sgpcard on Instagram: "🚨 FEATURE 10 / 1000 — Wi-Fi CSI ALARM 🚨
This is no longer science fiction. This is real technology.
Today we show you one of the most powerful features of the SGP Card Mini:
👉 Turning your home Wi-Fi into an invisible alarm system.
🧠 What does the SGP Card Mini do?
The SGP Card Mini analyzes all Wi-Fi networks around you. It does not connect to them:
✅ It observes them
✅ It measures them
✅ It interprets them
Thanks to Wi-Fi CSI (Channel State Information) technology, the card can detect any change in the environment.
🏠 What does this mean in real life?
You can detect human presence:
✔️ In a single room
✔️ In a whole house
✔️ Even when the person is moving
✔️ Without cameras
✔️ Without PIR sensors
✔️ Without anyone carrying any device
📡 How does it work?
As we explained in other videos:
When a person moves, they block, reflect, or distort Wi-Fi waves in the environment.
This creates interference in the signal.
The SGP Card Mini detects this interference, processes it, and:
➡️ Sends it to a server
➡️ The system analyzes it
➡️ And it becomes a real-time presence alarm
🚨 In other words:
👉 If someone enters your home, even without touching anything, the system knows.
💳 What do you need to use it?
You need an SGP Card Mini.
And the best part:
🔥 Anyone who owns the card will have access to the code to use this feature.
🔥 And not only this one: thousands of other projects and features are available or in development.
🧩 This is not just an alarm.
This is a technology platform to build things that do not even exist yet.
⚠️ And this is only feature 10 out of more than 1000.
