USER MANUAL ™ EnviroMonitor ® R Sensor Node Product number 6810 R Davis Instruments, 3465 Diablo Avenue, Hayward, CA 94545-2778 U.S.A. • 510-732-9229 • www.davisnet.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.
Welcome to EnviroMonitor Sensor Node An EnviroMonitor System includes a Gateway and a number of Nodes that house up to four sensors each. The Nodes transmit the sensor data to the Gateway, either directly from Node to Gateway, or indirectly by “hopping” from Node to Node to Gateway via mesh network operating at 900 MHz (different in the EU). The Gateway then sends the data via cellular connection to the Cloud. EnviroMonitor can be customized for any size installation.
Plan Installation of Nodes Before installation, plan your system. After determining which sensors you want and where you want to install them, make sure you have the correct number of Nodes to support those sensors. The maximum distance between Nodes and Gateway will be different for installation depending on many factors, but in ideal conditions may be up to 2,000 feet (600 meters).
Siting the Nodes • Make sure each Node is sited so that it has at least two ways to reach the Gateway. It should be within transmission distance (up to 2,000 feet/600 meters) of either two other Nodes, or the Gateway and another Node. This allows the mesh to “heal” any temporarily impaired transmission paths and will ensure data reaches the Gateway. You can have any number of hops from Node to Node.
Installing the Nodes and Sensors Contents of Node package Rechargable Lithium Battery (included) Solar Panel Cable D-Cell Battery Compartments (batteries not included) Sensor Junctions Antenna Hardware Kit U-Bolts 1/4" Lock Washers 1/4" x 1 1/4" Lag Screws 1/4" Hex Nuts Backing Plates 6-Wire Sensor Connectors 4 #6 x 3/8 Screws (not needed)
Requirements & Tools for Installation of Nodes and Sensors • Node with at least one sensor • Small flathead screwdriver • 4 D-cell batteries • Smartphone with Setup app installed • Wire cutter/stripper • Mounting pole or post • Wrench • Screwdriver if mounting to a post Note: You should install Nodes from closest to Gateway to furthest from Gateway so that each Node can establish a connection with the Gateway or a Node that has already been installed.
example, if you plan to mount the node on a tower, you will want to install the sensor first. 1. Install the sensor in the into the sensing medium per the manufacturer’s instructions and the needs of the environment, making sure the sensor is installed within cable reach of the Node. 2. Wire the sensor into one of the 6-wire sensor connectors. Each sensor has specific wiring specifications. In the app, find the sensor on the Sensor Junction Wiring Diagram to determine how it should be wired to the junction.
7. When all sensors are installed, close the shelter door, making sure all cables are against the foam and not the hard plastic of the door. Mount the Node Shelter The Node shelter can be mounted on a pole or a flat surface such as a wall or a wooden post. It is important that the shelter be mounted so that the solar panel gets the greatest amount of sunshine -- the solar shelter should be facing south (in the northern hemisphere) or north (in the southern hemisphere).
Mounting on a Flat Surface Attach the shelter to the mounting surface in the desired location using the lag screws and backing plates as shown below. Use a pencil or a center-punch to mark the location of the pilot hole. ® Mounting On a Pole Mount the Gateway onto a pole with an outside diameter of 0.84'' to 1.84'' (21 mm to 27 mm) using the U-bolts, backing plates, washers, and hex nuts provided.
Troubleshooting How can I tell if my battery voltage is getting too low? Our server will monitor your battery voltage and will trigger an e-mail warning if it should get critically low (approximately 14 days of power). The e-mail will go to both the registered customer’s e-mail address as well as the alarm e-mail address (if one has been set up). My installation is in a low light area. Can I add another solar panel? Yes. You can add an Extra Solar Panel Kit (product number 6616).
