Feldman Consulting Enterprises,
LLC can help you take advantage of the possibilities of
wireless communication with Arduino, including data collection, monitoring,
and remote control.
Wireless Data Collection and
We can design and
implement systems based on Arduino and Xbee for data
from large areas, such as an entire facility or a large
field. You can use this data to monitor your own operations
in real-time, track historical trends, or even aggregate
data from your customers and provide it back to them. The Xbee wireless transmitters have ranges from several hundred
feet indoors to several miles in line-of-sight conditions
outdoors with appropriate antennas, which allow for
construction of incredibly large mesh networks and SCADA
Your information can be
sent to secure databases on the Internet through a standard
Internet connection, or through a cellular connection for
more remote or difficult locations. The data can be bundled
from multiple sources and sent through one connection to the
Internet, reducing your infrastructure and communication
costs. We have designed sensors that provide real-time data
where power is available, and also have designed low power sensors
that send data once every few hours but can run for 3 years
without requiring a battery replacement. Our sensors are
designed to be tough enough for outdoor use with
industry-standard NEMA boxes and have proven themselves in
temperatures as low as 0F / -18C, as high as 100F / 38C, rain storms, and snow
- The Arduino can be connected to the Internet over
802.11 b/g/n using the same routers and access points that
are set up for computers, laptops, and mobile phones.
- By using Xbee 802.15.4 technology, a large mesh network
can be set up so that data can be passed along from node to
node to reach its destination, which can then be transmitted
to the Internet through a base station with a wired, wifi,
or cellular Internet connection. The ability to hop from
node to node allows for data to be transmitted over a much
longer distance than regular wifi. There are also lower
frequency 900 MHz Xbee transmitters for going greater
distances. And Xbee communication is specifically designed
to allow for low power designs that go into sleep mode, wake
up when necessary, send data quickly, and then return to
sleep mode to conserve power.
This is a
typical prototype sensor that uses an Xbee wireless module

Wireless Remote Control
Do you have devices in
far-away locations that need to be automatically monitored
and controlled with the possibility of manual override? Save
yourself the time and effort of traveling to each location
to check up on things by having an Arduino do it for you
over a wireless connection!
Some examples of the possibilities include:
|Tank telemetry -
Do you make deliveries to refill tanks for clients,
such as heating oil or propane? With tank telemetry
you would always know exactly how full every tank
is, preventing your customers from running out of
product and saving you money on servicing.
- Do you need to measure parameters like temperature
and humidity? Or water depth or flow? Are you
considering a traditional SCADA system? For agricultural purposes being able
to sense conditions and control your irrigation and
fertilization can greatly improve your yield.
- You could automatically monitor the temperature,
doors, and lights in every room in your facility to
save energy and money using Arduino instead of a
traditional SCADA system or PLC.
|Automatic dispensing and
monitoring - Do you need to monitor and
dispense controlled amounts of products like
chlorine in a pool or chemicals in a lagoon to
maintain process control?
|Compliance - Are
you required to monitor things on regular intervals
for compliance purposes, such as the temperature of
refrigerators, condition of equipment, or air and
water quality? An automated solution will free you
from the effort and risks associated with manual
logging and help you identify issues sooner.
- Do you know where your assets are in your
warehouse? You could track them with RFID so that
you'd always know where they are, or for assets that
go outside of your facility, track them with GPS.
Here's how we've helped other
clients harness the power of Arduino Wireless Networks. You could be next!
Case One -
Sewage System Monitoring
A county housing authority
needed to monitor the functionality of their sewage holding
tanks and pumps. The county had experienced issues in the
past with their systems malfunctioning, which resulted in
sewage overflowing from holding tanks. This was, of course,
a very messy situation which resulted in complaints, costs
for cleanup, and the potential for fines from the EPA.
Enterprises, LLC set up systems to monitor the pumps with
current clamps and sewage levels with ultrasonic sensors at
two of the housing authority's sewage tanks. The readings
were transmitted by the sensing unit every 15 minutes to an online
database over a cellular Internet connection. The database
allowed for the authority to be alerted by email very
quickly when problems were detected and to resolve issues
while they were still minor before they had become major
disasters. The monitoring system also helped detect several
other anomalies, some of which were the result of errors
made during the initial setup of the sewage tanks years
prior and had gone undetected ever since.
Live updates of sewage
tank levels and pump current every 15 minutes
Pump and switch
malfunctions, control system wiring issues, and clogs
were detected through pump current monitoring
monitoring allowed the authority to respond to
abnormally high tank levels before tanks overflowed
helped detect problems with pumps before pumps
completely failed, reducing the need for emergency
sensors measure the sewage level while current clamps
monitor pump current. All the data is transmitted to an
online database for easy monitoring at a glance.
Case Two - Stream
depth and flow measurement using eTape™
A local municipality
needed to monitor the depth and flow rate of a stream at a
remote location to ensure that enough water was being
released from their reservoir into a nearby lake. By
precisely measuring the depth of the stream the flow rate
through a V-weir could be calculated.
Enterprises, LLC set up a battery-powered remote sensing module using
an Arduino and a
brand new patented technology called eTape™ from
This allowed us to measure the depth of the stream to within
1mm (1/25th of an inch). The readings were transmitted by
the sensing unit every 15 minutes several hundred feet
wirelessly via Xbee to the
nearest available location with power where a cellular base
station could be installed to send the reading to an online

