Camalie Networks System 3 (CS3)
Camalie Networks System 3 is available now. It provides growers with a low cost, scalable, open system, for monitoring and control of agricultural operations.
The CS3 system consists of three major components:
The CS3 Field Stations have the sensors and/or actuators connected to them. They can be placed anywhere within 2 miles line of sight of the gateway or within 2 miles of another field station which has a path back to the gateway. The CS3 Internet gateway acts as a relay to pass data from field stations to a Camalie Networks' server or commands in the opposite direction. It requires no static IP address or firewall reconfiguration at your site or any cellular subscription. Just plug it in, turn on your nodes and go to your Camalie Networks Web Site to access your data, and/or control your irrigation system.
There are 3 different CS3 field station models, the Z, ZX, and Terraduino. They all use standard XBee 900HP 900MHz radio modules with DigiMesh self organizing mesh technology. The Z model is a basic model for data acquisition. The ZX model has an arduino compatible base board with a microcontroller, XBee radio, and solar power supply.
Thus, far Camalie Networks has used the Z model for well pump control, temp and soil moisture monitoring and has used the ZX for water metering, valve actuation, water level monitoring, remote data display, and GPS tracking of vehicles. The ZX node counts switch closures and reports switch position every 15 seconds. This function can be used for monitoring door/gate/window security as well as water metering. The GPS monitoring function is useful for keeping track of vehicles especially where cell coverage is incomplete and a record of paths needs to be saved. Nodes can be easily placed to cover hilly wooded terrain using a connectivity indicating LED visible on each node.
All of the field stations are powered by three NiMH batterys charged by a solar panel. Typical battery life with no sun is 3-6 weeks depending on sensors and interface card installed. Battery life with sun is typically 4 years.
Below are pictures of the CS3-ZX field station.
Below is a picture of a CS3-Terraduino integrated with a Davis Weather Station instrument set.
The CS3-Terraduino Weather Station. Data is taken every 2 minutes and relayed back to a CS3 gateway and on to a webserver with a database where the data is immediately available for viewing via the internet with your favorite smart phone, tablet or PC. Here the Terraduino is shown with the industry standard Davis Weather station instrument package that it supports. The Terraduino enclosure cover is shown removed to show the internal electronics and rechargeable batteries.
The gateway, shown below is a cost effective Linux computer originally designed for use in smart phones and tablets. It has HDMI graphics output and 2 USB ports for keyboard, and mouse connections enabling its use as a desktop PC but, it usually ends up on a window sill somewhere near your internet router. It automatically reboots itself after power failures and internet outages.
The user interface of the CS3 system is served by Camalie Networks Servers in Palo Alto, 5 blocks from the internet's main west coast hub where Google and Facebook started up.
Here's an example map page for a vineyard in Napa near St. Helena. It shows where the nodes are located in the vineyard which is essential in interpreting the data.
Here's a dashboard of graphs from another vineyard. It includes tank water level, Temp, Humidity, Wind speed, Rain and soil moisture.
Below on an iphone you can see soil Moisture data at three different depths for 6 different irrigation blocks in a 50 acre vineyard over a period of one month. The falling transients in the curves are irrigation events. The CS3 system is designed to enable viewing of data as fast as possible. Your time is valuable and if you don't look at the data its useless. This page painted in 2 seconds which includes the time it took to pull all of the data from the database. CS3 uses a very high performance linear database and a highly optimized open source grapher developed and used by high energy particle physicists at the Swiss Federal Institute over the last 15 years. It is extremely robust. No Microsoft/Apple/Google/Oracle/Adobe/Facebook code is used and as a result the software almost never needs updating.
Below is an example of the valve control interface for one vineyard. Note this code runs on an iPhone because it does not use Adobe Flash. It also runs under any browser. It is not a specific Apple or Android mobile phone app which might be prettier but, would require updates and new downloads to your phone every time the phone O.S. gets updated. We consider any time spent keeping a CS3 system up and running is wasted time.
* Note all Field stations above use the XBee 900MHz Digimesh long range, solar powered wireless network.
**CS3 is a high value Wireless Sensor Network (WSN) and Internet of Things (IOT) Application.
