Truebner products for precise irrigation
Truebner stands for high-quality sensor technology relating to soil moisture, temperature, humidity and RS485/Modbus. These are the right tools for OpenSprinkler Shop customers if irrigation should not only be automatic, but also measurable and intelligent.
Why Truebner?
If you don't want to estimate soil moisture, climate and weather data, but rather measure them accurately, Truebner sensors are a very strong basis. Especially in combination with OpenSprinkler, watering times can be adapted much better to plants and locations.
- Precise soil moisture instead of flying blind
- RS485/Modbus for robust installations
- For garden, greenhouse, agriculture and professional applications
- Can be combined with OpenSprinkler, RS485 adapter and suitable extensions
