Greet. Inform. Alert. Automatically.

Imagine this: a customer walks into your store, and instantly a friendly voice welcomes them, announces a special promotion, or reminds them to wear a mask. No button to press. No staff needed. Just automatic, professional communication that creates a better customer experience.

That’s what our Motion Sensor Voice Announcer does.

How it works

The built‑in PIR infrared sensor detects human presence within a 0‑6 meter range and instantly triggers the voice playback. Walk past – it speaks. Move on – it stops. Simple, reliable, and hands‑free.

Your message. Your way.

Connect the device to your computer via Type‑C cable and upload any MP3 file – sales pitches, safety warnings, directional instructions, or even festive greetings. With 4MB of storage, you can store multiple tracks and switch between them anytime.

Perfect for high‑traffic locations

• Retail stores & supermarkets – announce daily deals or guide customers to promotions
• Gas stations & service areas – remind drivers of safety rules or payment procedures
• Transport hubs – provide directional information or emergency alerts
• Corporate lobbies – greet visitors automatically with a professional first impression

Built for everyday use

Rated at ≥85dB (within 1 meter), the audio cuts through ambient noise. Choose from two power options – Type‑C 5V/1A adapter or 3 AAA batteries. In standby mode, it consumes less than 100μA, ensuring months of operation without frequent battery changes.

Install in minutes – no electrician needed

Use the included adhesive tape or optional bracket mount. Place it on walls, shelves, counters, or entryway pillars – wherever your customers pass by.
