- lower cost research-grade multi-parameter sensor - Measures moisture, temperature and EC - Digital SDI-12 for easy system integration - Rugged and low power - Accurate monitoring of soil conditions - Detachable and extendable cable system - 5 year warranty - The digital multi-parameter WET150 soil sensor represents the culmination of forty years research and development at Delta-T Devices. Through a number of key design innovations it delivers research-grade accuracy and build quality at a price point not previously thought possible. It is the ideal sensor for research of soil conditions – and for integration into SDI-12 environmental and horticultural measurement/control systems. When buried in soil or substrate the WET150 Sensor simultaneously measures three crucial variables that influence plant growth: moisture content, temperature, and electrical conductivity (EC) – a strong indicator of the general nutrient level. The WET150 is also available in kit form with meter.
When installed in growing media, the WET150 can provide the accurate data required to power effective SDI-12 enabled automatic precision irrigation and environmental control systems – enabling reduced use of water/fertilizer whilst improving yields and quality of produce.
The rugged watertight build of the WET150 also makes it ideal for use in field research and outdoor farming – sensors can be left buried over very long periods of time without loss of performance. WET150 sensors can also be buried at different depths to enable monitoring of soil moisture, temperature and EC profiles.
The WET150 is a digital SDI-12 sensor (fully compliant with SDI-12 version 1.3 standards). SDI-12 is a standardised interface for connecting digital sensors to a master device – typically an SDI-12 compatible data logger, wireless node, controller, or computer. 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 SDI-12 enabled master device – cutting costs and complexity.
The WET150 (like all SDI-12 Sensors) is low power and features an integrated microprocessor that enables it to perform two way communication with an SDI-12 master device.
The WET150 outputs readings in a standard SDI-12 format which can be sent to, and recognised by, the master device. The inclusion of a microprocessor also gives the WET150 the ability to perform complex internal correction, compensation and averaging algorithms that enhance the quality of the data.
SDI-12 protocol is based on a master-slave configuration. When installed in an SDI-12 network, individually addressed WET150s (slaves) are sent data requests by the master device. These requests briefly wake all WET150s in the network – and result in a measurement and data sending response from the targeted WET150. When not responding to a master request, all WET150s remain in a dormant energy saving state.
Soil science – The WET150 is easily integrated into SDI-12 systems and delivers research-grade accuracy and reliability for researchers monitoring soil or substrate conditions. Typical areas of use include irrigation research, crop trials, phenotyping, hydrology, soil water profiling, and forestry.
Horticulture and Agriculture – The WET150 Sensor is available with a comprehensive set of calibrations and provides a simple, effective, rugged solution to checking the uniformity of growing conditions for many types of growing media. The WET150 excels in measuring the variables required to monitor and control fertigation. It is also a powerful tool for sampling soil salinity levels (which can affect crop yields).
Precision Irrigation – The WET150 sensor is ideal for precision irrigation applications. The WET150’s compact design allows it to be easily installed in grow bags. The WET150’s accurate sensor data can be used to optimise irrigation scheduling, or drive an SDI-12 enabled automatic irrigation system.
System integration – The WET150’s accurate and stable three parameter measurement, simple SDI-12 output and low power make it the ideal sensor for system integrators. Industrial rated, UV resistant cable fitted with a waterproof IP68 connector allows the sensor to be buried indefinitely, whilst still permitting easy cable exchange or extension if necessary.
