You're inside, the garden's out there, and you have no idea if it's bone-dry or waterlogged. That's the gap this sensor closes. The XC0439 plugs into your Jaycar Smart Weather Station (XC0438 or XC0450) and streams soil moisture plus ambient temperature readings straight to your phone via the Tuya platform. No wiring runs, no guesswork. The unit sits higher above the soil line, which gives you a cleaner wireless signal and more reliable data than a sensor buried in the dirt. Set it up in a few minutes, check your beds from the kitchen, and stop over-watering or letting the tomatoes crack in a heatwave. Add to cart and get your watering schedule sorted before the next dry spell hits
