Smart Digital Weight Scale

Telary Technologies > Portfolio > Smart Digital Weight Scale

 

1. Overview / Objectives

Weighing scales have evolved from simple measuring devices into “Smart Node” systems. They are no longer just for weighing; they are data-entry points that integrate directly with inventory, medical, and logistics software.

The primary use cases and unique objectives of include:

  1. Logistics, Warehousing & Shipping

In high-volume environments, the objective is to eliminate “stationary scale” bottlenecks.

  • Mobile Dimensioning: Bluetooth scales integrated into mobile carts or hand trucks allow workers to capture weight at the point of handling.
  • ERP/SAP Integration: Data is sent directly to management software (like SAP or Oracle) via a Bluetooth-to-Cloud gateway, updating shipment records in real-time without manual typing.
  • Error Prevention: Systems can automatically flag discrepancies between the “expected” weight in the database and the “actual” weight, reducing shipping fee penalties.
  1. Healthcare & Remote Patient Monitoring (RPM)

Clinical scales focus on high-fidelity medical data and patient privacy.

  • Automatic EHR Syncing: Scales in clinics send weight and body composition data directly to Electronic Health Records (EHR) like Epic, ensuring doctors have instant, accurate data.
  • Nerve & Heart Health: Commercial medical scales monitor arterial health (Pulse Wave Velocity) and Sudomotor function (nerve health) to screen for chronic conditions like diabetes complications.
  • HIPAA Compliance: These scales use encrypted Bluetooth profiles to ensure that a patient’s sensitive health data is never exposed during transmission.
  1. Commercial Kitchens & Food Service

Objectives here focus on waste reduction and standardization.

  • Inventory Control: Smart scales monitor real-time consumption of raw materials. When a chef weighs out ingredients, the system automatically deducts that amount from the digital inventory.
  • Recipe Consistency: Bluetooth scales connect to kitchen tablets that walk staff through recipes. The “Next Step” in the recipe only triggers once the scale confirms the exact weight of the ingredient has been added.
  • Waste Tracking: Integrated systems track “return-of-surplus” food to calculate the exact cost per guest and identify where ingredients are being wasted.
  1. Retail & Point of Sale (POS)
  • Smart Invoicing: Bluetooth platform scales connect to tablet-based POS systems. The weight of bulk items (produce, grain, hardware) is pushed directly to the checkout screen to generate an instant, tamper-proof invoice.
  • Legal for Trade (Legal Metrology): Commercial scales are “Class III” certified, meaning they are legally calibrated to ensure customers aren’t overcharged—a requirement for any business selling goods by weight.

2. Solution

The Smart Digital Weight Scale Solution is designed and implemented as a complete hardware-to-cloud system, integrating load cells, high-resolution (24-bit) ADC, Bluetooth, embedded firmware, and a user-friendly mobile application.

Hardware & Mechanical Design

  • A Load Cell (strain gauge sensor) and High-resolution (24-bit) ADC that serves as the sensing unit for applied weight.
  • Microcontrollerfor sensor interfacing, local processing, and communication.
  • Supports Bluetooth connectivity for real-time data transmission.
  • Custom compact mechanical enclosure designed for discreet indoor deployment.
  • Low-power design suitable for continuous operation.

Embedded Firmware

  • Continuously samples weight measurements from the weight sensor (Load Cell + ADC) as per gain selection.
  • Filters noise and false triggers caused by sensor or environmental variations.
  • Securely publishes weight data over Bluetooth interface.
  • Supports remote configuration and firmware updates.

Backend & Data Management

  • Uses known weights to establish a conversion factor (counts per gram/kg) to translate raw data into meaningful weight units.
  • Provides APIs for integration with third-party systems such as Logistics, Warehousing & Shipping, Healthcare & Remote Patient Monitoring (RPM), Commercial Kitchens & Food Service, Retail & Point of Sale (POS) etc.

Mobile Application / Web Application / Frontend

  • Dashboard displays:
    • Real-time weight
    • Hourly, daily, and weekly footfall trends
    • Entry vs exit analytics
  • Supports role-based access for administrators and facility managers.

Enables monitoring across multiple locations and devices from a single interface.
