SOLAR INSTALLATION

For better installation and easier setting up, please

download the user manual for WMR300/WMR300A

from the below link:

http://weather.oregonscientiﬁc.com/products_wmr300.asp

To properly install your sensor, you may need some

tools -- including screwdrivers, wrenches and an

electric drill. What you need will depend on how you

mount your sensor.

The transmitter box is capable of transmitting data

wirelessly an approximate operating range of 300m

(984 feet). Ideal placements for the sensor would be in

any location on the roof of a building that is in an open

area away from trees or other obstructions that may

prevent an accurate reading. Also, be sure to locate

the transmitter box in direct sunlight for optimal power

supply from the solar panel.

Solar panel facing: If you reside in the:

North Southern Hemisphere

South Northern Hemisphere

NOTE

Make sure the

thermometer & humidity sensor

is located at least 1.5 meters

above the ground surface to

avoid the ground temperature

affecting accuracy of the

thermometer & humidity sensor.

SET UP TRANSMITTER BOX

The transmitter box can wirelessly transmit data to

the main unit.

Option 1: Install the transmitter box on a pole

1.5MM

Ground

1. Prepare a pole, a plastic mount bracket and a U-bolt

without ﬂat washers, lock washers and hex nuts

(ﬁgure 1).

2. Position the pole inside the U-bolt and securely

tighten the mount bracket on the pole with the U-bolt

by the four pairs of the ﬂat washers, lock washers

and hex nuts (ﬁgure 2). Use wrench if necessary.

NOTE

Make sure the engraved arrow UP on the mount

bracket is positioned correctly.

3. Insert the extended tabs of the mount bracket into

the slots on the back of the transmitter box. Push

the transmitter box down until it is securely in place

(ﬁgure 3 & 4).

NOTE

Locate the transmitter box in direct sunlight for

optimal power supply to the solar panel (see Sensor

Installation section).

Option 2: Install the transmitter box on a

wooden board

1. Prepare a wooden board, a plastic mount bracket

and four pairs of Type A screws without flat

washers and lock washers (see above ﬁgure 1).

2. Position the mount bracket on the wooden board by

securely tightening the Type A screws using some

tools (see above ﬁgure 2).

NOTE

Make sure the engraved arrow UP on the mount

bracket is positioned correctly.

3. Insert the extended tabs of the mount bracket into

the slots on the back of the transmitter box. Push

the transmitter box down until it is securely in place

(see above ﬁgure 3 & 4).

NOTE

Locate the transmitter box in direct sunlight for

optimal power supply to the solar panel (see Sensor

Installation section).

SET UP THERMO & HYGRO SENSOR

The thermo & hygro sensor takes outdoor temperature

and humidity readings. Before positioning the sensor,

install the sensor onto a metal mount bracket.

• Securely tighten the sensor on the metal mount

bracket by Type B screws with lock washers and

ﬂat washers. Use wrench if necessary (ﬁgure 7).

Option 1: Install the sensor on a pole

1. Prepare a pole and a U-bolt without ﬂat washers,

lock washers and hex nuts. Position the pole inside

the U-bolt (ﬁgure 8).

2. Securely tighten the metal mount bracket on the

pole with the U-bolt by the four pairs of the ﬂat

washers, lock washers and hex nuts (ﬁgure 9).

3. Securely locate the pole in your desired outdoor area.

Option 2: Install the sensor on a wooden board

1. Prepare a wooden board, a metal mount bracket

with the sensor installed and four pairs of Type

A screws without ﬂat washers and lock washers

(ﬁgure 10).

2. Position the metal mount bracket on the wooden

board by securely tightening the Type A screws

using some tools (ﬁgure 11).

3. Securely locate the wooden board in your desired

outdoor area.

CABLE CONNECTIONS

Please connect the cable of the thermometer &

humidity sensor to the transmitter box before positioning

the pole or wooden board.

1. Unscrew to open the

transmitter box.

2. Take off the rubber

stopper from the

cable slot.

3. Insert the sensor

cable through the

cable slot.

4. Plug the thermometer

& humidity sensor

cable into TH socket

that has name below

the socket for

recognition. A click

sound can be heard.

5. Return the rubber stopper to the cable slot.

NOTE

Route the excessive cable neatly if necessary.

TRANSMITTER BOX-

BATTERY INSTALLATION

The solar panel on the transmitter box is an

energy-saving feature, designed to provide power

to the sensors to prolong battery life and reduce

environmental impact. The sensor should be able to

operate entirely on the rechargeable battery power.

Place the transmitter box in direct sunlight for optimal

power supply to the panel.

The rechargeable battery that is charged by the solar

panel likely has diminished power by the time you set

up your sensor. We recommend that you charge it for

several hours using the connected solar panel before

using the sensor.

RAIN

SOLAR

UVTHWIND

RAINTHWIND

SOLAR

You can also purchase a power adapter separately for

directly providing power to the

transmitter box. The output

voltage of the power adapter

is 3V. Route the adapter cable

through the cable slot.

Please check the solar

panel connection. If it is

not ﬁrmly plugged, please

re-connect the solar panel:

Plug the end of the color-corded connector into the

corresponding socket in the transmitter box as shown

below and place the wires neatly inside the box.

To install the rechargeable battery:

Insert the battery into the battery compartment,

matching the polarity +/-.

CHANNEL SETTING

Your weather station

system (WMR300) can

expand to up to 8 sets of

thermometer & humidity

sensors (THGN301), and

one of each of wind and

rain sensors (WGR300 or

PCR300), all of which display their information on one

main unit. You can number each transmitter box with an

independent channel ID (1-8) by sliding the switches.

Please follow the below chart to adjust the sliding

switches of SW1:

NOTE

The below 0 in the chart represents off and 1

represents on.

After setting, please turn off the LED light by sliding the

PIN 1 switch to 0 to save power, and then close the box

by tightening the screws.

NOTE

The flashing LED indicates a normal

transmission (See LED Light Indicator section).

REMOVE SETTING

To remove the previous setting from the transmitter

box, you can press RESET and KEY at the same

time, then only release RESET, red light ﬂashes 5

times. Then release KEY. The channel setting and

calibrated wind direction are then all removed from

the transmitter box.

MAINTAINANCE

Each sensor in this

pack has a durable

plastic casing that

should retain its luster

for many years. For

best results, clean your

sensor every 6 months

to ensure optimal

accuracy. Clean the

casing only with a soft

cloth slightly dampened with water or a mild soap.

Please use screw drivers or a wrench to take some

parts off if necessary.

Electrical storms can sometimes cause power

surges harmful to electronic equipment. For your own

safety, take caution when using the main unit or doing

maintenance during storms.

TO MAINTAIN THE THERMO/HYGRO SENSOR

1. Unscrew the three screws from the bottom of the

thermo/hygro

sensor casing.

2. Clean the casing

excluding the one

with sensor by

water, and then

remove the dust

around the

sensor carefully.

3. Install all the parts

until they are entirely dried.

NOTE

If the temperature and humidity readings are

still strange and inaccurate, you need to consider

replacing this sensor. Please contact our customer

service for details.
