IRT – IR Leaf Temp System

• Wireless IR Temperature

• Leaf temperature

• Plant stress measurement

• Irrigation scheduling

• For center pivot or other irrigation systems

• Uses low-cost Zigbee coordinators

• Developed with USDA-ARS

Dynamax IRT Sensors • Measure IR temperature ±0.5° C

• 20 degree Narrow Field of View

- 6 ft. distance gives a 2 ft. window

• Leaf temperature relates to plant stress

• Wireless, Analog, or SDI12 versions

• Compare to CWSI or other Stress Models

• Excellent for use with drip or center pivot irrigation

• For use on crops where sap flow will not work, or on

moving platforms

• Works with 2 watt solar panel (separate),

Wireless SPIP-IRT has charger and batt included.

RHT Microclimate Node • RH & Temperature node (SPIP-RHT)

• High Precision sensors

– .1 C Temp accuracy for ambient – Replaceable Rotronic RHT sensor

• For calculation of CWSI or VPD

Vapor Pressure Deficit

• Wireless connection to SALH Logger or Coordinator

• SPIP-RHT includes batt /charger

SALH System Configuration

BASIC Data Collection IRT Sensors add Leaf Temperature and Leaf Stress

Levels

High Stress = Temperature above ambient or non- stressed plants

Direct Addition to Empirical CWSI crop stress model

Or Degrees Above Non Stressed (DANS) crop stress model

Useful when sap flow data or actual plant water use data is not available

CWSI = 0.4 to 0.6, “0” is no stress 0.5 = 50% reduction in water use Charts color coded for easy

interpretation

dT UL- Upper limit dT LL – Lower limit

CWSI - Plant Stress Data Analysis

Simple Data Presentation

Plant leaf temperature vs :

1) Total water stress CWSI

CWSI = 1- Ea/Ep = Actual Transp./Transp. Potential

Growers need only decide how much CWSI can be tolerated before irrigating (0.4 to 0.6)

Water can be conserved if irrigation schedule is reduced, and Stress Factor remains neutral

CWSI = (40-30)C – (5 C) = 0.50 (15 C) – (5 C) Significant Stress depending on plant

dT m = Max (T – Tair)

40° C

Air = 30° C Air = 30° C

35° C

CWSI = 0.0 No Stress (TLL=5 C)

Ex below: TUL=15C TLL=5C

2) DANS = Degrees Above Non-Stressed plants Stress Factor = higher temperature above well watered plant (Degree-Hours)

Leaf = 40° C

Air = 30° C Air = 30° C

Leaf = 35° C Above well watered DANS = 5.0 C

iDANS = Integrated Degrees Above Non-Stressed plants (Show here as WSI= 22.3° C)

Coordinator SPIP-IRT-COR

SapIP Coordinator Module

• Coordinator connected to PC – USB, or irrigation controller. Smart controllers have program changes based on temperature – CWSI algorithm

• “IRT Watcher” Software collects files to PC

• 300 to 500 meter “Line of Sight” with outdoor antenna (IRT-ACC24-EW)

• Use Routers to add distance, 300 - 500 m

• Up to (27) IRT possible with (3) Routers

IRT Watcher Software

• Install on PC or Industrial control PC with Windows

• Set up communications from USB to Coordinator

• Retrieve records for each IRT node

• Save all data into .csv files for Excel, attaching date and time

• Can do setup and network commands, such as “Sample”

command, and “Network Reset”

Leaf Temperature for Cherries (Black) is 4 degrees above ambient (Green) not well watered Leaf Temperature for Almonds (Blue) is below ambient (Green) – well watered.

3 IRT Sensor Models

1) Wireless IRT – Zigbee (SPIP-IRT) • Output = Serial #, Battery Volts, T-Target, T-Body • Must obtain a Coordinator in Zigbee and a Router for

every +9 nodes

2) Analog IRT Sensors (SPIP-IRT-AD) • Temp in Analog – For conventional signal loggers, two

wire signal. (-40° to 60° C = 0 to 1 V)
