Solar WXLink LoRa - Wireless Data Link designed for the WeatherRack and the WeatherBoard - Grove
NOTE: The unit is shipped with a simple wire antenna on each LoRa transceiver. This is good (depending on your environment, walls, etc) to about 30m. Above 30m you may want to consider another antenna (although test it first. You may be OK!) such as our Yagi Antenna. You can add a Yagi at both ends to really blow out the range. 6000 meters or even further depending on the height of the antenna and environment. You need to try it and see.
What is the Solar WXLink LoRa?
The Solar WXLink is a solar powered wireless serial link that can transmit up to 6000 meters in free air, with the proper antenna (like our Yagi Antenna product). It is designed to connect up to any source of data from sensors connected to the Mini Pro LP Arduino compatible low power computer board. It was specifically designed to connect a WeatherRack weather sensor array to a Weather Board based system connected to an Arduino or Raspberry Pi computer. The receiver is read by the host computer through an I2C interface. Much easier and more available than a serial interface. And yes, it has Grove connectors throughout the system. The WXLink LoRa comes preloaded with the software to support a WeatherRack and AM2315. See below for the source code. No soldering required.
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 data.
The serial link is bi-Directional although the software currently just supports a uni-directional link.
This kit contains:
- Two Mini Pro LP Arduino Boards
- One DS3231 Real Time Clock
- 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 Cable from SunAirPlus to Mini Pro LP Rx Arduino Board
- Two 330mA/6V Solar Panels with JST-2 Plug for SunAirPlus
(Note: The second Solar Panel is for those locations with more than average cloud cover. It is optional to install. If you wish to install it, you will need to solder two wires from the positive (+) on one solar panel to the positive (+) on the other panel and the negative (-) on one solar panel to the negative (-) on the second panel as in the picture below.).
Or you can buy the inexpensive Multi Solar Panel Connector (for up to four panels).
