Smart Orchard Tech Providers & Sensors

Learn more about the sensors being deployed at the 2021 Smart Orchard

In our last post we talked about the goals for the 2021 Smart Orchards Project @ Washington Fruit & Chiawana / Columbia Reach alongside researchers at the WTFRC & WSU. To properly inform growers with data it is crucial that IoT agtech sensors are strategically deployed throughout orchard blocks. These IoT agtech devices harness data that ultimately obtain a more precise allocation of resources to increase fruit yields and quality while saving money on irrigation, chemicals, labor, etc. Once this data is harnessed, the next critical step is for innov8.ag to compare all of the data from each tech or imagery provider to get a side by side comparison. This will allow us to pinpoint data accuracy and the viability each sensor has for a growers usability and price points. Continue reading below to learn more about each sensor.

ATMOS 41 ATMOS 14

The ATMOS 41 micro climate weather stations is a small, affordable, easily installed, and durable weather station with 12 different weather variables. It was designed for continuous deployment in harsh climates, such as Africa, which means there are no moving parts to fail. Reliability and maintenance are simplified because there’s never any mechanical wear. Plus, the ATMOS 41 weather station is accurate. Specialized pins made of real gold measure every drop of rain. The 0.017 mm resolution means it can accurately measure small rainfall and even heavy dew events that other rain gauges miss. And, no moving parts means the ATMOS 41 anemometer is accurate at low wind speeds. Installation is also simplified as it has plug and play capabilities with near real-time data access from the cloud when used with the ZL6 data logger.

Using such a station allows the grower to obtain a variety of weather variables without having to constantly manage wear and tear on the device. This gives the grower more informed decisions with less to deal with.

The ATMOS 14, in-canopy weather station combines air temperature, relative humidity, barometric pressure, and vapor pressure all into one sensors. The Atmos 14 is a low-maintenance and rapid sensor designed to take temp/RH measurements. By keeping this sensor compact and durable, the grower can collect data even in tight, hard to reach places. Setup is simple as it has plug and play capabilities with near real-time data access from the cloud when used with the ZL6data logger.


TEROS 21

A true full-range water potential sensor that’s low maintenance and low cost




The TEROS 21 water potential sensor is incredibly easy to use. It requires no maintenance, and it’s accurate enough for most applications. In fact, the TEROS 21 provides an even more accurate soil moisture picture than measuring water content alone. A water content sensor only shows the percentage of water in the soil, but add a TEROS 21 water potential sensor, and you’ll know if that water is available to plants and where it will move. Plus, unlike water content, matric potential isn’t dependent on soil type, so you can compare moisture between different sites. Not only that, the new Gen 2 version boasts an improved circuit, a more robust microprocessor, and an improved measurement range. It now measures all the way from near saturation to air dry (−5 to −100,000 kPa) making it the world’s first true full range water potential sensor.


PHYTOS 31

Diseases and infections can destroy an entire crop, but at the same time, applying fungicides is costly and time-consuming. If you’re deciding when to spray by monitoring leaf wetness with a resistance grid sensor, you’ll have trouble accurately determining wetness duration without a lot of extra work.


The PHYTOS 31 lets you know leaf wetness in no uncertain terms. It measures both the onset and duration of wetness on a simulated leaf, which in turn predicts when the onset of certain diseases or infections may occur. It’s not only a more accurate instrument, it’s also the easiest to set up, making it a simple and straightforward solution to several problems.

FloraPulse- Microtensiometer

The FloraPulse system is a microchip tensiometer (microtensiometer) that is embedded into the tree woody tissue and directly measures the water status, known as water potential. Because the measurement is taken directly inside the water-carrying tissue, readings are very accurate and reliable. Growers receive daily midday stem water potential readings, along with science-backed irrigation recommendations.




Meter Group- ECH20 EC-5

The EC-5 determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. Its 70 MHz frequency minimizes salinity and textural effects, making this sensor accurate in almost any soil or soilless media. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.


Edaphic Scientific- Dendrometers

With a Trunk Dendrometer (top image), Stem Dendrometer (middle image), and a Fruit Dendrometer (bottom image), the Smart Orchard collaboration is able to measure:

  • Micro-variations of trunk radius in micron range

  • Tree trunk or stem diameter variations against

environmental variables

  • Stem growth dynamics

  • Ability to record both size and growth rate of intact rounded fruits in three diameter ranges within 7 to 160 mm.

  • The effect of irrigation rate and other environmental factors on both water balance and growth of fruits.

SapIP-IRT – Infrared Temperature Sensors -

Dynamax has created three new transpiration, leaf canopy monitoring systems. Each system observes the IRT leaf canopy and the weather and produces data for precision ag management. Crop water stress index (CWSI) and degrees above non stressed (DAN) plant stress models are available to determine if, and when, your crops need irrigation, stress from deficit, or high ambient temperatures.


About the SapIP-IRT

Up to (6) IRT analog sensors can be added to the SapIP wireless system nodes. As part of a SapIP wireless network, plant sap flow or water use, soil moisture profiles, ET weather, and IR leaf temperature, can all be monitored simultaneously in one wireless system. If SapIP nodes are used as data loggers for the IRT sensors, data can be uploaded to the AgriSensors.NET webpage. SapIP nodes can also be “daisy-chained” several levels deep, thus allowing distances of 2-3 miles to be monitored. SapIP systems are versatile and flexible, and can be configured to meet your particular requirements.


DEX100 – Dendrometers

The DEX20, DEX70, DEX100 and DEX200 are highly precise electronic dendrometers that measure the growth and size of plant stems and fruits. The effects of environmental factors on the water balance of plants and stem size variations over time are easily monitored with a temperature compensated dendrometer.


The DEX is a caliper-style device with a full bridge strain gage attached to a flexible arm. The output signal is then recorded by a data logger or computer in real time. The millivolt sensor output shows both the diurnal and long term growth of the plant. The device has been used to test plants under conditions of water stress, elevated ozone and other atmospheric pollutants. Applications for screening plants for growth rate and stress tolerance are also common.


SM150T – Soil Moisture Sensors -

The new SM150T measures soil moisture and temperature with research-grade accuracy. It offers stable, robust and reliable performance at a great price.


The new SM150T’s advanced patented electronics and tough build produce a highly dependable sensor with exceptional salinity and temperature stability. The SM150T is engineered to withstand long term burial – the sensor, connectors and cable are all environmentally protected to IP68. It offers moisture accuracy of ± 3% (after soil specific calibration) and the built in temperature sensor achieves ± 0.5° C.

The SM150T is a dual purpose probe – it can be used portably for instant moisture readings, or left installed in the soil connected to a data logger, to provide long-term moisture and temperature data.


MICRO2 – Weather Station -

Dynamax, Inc. produces the new SapIP wireless data logger network for measuring plant water use, IR leaf temperature, soil moisture, and weather. The SapIP-MICRO system is a wireless node with RH and air temperature included. If you want, you can add soil moisture, soil temperature, solar radiation, wind speed and direction, and rainfall sensors as well.


This sensor set can then be used to calculate ETp for irrigation scheduling for crops or trees. The nodes can be spaced up to 400 meters apart and daisy-chained, giving a total distance of over a mile. The SapIP-MICRO is an excellent research grade weather station, and data can be collected directly from the node, or through the Internet.
