Oregon Scientific WMR100N
Professional Wireless Weather Station

The Oregon Scientific WMR100N Professional Wireless Weather Station is an advanced, yet cost effective weather station. The Oregon Scientific Weather Station measures indoor and outdoor temperature and humidity, wind speed and direction, barometric pressure, and rainfall with the included sensors. Calculated values include forecast, dew point, wind chill and heat index. Remote temperature and humidity from up to 9 additional remote locations, and UV light intensity may be measured with optional sensors (not included). All remote sensors are totally wireless with a range of up to 300 feet.

The Oregon Scientific WMR100N home weather station console stands about 6 1/2 inches high, and is finished in silver and titanium gray. All commonly used functions are controlled by the black rotary dial.

The WMR100N has five display areas. The first area, the forecast area, displays one of five icons representing the likely weather for the next 12 to 24 hours.

The second display area can display current, minimum and maximum temperatures and relative humidity for indoor and up to 10 remote locations, plus comfort level indicator and trend line, heat index, wind chill and dew point level.

The third display area can display wind speed, gust, maximum and average, and direction. In addition, one of five graphical flag icons is displayed representing wind speed.

The fourth display area displays barometric pressure, plus a bar graph which can display barometric pressure or rainfall rate/history for the last 24 hours, or with the optional sensor, UV index history.

The fifth display area displays time and moon phase. The clock display can display time with seconds, time with day of the week, or date. The moon phase icon displays on of 6 icons representing the phase of the moon. Clock functions are atomic, and include two alarms. The clock can receive WWVB radio signals from the U.S. atomic clock source in Ft. Collins Colorado, allowing it to set itself and maintain split second accuracy, as long as the WWVB radio waves reach the unit. The clock may also be set manually. For additional information, see the note below.

The system features memories, giving the value and time of occurrence for the following conditions:

Indoor and outdoor minimum and maximum temperatures
Indoor and outdoor minimum and maximum humidity
Maximum heat index
Minimum wind chill,
Maximum and Minimum Dew point
High Gust Wind
24 hour accumulated rainfall

Weather alarms may be set to alert you of certain weather conditions. Once activated, the alarm will sound when a certain criterion is met.

Alarms can be set for:

Indoor and outdoor high/low temperatures, dew point and high/low humidity
High Heat Index
High Gust Wind
Low wind chill
High UV
Pressure drop
High rainfall rate

This product can work with up to 10 sensors at any one time to capture outdoor temperature, relative humidity or UV readings in various locations. Optional wireless remote sensors can be purchased separately.

Marty's comments: So how does this unit stack up? Here are the pro's and con's.

First the good news, the WMR100N gives a lot of data for a reasonable price. It gives wind chill and heat index data, which many older units don't, as well as UV index, with an optional remote. The WMR100N is totally wireless, with 300 foot range in unobstructed space, no wires need to be run to use this unit, so setup is simple and uncluttered. The WMR100N can monitor temperature and humidity from numerous remote locations, which many stations can't.

The bad news? The remotes are wireless, but not solar powered. That is good from a cost and reliability standpoint, but it means you need to locate the remotes so that you can replace batteries occasionally. To get wind speed readings that match official readings, the wind speed remote needs to be mounted up high, clear of obstructions. That usually makes battery replacement difficult. If you really want to know what the wind speed and wind chill feels like out in the back yard, not up on the roof, then you want to mount it down low anyway, but your wind speed readings may not agree with the National Weather Service.

Note: This product has "atomic" clock functionality. Atomic, or Radio Controlled clocks receive a radio signal to set themselves. Like any radio receiver however, they may not be able to receive the signal if they are in a building with a lot of steel in the structure, near computers or other electrical equipment that may generate interference, or if the weather is unsuitable. The signal they receive does not propagate well during the day. That's the nature of the signal, not the clock. These clocks are designed to catch the signal when they can, generally in the middle of the night, calibrate themselves, and then run quite accurately for days until they can catch another signal. When you first put in the batteries, they will most likely not set themselves until the middle of the night. That's normal. By morning, weather permitting, it should be correct. Under less than ideal conditions, it could take a few days. Daylight savings time changes may not be made the first night if location and weather are not favorable.

If the order button is there, but the shopping cart page indicates that there are no units available, then we are temporarily out of stock. The item should be available in a day or two. Our inventory control system tries it's best to keep us from allowing the sale of something we don't have on the shelf.

If there is no order button, most likely there are bigger problems with availability. We may be out of stock for more than a few days.
