1 Introduction

1.1 The MEP-SYS410 Mote Environment Monitoring System

This quick start guide will help you get your MEP-SYS410 environment monitoring systemdeployed and running. The sensor nodes (MEP410 and MEP510) and base station (MBR410) are

ready to be deployed right out of the box. This system can be used for a variety of applications

including Environmental/Agricultural Monitoring and Analysis and Equipment Diagnostics.

The MEP-SYS410 system has two types of sensor nodes: MEP410 and the MEP510. Each nodeis preprogrammed with a sensing application that communicates and transmits data back to the

base station through a multihop mesh networking.

The MICA mote technology is embedded in the module and runs anXMesh-enabled sensing

application.XMesh is a flexible, proven ad-hoc mesh networking protocol stack developed byCrossbow. CrossbowsXMesh software algorithms provide the user with easy installation at

multiple monitoring points while avoiding the need for wired repeater nodes.

You can useMoteView to visualize data from your network of sensor nodes. The installation ofMoteView onto a Windows

PC is described in Chapter 2.

1.2 Package Contents

The contents of the MEP-SYS410 system include the following items (see the photo in Figure

1-1 which shows the contents as provided in the MES-SYS410 shipping box).

Two MEP410 sensor nodes with external battery packs

Four MEP510 sensor nodes

One MBR410 base station

One CD withMoteView: This software allows you to immediately view the sensornetwork on a PC running Microsoft Windows.

OneMEP-SYS Users Manual: This contains valuable information including gettingstarted, hardware overview and deployment tips.

2 Quick Start for the MEP-SYS Users

IMPORTANT: This section is intended for the MEP-SYS Kit users only. If you did notpurchase the complete kit, but only stand-alone nodes then skip to Chapter 3.

2.1 Out-of-the-Box Demo

This section will step you through the process of setting up a simple MEP-SYS sensor networkdemonstration. The three main steps are to

1. Install MoteView on your Windows PC

2. Set up MEP sensor nodes along with the MBR base station

3. StartMoteView and log sensor data from the wireless network

2.1.1 Installing MoteView on a Windows PC

Before you can useMoteView you have to install it on a PC. The requirements necessary to

properly installMoteView are below:

1. A PC with one of the following operating systems

Windows XP Home/Professional

Windows 2000 with SP4

2. An NTFS file system

3. Screen resolution must be at least 800 600 or the interface will require scrollbars

4. Administrative privileges to write to Windows registry

NOTE: Prior to installingMoteView, it is highly recommended that you shut down all theprograms running on your computer.

Follow these installation steps:

1. Insert theMoteWorks Support Tools CDROM into the computers CD drive.

2. Double-click on MoteView_Setup.exe from MoteView folder.

3. Select the desired installation directory (the default installation directory is C:\ProgramFiles\Crossbow\MoteView)

4. Select all available installation tasks

5. InstallShield will guide you through the rest of the process and install the following:

MoteView application

PostgreSQL 8.0 database service

PostgreSQL ODBC driver

Microsoft .NET framework

NOTE: If you receive an MDAC warning due to Windows incompatibility issue, you mayignore this by clicking Cancel and continue with the installation.

3 Product Overview

3.1 The MEP410 Sensor Node

The MEP410 sensor node is a multi-sensor platform. It has sensor ports on the top and bottom

faces of the enclosure. Table 3-1 below lists the main features of the MEP410.

Table 3-1. The main features of the MEP410 sensor node.

Main Hardware Features Photo

MICA Mote technology running an XMesh-enabledsensing application.

Environment monitoring sensor suite

Two total solar radiation sensors

Two photosynthetic radiation sensors.

Digital external and internal relative humidity withintegrated temperature sensor

Digital barometric pressure with integrated temperaturesensor.

A heat reflective, water resistant plastic box with sensorwindows and ports and mounting holes.

Internal LEDs for use as status indicators.

External, wave 433 MHz antenna.

External battery pack with two alkaline C, 1.5 V cells andrugged, 6 cable.

Dimensions: 3.5 3.5 2.4, not including antenna andexternal connector.

3.2 The MEP510 Sensor Node

The MEP510 is a sensor node with an integrated digital relative humidity and temperature

sensor. It can be mounted to other objects by using the flange mounts on the enclosure. Poweringthe unit is accomplished by sliding the on-off switch to the on position.

External, wave 433 MHz antenna.

Dimensions: 3.5 3.5 2.4, not including antenna.

3.3 MBR410 Base Station

The MBR410 base station package provides a serial interface to a PC and a radio to

communicate with MEP410 and MEP510 units. The base station is programmed with thereserved node ID of 0 (zero) so that the data from the remote MEPs will route to it.

The MBR410 forwards the sensor network data to a PC as well as other standard computer

platforms through a RS-232 interface. This serial interface is a standard single channel bi-

directional interface with a DB9 connector. A DB9 (male) to DB9 (female) straight throughcable is provided to connect to a 9-pin serial port.

Powering the MBR410 is accomplished by connecting the plug from the provided AC-DC wall

power converter to the MBR410s 5 VDC jack. The AC-DC wall power adaptor outputs 5 VDC

when connected to wall power. There is no on-off switch for the MBR410. Turning off thepower to it is accomplished by removing the plug.

4 MEP-SYS410 Deployment Overview

4.1 Important Considerations during Deployment

In a typical application, the sensor nodes of MEP-SYS410 system are deployed at locations ofinterest either on the ground or elevated. Multiple MEP-SYS410 nodes automatically

communicate with each other and form a reliable low-power communications network. Once

detection occurs it is forwarded across the network to the base station.

The placement and relative orientation plays an important role for the MSP410s to collectivelywork together to detect an event. Some important considerations are:

Issue Effect

Height of the sensor node off the ground The RF signal on the ground will travel about 1/10th

the distancecompared to a node placed about 3 feet off the ground

Physical environment, such as foliage,structures, objects

The more dense and cluttered the environment, the greater theattenuation of the RF signal. The rate of attenuation greatly varies withdifferent environments.

Antenna orientation Ideally all of the sensors are placed such that the antennas are verticalwith respect to the ground/floor.

4.2 Battery Replacement

The MEP410 node powered using an external battery pack which houses 2 standard alkaline C

cells (1.5V each), typically lasts for about 2 years. These batteries can be replaced by removing 4screws holding the lid found on the battery pack. After replacing the batteries, tighten the screwsto ensure water-resistance.

The MEP510 node powered using an internal Lithium 2/3A battery (CR123A, 3V), typically

lasts for about 6 months. This battery can be replaced by removing 4 screws holding the lidfound on the module. After replacing the batteries, tighten the screws to ensure water-resistance.

4.3 Adding more MEP sensor nodes to the network

The MEP sensor nodes are pre-programmed at the factory to runXMesh-based sensorapplication. You can easily add more MEP nodes to your network by simply turning them ON

(or by connecting them to the battery packs). The following are the default factory parameters.
