  1. Water and Wastewater Focus Wireless Sales Push 2009

  2. 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?

  3. 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?

  4. 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?

  5. 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?

  6. Irrigation Water and Wastewater Program 2009

  7. Irrigation Outline • Background Info & Terminology • Main Irrigation Types • Level Sensing/Soil Moisture • Switch/Valve Actuation • Flow Meter/Pressure

  8. 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

  9. 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

  10. 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 Surface Irrigation Level Sensing

  11. Surface Irrigation for Cranberry Farm

  12. Surface Irrigation for Cranberry Farm

  13. Surface Irrigation for Cranberry Farm • 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

  14. 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

  15. Localized Irrigation Vault / Flow Meter Antenna cover Vault cover Siemens Mag Flow meter. Will be coupled to DX80 Counter Node

  16. Localized Irrigation Vault / Flow Meter

  17. 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

  18. Localized Drip Irrigation Node placement Pump Control 1.6 km between Pump Control and Section B Section B node Section A

  19. Localized Drip Irrigation Final Geometry Pump Control & Data Radio node Gateway & Data radio

  20. Valve/Switch Control Use Node discrete outputs Localized Irrigation Other Applications

  21. Soil Moisture Monitoring Localized Irrigation Other Applications

  22. Used in large scale agricultural operations Two main types of sprinklers Pivot Lateral Sprinkler Irrigation

  23. Flow Meter Pressure Monitor Sprinkler Position Control Soil Moisture These applications ensure consistent watering Sprinkler Irrigation Applications

  24. 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

  25. 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
