Introduction

The global smart pet feeder market is projected to grow at 12.5% CAGR (2023-2030) as pet owners increasingly adopt IoT solutions for pet care. A key challenge in this sector is ensuring reliable food dispensing, portion control, and remote monitoring – all while maintaining connectivity in areas without Wi-Fi.

EBYTE’s 4G-enabled smart pet feeder solution combines:
✔ E840-DTU(EC05-485)E – High-reliability 4G DTU for remote control
✔ Cloud platform integration (AWS IoT/AliCloud) for data analytics

EBYTE Product Recommendations

E840-DTU(EC05-485)E – 4G Cellular Communication Module

Key Features:

  • Network Support: LTE Cat 1 , fallback to 2G/3G

  • Data Interfaces: RS485 + RS232 (connects directly to load cells & MCUs)

  • MQTT/HTTP Protocols: Seamless integration with AWS IoT, OneNET, AliCloud

  • GPS Optional: Track feeder location (anti-theft)

  • Industrial-Grade: -40°C to +85°C operation (outdoor/indoor use)

Why 4G (Not Wi-Fi)?

  • Works in garages/barns without Wi-Fi coverage

  • No dependency on home network stability

Key Functional Workflows

Feature

Technical Implementation

Scheduled Feeding

Cloud sends MQTT commands → DTU triggers motor at set times

Portion Control

Load cell detects weight → Stops motor when target grams dispensed

Food Alerts

DTU sends SMS/APP alert when food <10% capacity

Theft Deterrence

GPS location tracking (optional E840-DTU-GPS model)

Cloud Platform Options

  • OneNET (China market) – Low-latency control

  • AWS IoT (Global) – HIPAA-compliant data security

  • Private Server – For white-label solutions
