1. Transmitter (Radio)
A simple maintenance-free radio transmitter with an internal battery that is designed to last at least 6 years. The transmitter is capable of receiving data from designated sensors and transmitting it to the receiver located within a range of up to 2 miles. The antenna can be installed up to 20 feet away from the transmitter using an extension cable.

2. Gro-Point™ Soil Moisture Sensors
Volumetric soil moisture sensor based on TDT (Time Domain Transmissometry) provides fast and accurate response to changes in soil moisture. The Gro-Point measures a large soil volume and is suitable for all soil types. Durable and reliable, the sensor requires no maintenance and is designed to remain in the soil permanently or for an entire season.

Gro-Point Soil Moisture Sensors are available in three models:
- GP-MS - for most soils
- GP-SS - for sandy soils
- GP-HS - for clay and saline soils

3. Tensiometer
A special transducer allows accurate and reliable measurement of most traditional tensiometers. IrriWise lets you shift from labor-intensive manual readings to continuous measurement. The system also provides a clear indication when a tensiometer has stopped working.

4. Weather Station
A fully modular weather station supports the following sensors: temperature, humidity, solar radiation, wind speed, wind direction, rainfall, leaf wetness and soil temperature. The IrriWise weather station is self-contained and will operate for one year on (6) AA batteries. Cross-referencing of weather station parameters and soil moisture readings provide a better understanding of plant behavior and can significantly improve the ability to plan a well-based irrigation strategy.

5. Water Meter
Actual reading of water meter installed on a specific lateral or section, providing accurate runtime, volume and flow rate of irrigation events, which can be presented graphically or in a detailed report. This data is critical for cross-referencing between irrigation events and soil moisture readings.

6. Receiver
The base radio receiver is responsible for data reception from the various transmitters and for transferring it via RS232 to the PC computer in the office.

Radio Repeater (not shown in diagram)
A radio repeater is used when it is necessary to extend transmission distances or deal with problematic terrains. The range of the repeater is up to 7 miles. The repeater can be supplied with power either by a 110-240VAC source, battery, or solar panel.

IrriWise™ Graphic Software
The IrriWise graphic software is designed to assist the grower with data-analysis and provide a tool for better management. The software develops a database of collected sensor information that can be graphed as desired. Weather, soil moisture and flow data can be displayed on the same graph. The software also provides trend analysis, disease prediction modules, degree-days, min/max/average, heat units ETo and other calculations.

IrriDial™ Software
A software program that enables remote data download from various IrriWise users. This software automatically transfers the received data to the IrriWise software for easy presentation and analysis.

Radio Manager Software
Radio and network management software, developed especially to enable easy transmitter and sensor definitions, provides continuous indications of data reception and radio performance. The software also enables authorized remote users to download data using IrriDial software.
