Practical Application Scenarios
1. Large-Scale Farm Soil & Meteorological Monitoring System
This LoRa module matches Ebyte E50 low-power acquisition sensors to build long-distance agricultural IoT networks. The 10km transmission range covers vast farmland without wired wiring, and ultra-low 3uA sleep current supports solar battery-powered field probes. Farmers transmit soil humidity, PH value and meteorological data to central gateways stably via E220-900T30S, and carrier monitor function avoids signal collision between dozens of field sensor nodes.
2. Urban Intelligent Street Light Mesh Control Project
Paired with Ebyte E160 remote control modules, the unit forms multi-hop LoRa street light control networks for municipal engineering. Its 30dBm high transmit power ensures stable signal transmission across building blocks, industrial wide temperature range (-40 to +85 Celsius) adapts severe outdoor climate. Air wake-up technology keeps street light terminals in deep sleep most time to cut power consumption, while remote dimming and fault reporting data can be uploaded to city management platforms over kilometers.
3. Industrial Park Equipment Vibration & Temperature Monitoring
Integrated with PLC or Ebyte RS485 data acquisition DTUs, the module collects running status data of production machines in large factories. Long 10km communication distance eliminates complex cable laying inside sprawling workshops; LoRa spread spectrum anti-interference performance resists electromagnetic noise from motors and welding equipment. RSSI feedback helps engineers judge signal attenuation between monitoring nodes and central control cabinets accurately.
4. Mountain Water Conservancy Hydrological Data Collection
Combined with Ebyte water immersion and liquid level sensors, it serves reservoir, river and mountain flood monitoring stations. Wide 2.3V-5.5V voltage input fits small solar power systems deployed in remote mountain areas. Stamp hole SMD packaging allows compact integration inside waterproof sensor housings, and long-distance wireless transmission sends real-time water level and rainfall data back to hydrological management offices dozens of kilometers away.
FAQ Section
1. What is the maximum actual communication distance I can get with E220-900T30S?
The rated 10km distance is tested under open line-of-sight conditions with 5dBi antennas and 2.4kbps low air rate. If there are buildings, trees or metal barriers, the effective transmission range will decrease accordingly. Users can match high-gain IPEX external antennas to recover signal penetration performance.
2. Is this LoRa module compatible with 5V single-chip microcontrollers directly?
The module uses standard 3.3V TTL UART level. Direct connection with 5V MCU IO pins will cause permanent hardware burnout. Level conversion circuits or voltage divider resistors must be added between the module and 5V main control chips.
3. Can Ebyte provide customized firmware for E220-900T30S?
Yes, custom development service is supported. Our R&D team can adjust working parameters, modify transmission logic, add proprietary communication protocols or optimize sleep modes according to customer project demands, with mass production sample testing available before formal orders.
4. Which RF certifications does E220-900T30S hold for overseas shipment?
This LoRa module has completed official FCC certification for North American markets, and it meets CE RF standard requirements for EU regions. Customers can apply KC, NCC local certifications based on our original test reports to simplify export filing procedures.
