EBYTE E220 Series LoRa Modules

Product Overview

The EBYTE E220 Series is an industrial-grade LoRa module based on the Semtech SX1262 chip, designed for low-power, long-range wireless communication. It is ideal for smart agriculture, environmental monitoring, and similar applications.

Key Features

• Long-Range Transmission: Supports 1–5 km line-of-sight communication with strong penetration capabilities, suitable for farmlands and greenhouses.

• Ultra-Low Power Consumption: Sleep current as low as 1.5μA, compatible with solar power for long-term unattended operation.

• Anti-Interference: Utilizes LoRa spread spectrum technology for stable performance in 433MHz/470MHz/868MHz/915MHz frequency bands.

• Flexible Configuration: Adjustable parameters (frequency, data rate, power) via AT commands; supports UART/TTL interfaces.

Model Comparison

Temperature/Humidity Sensor (DHT22/SHT30)

• Measurement Range:

• Temperature: -40°C to 80°C (±0.5°C)

• Humidity: 0–100%RH (±2%RH)

• Output: Digital signal (I2C/1-Wire), compatible with MCUs.

• Applications: Greenhouse climate control, storage monitoring.

Light Sensor (BH1750/MAX44009)

• Measurement Range:

• BH1750: 0–65535 Lux

• Applications: Light intensity monitoring, smart lighting systems.

System Design & Deployment

System Architecture

• Sensor Nodes: Temperature/humidity/light sensors + MCU (e.g., STM32/ESP32) + E220 module.

• LoRa Gateway: E220 module + Raspberry Pi/NB-IoT module for data aggregation and cloud upload.

• Cloud Platform: Data visualization, threshold alerts, and remote control via platforms like Alibaba Cloud or ThingsBoard.

Power Supply

• Solar Power: 5W solar panel + 18650 battery for outdoor operation.

• Low-Power Design: Sensors wake every 10 minutes; LoRa modules activate only during data transmission.

Deployment Guidelines

• Sensor Placement:

• Install nodes every 50m in greenhouses at crop canopy height.

• Deploy along field edges in open farmland, avoiding direct water exposure.

• Anti-Interference Measures:

• Mount antennas vertically away from metal obstructions.

• Use IP65-rated enclosures for waterproofing.
