Why do your lights keep turning off when you're still in the room? 🤔

If you've ever had to wave your arms at a motion sensor just to keep the lights on, you already know the problem with traditional PIR sensors — they only detect movement, not whether someone is actually there.

Meet the Ai-Thinker Rd-01 — a 24GHz millimeter-wave radar module that actually knows you're in the room, even when you're sitting perfectly still.

It picks up your breathing. Your micro-movements. The tiny signals that prove you're present, even when you haven't moved in minutes.

✅ 24GHz FMCW radar — true presence detection
✅ Detects up to 5 meters
✅ Built-in Wi-Fi & Bluetooth 5.0
✅ No extra microcontroller needed
✅ Tiny 35 × 18 mm — fits inside your existing smart home hardware

Smart switches, automated lighting, security panels, elderly monitoring — the Rd-01 fits right in.

Your sensors deserve a real connection — even miles from the nearest router. 😭

In this video, we break down how the Ra-01SCH-P LoRa module by Ai-Thinker solves the long-range connectivity problem for IoT builders. With +29dBm transmission power and -137dBm sensitivity, it can cover open farmland for kilometers or push data through multiple concrete walls in smart city deployments — all on ultra-low power.

We cover real-world use cases: smart irrigation, utility metering, and remote asset tracking. No Wi-Fi. No cellular fees. Just reliable LoRa.

😤 Has your smart light ever turned off while you were just... sitting there?

You're reading. You're relaxing. You haven't moved in a few minutes — and suddenly, the room goes dark.

This is the #1 complaint about traditional PIR motion sensors in smart lighting. They can only detect large body movements. The moment you sit still, they assume you've left the room.

The fix? Radar.

The Rd-01 by Ai-Thinker uses 24GHz FMCW radar technology — the same principle used in advanced sensing systems — but miniaturized into a module smaller than a credit card.

Here's what makes it different from a standard PIR sensor:

A PIR sensor reacts to heat and large movement. If you stop moving, it stops detecting you.

The Rd-01 radar picks up micro-motions — including the subtle rise and fall of your chest when you breathe. That means it knows you're there even when you're completely still.

Real-world applications our customers are already building with it:
→ Smart lighting that never turns off on you unexpectedly
→ Smart door locks that wake up the moment you approach — before you even reach for the keypad
→ Smart sockets that cut power only when a room is truly empty
→ Occupancy detection for hotel rooms, offices, and meeting spaces

All of this in a module with built-in Wi-Fi + BLE 5.0, so it connects directly to your IoT ecosystem without extra hardware.

If you're designing a smart home product and still relying on PIR, it might be time to upgrade.