Case Three - Monitoring water pressure
and flow from traditional 4-20mA sensors
A local municipality was
monitoring the water flow rate and pressure through several
different lines at a switching station. This installation
was using traditional PLC and SCADA equipment to monitor
industry-standard 4-20mA sensors that had been in use for
quite some time. The goal was to read these sensors using
Arduino-based technology to determine the feasibility of
replacing the traditional PLC equipment with Arduino-based
technology with a printed circuit board that was no bigger than a typical slice of pizza.
Enterprises, LLC designed a custom printed circuit board
that would simultaneously measure current from up to 16
sensors plus 7 analog signals and 3 digital signals. Since
this installation had power available the data was sent directly
over Ethernet to a cellular base station for insertion into
an online database.
Traditional PLC and
measurement functionality matched much more
cost-effectively with a printed circuit board based on
the Arduino Pro Mini
No need to replace
existing calibrated industry-standard 4-20mA sensors,
making retrofits easy
would make future ground-up installations much easier
This is the
original PLC cabinet with all the traditional equipment.

screenshot of live data obtained with the Arduino board.
Case Four - Monitoring water level at
a reservoir - our biggest dam project yet!
A local municipality
monitors the water level at their reservoirs to determine
the amount of water available and to ensure the safety of
their dam. Over time the water level might vary by as much
as 30 feet. These reservoirs are often in remote locations.
Enterprises, LLC set up two ultrasonic sensors to measure
the water level in one of the reservoirs at 15-minute
intervals. The readings were transmitted by the sensing
units every 15 minutes wirelessly via Xbee to a cellular base
station, which transmitted the readings to an online
database. The ultrasonic sensing units were about the same
size as a typical coffee mug and much less complex to
operate and install than the traditional vibrating wire
piezometers that are often used with a SCADA system to measure water depth.

Case Five - Monitoring pressure at a
PCB production facility
A Fortune 500 company
involved in making printed circuit boards for aerospace and
defense applications needed to measure pressures and other
parameters at various points on their lines throughout the
Enterprises, LLC designed Arduino-based monitoring boards to
measure many different parameters and display the values in
real-time to operators on a screen. In addition, these
values were transmitted to several base stations throughout
the plant, which connected to an internal database over WiFi
to log the data that was collected.
Vastly reduced the
amount of wiring necessary for data collection
Monitoring boards were
designed to allow for interfacing with multiple sensor
types for future expansion
