This school year, W1HLO worked on a couple of enhancements for our repeater. One of the projects was a solar-powered weather station that could speak the current weather conditions over our repeater. (Note: Our repeater is accessible on 441.950 MHz out +5 MHz offset with a PL of 67 Hz.) Megan KC1NJR and Shaylin KC1NJS headed up this project and recently put it on the air.
The weather station uses an Argent Data Systems ADS-WS1 that has been configured to speak the weather conditions every 30 minutes and when the wind speed changes > 10mph. The ADS-WS1, battery, radio, and charge controller are all mounted in a waterproof toolbox. The ADS-WS1 is wired to a Baofeng UV-5R programmed to the repeater's frequency. You can see a doodled wiring schematic below:
A 90 Watt solar panel connected to a charge controller and a 12V gel cell battery provided power to everything. A 12V battery eliminator was used to easily convert the UV-5R to 12V usage. (Note: The 12V plug and socket for the UV-5R battery eliminator should probably be removed and hard-wired together as the plug had to be taped to the socket to ensure a good connection.) A doodled wiring schematic follows:
To program the ADS-WS1, we wired a programming cable as follows:
