it. Tether gives anyone with a smartphone instant, global access to digital US dollars. With a market cap exceeding $162 billion and climbing, USDt (Tether) is the world’s largest stablecoin—and the fourth-largest cryptocurrency overall. Though calling it a "stablecoin"is something of a misnomer—government paper currencies, with their steadily eroding purchasing power, are anything but stable. In that sense, they’re less “stable” and more like “guaranteed-loss coins.” Tether claims to have over 400 million users globally—and is adding 30 million more every quarter. That’s explosive growth—reminiscent of Facebook (NASDAQ:META) at the height of its expansion. It’s no surprise that USDt is hugely popular in emerging markets and developing countries like Argentina, Venezuela, and Turkey—places where local currencies are rapidly losing value, and people turn to the US dollar as a relatively more stable store of value. USDt gives them access to US dollars they might not otherwise be able to get. Tether is like having a US dollar-based checking account—without needing a US bank. For billions of people, it’s simply a better way to hold and send dollars than the sluggish, outdated banking...

An Arms Dealer Joins Silicon Valley’s Military Boom

by | Jul 4, 2025 |

For years, Will Somerindyke sold weapons of war around the world: artillery shells to Ukraine, grenades to U.S.-backed rebels in Syria. With relationships with dozens of top military buyers, he quickly turned his company Regulus Global into one of America’s major international arms dealers. Now, as Silicon Valley investors swarm to back multi-billion dollar defense startups with increasing fervor, Somerindyke is looking to make the jump from munitions middleman to manufacturer. He’s been quietly working on Union, a new venture-backed startup he claims will modernize ammunition factories with autonomous robotics and precision machining. “I’ve been through a lot in 18 years in this space,” Somerindyke told Forbes. “If Union does its job correctly, we will be building millions of square feet of facilities with the ability to make a wide range of defense products.” Union, which Somerindyke leads as CEO, appears to have made a solid start. In April it secured a massive $50 million seed funding round led by Bravo Victor Venture Capital, or BVVC. Other investors include Silent Ventures, IronGate, and RKKVC, a Poland-based single-family office. It plans to open its first artillery shell factory in Texas next month. And it recently secured a contract to sell those shells, which, if fulfilled, could bring in up to $225 million, according to Somerindyke. But instead of approaching the problem with old-school manufacturing, Somerindyke and Musselman, who met more than a decade ago through a program for veterans, saw an opportunity to modernize weapons manufacturing, are using Silicon Valley software talent to implement autonomous systems. Since incorporating in October, Union has hired a suite of engineers from Tesla, SpaceX and Anduril....

Elon Musk Has Fired One Of His Top Tesla Lieutenants

by | Jul 4, 2025 |

Elon Musk fired Tesla’s head of operations in North America and Europe, amid declining sales in both regions and the electric vehicle brand’s falling popularity, according to people familiar with the matter. Omead Afshar, who started with Tesla as an engineer in 2017, had become one of Musk’s top lieutenants and was elevated to vice president to oversee business in the two key regions last October. He didn’t respond to a request for comment, nor did Musk or Tesla. Afshar’s removal comes a few days before the end of the second quarter and follows news that Tesla’s EV sales dropped for a fifth consecutive month in Europe. U.S. sales are also down this year and China, the Austin-based company’s top market, saw a 15% drop in May. Equity analysts are anticipating a decline in Tesla’s EV deliveries of at least 10% worldwide in the quarter that ends on June 30, to about 392,800 units compared with 443,956 a year ago. Musk’s close affiliation with and massive financial support for President Donald Trump have negatively impacted the Tesla brand, particularly during his stint running the federal job-slashing DOGE initiative. The company desperately needs to improve its lineup, following the failure of the much-derided Cybertruck to hit volume goals Musk laid out for it, and figure out how to compete with fast-rising Chinese rivals. But rather than add new electric models to boost sales, the world’s wealthiest person has sought to convince investors that the company’s future lies with a new robotaxi service, humanoid robots and AI. It’s a tricky pivot since electric cars, batteries and charging services account for virtually all of...
