- 6 - HOBOnode Wireless System Chapter One: About the HOBOnode System Overview The HOBOnode wireless sensors are easy to deploy and move. There are no cables to run through crops or building walls, you are not limited by cable length limits, and there is less chance for loosing measurements from cable damage. Benefits • Solar recharging - can run for multiple years without having to replace batteries • Real-time graphs • Alarms sent to your e-mail account • Data can be exported for use in other programs. • Repeaters allow communication to sensors that are miles away • Research-grade reliability and accuracy • Small size makes them especially easy to deploy • Operating range Uses The HOBOnode wireless system is ideal for: • Crop and Irrigation Management • Ag Research • Ecology • Greenhouse Management • Building Management (outside temperature) • Landscape Management Standards The HOBOnode Wireless System uses the IEEE 802.15.4 wireless data standard, in the 2.4 GHz ISM band, which is approved for worldwide use. Components The following components make up a HOBOnode Wireless System: • W-TMB HOBOnode wireless temperature sensor • W-SMC HOBOnode wireless soil moisture sensor • W- RCVR-USB HOBOnode Receiver • W-REPEATER HOBOnode Repeater (Optional) • HOBOnode Viewer software – free download

- 7 - HOBOnode Wireless System Battery Options The HOBOnodes and HOBOnode Repeaters are shipped with re-chargeable Alkaline batteries. You can also use Onset-supplied Lithium batteries for increased operating temperature range (-40 C). Accessories • Lithium AAA - 2-pack (Part# HRB-LI-AAA) • USB active extension cable – 16’ (Part# CABLE-USB-EXT) • USB Extension Cable • 2-meter Tri-pod • Replacement Batteries • Guy Wire Kit

- 8 - HOBOnode Wireless System Theory of Operation Standard The radio technology used for the HOBOnode Wireless System is a 802.15.4 radio running in the 2.4Ghz spectrum. This is an ISM band technology and is legal to use in almost all countries. The underlying communications protocol running on this radio technology is Onset proprietary. This choice was made to both maximize battery life and minimize cost. Communications Protocol The HOBOnode Wireless System uses a time slot based communications protocol. The system views time in 1/4 second per time slot with 1 minute before the timeslots repeat. All HOBOnodes measure at the same timeslot, so even though your data reports arrive when the device’s timeslot is active, the measurement time for all devices is common. Network ID Because it is possible to have more than on HOBOnode Network running in the same area it is important that unique network IDs are assigned so that the networks can co-exist peacefully. A unique network ID consists of two elements. The first element is an RF channel; the second is a Unique ID (any number from 0 to 4095). If two HOBOnode Networks are being configured, it is best to select different channels for them to use. Although they can share a channel, there is a potential for interference. New HOBOnodes and HOBOnode Repeaters come from the factory with a blank network ID. Once a device is linked to a HOBOnode Receiver it will only respond to that HOBOnode Receiver. The network ID can be cleared from a device if you need to change it. Packets In the simplest exchange, a HOBOnode is connected directly to a HOBOnode Receiver. In this case, the HOBOnode will send a packet of up to 128 bytes to the Receiver. The HOBOnode Receiver receives and verifies the packets validity (unique network ID, CRC et.), sends a Reply packet to the device, and forwards the packet to HOBOnode Viewer (host software). This is made slightly more complicated by having a HOBOnode Repeater or a line of HOBOnode Repeaters between a HOBOnode and the Receiver. It is essentially the same operation as above except it is repeated on each hop. You can only chain HOBOnode Repeaters to a depth of 4 hops. This is because there is only 1/4 second to get the packet and reply done between all the devices in the chain. For reliability purposes, packet/ reply exchanges are retried between nodes. Lost Node A device becomes lost when it has not had a successful packet/reply exchange 4 times in a row. By default, the HOBOnode Receiver will automatically search for lost nodes every 4 minutes.

- 9 - HOBOnode Wireless System Sending Commands Commands sent to devices must be carried in the reply packet generated in the packet/reply exchange. This means a command can only move down 1 hop in the network each minute. So, a command to a device that is 4 hops down in the network may take up to 4 minutes to reach the device. The main commands are Start Manual Search, Stop Manual Search and Auto Search. Maximum Endpoints There is a limit of 50 endpoints (HOBOnodes plus HOBOnode Repeaters) per system. This is to preserve the battery life of the HOBOnode Repeaters. Many wireless systems suffer from having to have repeaters on wall power. The Onset system does not require this due to reasonable system limitations coupled with a design that took battery life into account.

- 41 - HOBOnode Wireless System Chapter Seven: Maintenance De-activating a HOBOnode If you will not being using a node for an extended period of time you may want to deactivate it to save the battery. To deactivate a node, hold down the Set/Clear button for 5 seconds until the red LED flashes quickly and then stops. This places the node in RF Off mode and it cannot be found by a HOBOnode Receiver. To re-activate the node, hold down the Set/Clear button for 2 seconds (see Activating a HOBOnode). Moving a HOBOnode If you move a HOBOnode to a new location, you may need to re-link it to the HOBOnode Receiver or a HOBOnode Repeater if it is moved out of range or Line of Sight. After you move the HOBOnode, check the Network Tree in HOBOnode Viewer and see if it is still linked. If it is not linked, there are two options: • AutoSearch for Lost Node If you have AutoSearch on Lost Node enabled, the network will automatically reconnect to the node if it is within range of a HOBOnode Receiver or HOBOnode Repeater. The HOBO Receiver auto searches every hour for lost nodes. If it does not find any within 4 minutes, the first HOBOnode Repeater in the hierarchy will search for 4 minutes. This will continue with all HOBOnode Repeaters until the HOBOnode is found. • Manual Search If you have moved a HOBOnode and you want it to link to a specific HOBOnode Receiver or HOBOnode Repeater, right-click on the devices icon in HOBOnode Viewer and select Send Command > Start Manual Search.

- 54 - HOBOnode Wireless System Chapter Eleven: Compliance FCC Part 15 Compliance The following information applies to the HOBOnode Receiver. FCC Compliance This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. Changes or modifications not expressly approved by Onset Computer Corporation could void the user's authority to operate the equipment. To comply with FCC and Industry Canada RF radiation exposure limits for general population, the HOBOnode Receiver and the HOBOnode Repeaters must be installed to provide a separation distance of at least 20cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Canada This device has been designed to operate with the antennas listed below, and having a maximum gain of [x] dB. Antennas not included in this list or having a gain greater than [x] dB are strictly prohibited for use with this device. The required antenna impedance is [y] ohms. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. FCC Declaration of Conformity 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.
