WET150 Sensor Digital SDI-12 Interface Use many sensors with just a single master device, reducing complexity and costs. Low power systems that run off battery and are powered via the interface Bus. Many parameters can be transmitted over simplified wiring. SDI-12 defines both the digital communications and sensor power standards. A key strength of SDI-12 is that it supports the connection of multiple networked sensors to a single input on a master device. No loss of accuracy over large cable runs. Ideal for wireless comms based applications The WET150’s sharp and strong pins minimise soil and...
