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:

# 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")
