This design uses SunAirPlus which collects (and transmits the information back to the weather station)
information on the power system (Solar Panel Voltage/Current, Load Voltage/Current, Battery
Voltage/Current). A GREAT science project! Lots of dataThe serial link is bi-Directional although the software
currently just supports a uni-directional link.
This kit contains:
•
One Mini Pro LP Arduino Boards
•
One WXLinkWR Weather Rack Interface Board
•
Two Grove 433MHz LoRa boards
•
5 20 CM Grove Cables
•
SunAirPlus Solar Panel Controller / Data Collector (includes Pin Header to Grove Plug Cable)
•
USB Type A Cable from SunAirPlus to micro USB Mini Pro LP Rx Arduino Board
•
Two 330mA/6V Solar Panels with JST-2 Plug for SunAirPlus
•
Multi Solar Panel Connector Board
Grove 433MHz LoRa Transceiver
The main functional module in the LoRa Radio 433MHz is RFM98, which is a transceiver features the LoRa
long range modem that provides ultra-long range spread spectrum communication and high interference
immunity whilst mini-missing current consumption. The CPU on board the LoRa Radio 433MHz is an
ATmega168,
There is also an integrated a s wire antenna to receive and transmit the signal, if the signal is too weak to
receive,, you can use the MHF connector next to the wire antenna.
This is the 433MHz version.
Note
• Keep the antenna vertical to the board and as straight as possible
• Avoid having any big metal object near the antenna
Features
• Uses RFM95 module based on SX1276 LoRa®
• ~28mA(Avg) @+20dBm continuous transmit
• ~8.4mA(Avg)@standby mode
• ~20mA(Avg) @receive mode, BW-500kHz
• Simple wire antenna or MHF Connector for external high gain antenna
• +20dBm - 100 mW Power Output Capability
