Review

Week 1 – Program Introduction

– Water and wastewater is a high sales potential market

– Important to contact all parties involved in the project

– Have you identified: End users? Associations? Tradeshows? Process distributors? Engineering companies?

Review

Week 2 – Composting

– Convert organic and bio-solid waste to compost

– Key application: windrow temperature monitoring

– Other applications: flare stack, oxygen, acidity, and moisture monitoring

– Did you: Study the DX80

temperature node? Find a local

compost facility? Identify technology

used at this facility?

Review

Week 3 – Landfill

– Area where waste is buried to decompose

– Methane gas and leachate water generated

– Did you:

Read App Notes 146127 and 146128?

Read Counter Node datasheet 136348?

Locate your landfill?

Review

Week 4 – Sewage Treatment

– Where toilet waste is processed

– Methane gas and compost are generated

– Did you: Study Temp and Humidity

Sensor (137303, B_032362)?

Read Serial Node datasheet 136971?

Locate your sewage plant?

Irrigation

Water and Wastewater Program 2009

Irrigation Outline

Background Info & Terminology

– Main Irrigation Types

Level Sensing/Soil Moisture

Switch/Valve Actuation

Flow Meter/Pressure

Key Terms and Background Info

Irrigation is the application of water to assist in growing crops in dry areas and during periods of inadequate rainfall

Irrigation is also used to protect plants from frost, prevent weed growth in rice fields and to prevent soil compaction

Irrigation Types

– Surface Irrigation

– Localized Irrigation

– Sprinkler Irrigation

Irrigation Types

Surface Irrigation is a system where water moves over and across the land by the use of simple gravity in furrows, border strips, or basins

Localized Irrigation is a system where water is distributed through a pipe network and applied as a small drip or discharge near each plant

Sprinkler Irrigation is a system where water is piped to one or more locations in a field and distributed through high-pressure sprinklers or sprayers

Irrigation District controls the flow volume in channels based on daily demand of water

Ultrasonic sensor utilized to measure water level

– Sensor provides a 4 – 20 mA signal at Node

Information transmitted to control room

– Gateway output provides 4 – 20 mA signal

– Digital panel meter displays scaled flow volume

– Operator manually turns pumps On/Off as required to maintain correct water level

Moisture Sensors are used to monitor the soil moisture (SDI-12 Irrigation Standard)

Banner offers a number of FlexPower Nodes to work with the SDI-12 standard (contact Banner)

This information is used to help determine the correct level of water in the border strips

Localized Irrigation System in Orchard

The orchard uses a drip irrigation system and has 200 vaults

Each vault has a Siemens Mag flow meter

– Each flow meter will need a DX80 Counter Node

– 4 DX80 Gateways for wireless network

– Gateways mounted in a truck that drives through orchard

Totalized outputs from the DX80 Counter Node determine water consumption

– Data will be written to a flash drive as the truck tours the orchard

Localized Irrigation Vault / Flow Meter

coupled to DX80 Counter Node

Localized Irrigation Challenges

Irrigation systems can cover large areas of 2-3 km or more

Must transmit signals over hills

– Requires antenna extensions

– Requires correct network geometry Use Data Radios for range extension Many of these locations do not have

power available

– These applications require battery and solar power solutions

Localized Irrigation Other Applications

Soil Moisture Monitoring

Localized Irrigation Other Applications

Used in large scale agricultural operations

Two main types of sprinklers

– Pivot

– Lateral

Sprinkler Irrigation

Flow Meter

Pressure Monitor

Sprinkler Position Control

Soil Moisture

These applications ensure consistent watering

Sprinkler Irrigation Applications

Solar Power for Irrigation Due to the large scale of many irrigation systems,

power is not always available

Banner Solar Panel BWA-SOLAR-001 can provide the power required

– Nodes available for continuous power

Other Solar Power systems can also be used

Homework Week 5

Identify 2 locations that use irrigation systems

Identify the engineering companies that design/operate/maintain the irrigation systems

Study/Review the DX80 Data Radio data sheet, P/N: 132031

Study/Review the BWA-SOLAR-001 data sheet, P/N: 137304

Study/Review the SureCross Wireless Network Brochure, P/N: 131620
