This outdoor wireless solution features a solar cell and is suitable for sensing in areas without power sources.

 Last Mile Communications & Power Supply

A compact wireless solution designed for sensing, featuring a solar power system (solar panel and LiFePO4 battery) and various wireless interfaces.

• Solar-Powered System Requiring No External Power
  The solar power system, consisting of a solar panel, solar charger, and safe LiFePo4 battery, provides an independent power source for the SRPC2 unit and various sensors. With an average current consumption of 40mA, it can operate for 10 days without recharging.
  
• Wireless unit requiring no wiring
  The SRPC2 unit operates autonomously using power from the solar system and LTE-M or low-power wireless communication. No power wiring or cabling is required. The low-power wireless communication range exceeds 1 km line-of-sight. It is well-suited for building outdoor sensor networks.
• Compatible with Various Sensors
  Various sensor devices such as temperature, humidity, wind direction/speed, rainfall, and tags can be connected to the SRPC2 via an interface board. Using a common wireless platform, diverse sensor data collected by multiple SRPC2 child units can be relayed wirelessly and aggregated at the SRPC2 parent unit. The relay function enables wide-area coverage.
  
• Web-based Monitoring
  Collected sensor data is transmitted to a designated server via public networks. Depending on server customization, various operations are possible, including log storage, analysis, visualization, and emergency notifications. It also supports cloud services like Azure and AWS.
