Sentek PLUS Introduction

Background

Sentek PLUS combines the scientifically and commercially proven sensor technology of EnviroSCAN, with

web enabled, wireless communication.

In addition to this, Sentek PLUS also has the ability to continuously track fertilizer / salinity data through the

use of TriSCAN sensors. Sentek PLUS can utilise GPRS or NextG communications to send soil water and

fertilizer / salinity data from the probe to the users PC via the internet. Alternatively, it provides for direct in-

field download when services become unavailable in regional areas.

Sentek PLUS Introduction

Hardware Requirement Lists For Sentek PLUS

Sentek PLUS Serial Connection (Front Panel Download)

As an alternative to downloading using the Internet, it is also possible to download by directly connecting

your computer to the front panel connector on the Sentek PLUS Data Transmission Unit (DTU). This is

typically done with a portable computer. For further Information on how to do this please refer to the Data

Exchange manual.

CDMA Support

The Australian CDMA network has been shutdown. Consequently there is no longer a CDMA modem

certified by Sentek for use with Sentek PLUS systems.

Sentek PLUS systems, with probe firmware version 1.2.3 or later, should work with CDMA modems

provided they are in an area with CDMA network access and Probe Configuration Utility Network tab has

been appropriately setup.

For further information about using existing CDMA units see "EnviroSCAN Plus NextG CDMA Upgrade

Guide".

Required parts to assemble a complete System

Sentek PLUS front panel and DTU housing

12V 7.5 AH Sealed lead acid battery

Mounting Pole

12V Solar Panel & Solar Panel Bracket

Solar panel bird deterrer

5m Length of Data cable to connect the probe (with connector)

Ferrite bead for cable

Optional GPRS or NextG Modem

Antenna with cable
