Tired of dealing with wired scales and manual data entry? Our latest Bluetooth-powered weighing system leverages BLE/SPP for seamless wireless data transfer—perfect for industrial, retail, or DIY IoT projects!
🔧 Tech Breakdown:
✅ Dual-mode Bluetooth (Low-energy BLE + Classic SPP)
✅ HID-compliant for plug-and-play compatibility
✅ Sub-1% error margin for precision measurements
💻 Developer-Friendly Use Cases:
🔹Smart inventory/logistics tracking (auto-sync to cloud)
🔹Retail POS integration (real-time weight-based pricing)
🔹Hackable for custom projects (e.g., wireless selfie stick triggers!)
📹 Watch the 60-second demo to see the module in action:
🛠 Want to Build This?
🔹Recommended chipsets: nRF52, KT6368A, ESP32 (BLE+SPP support)
🔹Protocol deep dive: How we optimized throughput to avoid lag
# Sample BLE data capture snippet (Python + Bleak)
async with BleakClient(scale_address) as client:
weight_data = await client.read_gatt_char(CHAR_UUID)
print(f"Live weight: {int.from_bytes(weight_data, 'big')}g")
Let’s discuss! **👇
🔹Would **Bluetooth mesh make sense for multi-scale setups?
🔹Best practices for minimizing interference in industrial environments?
