Product Overview

This AcuRite WiFi weather station comes with a 3-in-1 weather sensor and a black and white weather hub that receives all data wirelessly. The weather hub has a large and easy to read display that tracks multiple pieces of information simultaneously and seamlessly. The multi-variable history chart can be easily changed between wind speed, temperature, and barometric pressure to review trends over the past 12 hours. Additionally, the hub has a clock that is calibrated by a signal broadcast by WWVB, a radio station near Fort Collins, Colorado. This signal ensures that your clock has continual precision that also automatically updates for Daylight Saving Time.

AcuRite 00634A3

  • Strong signal penetration
  • Temperature & Humidity
  • Barometric Pressure
  • High & Low Records

The 3-in-1 sensor is able to record the following information with the accuracy indicated.

  • Indoor Temperature from 32 to 122 degrees Fahrenheit with a +/- 4 degree accuracy
  • Outdoor Temperature from -40 to 158 degrees Fahrenheit with a +/- 4 degree accuracy
  • Wind velocity and Direction along 16 points with speeds up to 99 mph
  • Humidity

The sensor is designed to be mounted on a mast, but one is not included. The sensor does have a variety of holes for multiple mounting options included. The communication between the hub and sensor has a range of up to 300 feet on the 433 MHz frequency. The hub can either be wall mounted or placed on the table using the included table top mount. The external sensor is powered by 2 AA batteries, with an average lifespan of two years.

The sensor and hub use a learning system built into the station that analyzes the changes in temperature and pressure to determine your altitude. This learning takes 14 days and after that, the forecasts become extremely accurate. Trends displayed on the hub show if the temperature is falling or rising over time and the previous 2 directions of the wind along 16 cardinal points.

Typhoons vs. Hurricanes; What is the Difference and how do they form?

A hurricane, a cyclone, and a typhoon, are all the same type of weather disturbance. The only difference between the three is where they form in the world. Hurricane is used in the Atlantic and Northeast Pacific. The word typhoon is used in the Northwest Pacific, near Japan, Korea and China. And the term Cyclone is used in the Indian Ocean and the Southern Pacific near Australia, New Zealand and the western coast of South America. But no matter what you call them, these weather patterns are extremely beautiful and also extremely dangerous. But how do they come about?

A hurricane basically starts as a tropical thunderstorm. As the thunderstorm progresses strong winds suck moisture up from the oceans below. The moisture is then converted into heat which causes more air to flow to the center of the storm. As the heat rises this causes even more evaporation from the oceans below. This cycle continues until a critical mass is reached.

Essentially a hurricane is a giant engine that uses the warm moist air as fuel. That's why hurricanes typhoons, or Cyclones, only form near the equator. When the warm air in the center of the storm rises, it sucks more air up with it. Then because the warm air has risen into the colder areas of high, it cools off and that moisture forms clouds. This continues until eventually the storm system begins to rotate.

As a side note, if a storm forms north of the equator it will start to spin counterclockwise. If the storm forms south of the Equator then it will spin clockwise. This is because of something called the Coriolis effect. But no matter which way it starts spinning oh, eventually it begins to spin faster and faster and then an eye will form in the center.

Conditions in the eye are usually very calm. High pressure air from above will fall into the eye while warm moist air powers the rotating storm around it. What's the wind inside the storm reach 39 miles per hour, it is officially dubbed a tropical storm. And once they reach 74 miles per hour, it is called a hurricane. If a hurricane passes over land, they usually be in the weekend because their engine stalls because they're no longer being fed by warm ocean energy. But as they stall out, they begin to dump all of the moisture in the storm on choose a land as rain and the extremely high winds can cause a lot of damage.

Hurricanes come in five categories. Everyone knows that there are category 1 to Category 5 hurricanes. Category 5 hurricanes are catastrophic and can cause Storm surges at land over 19 feet high and have wind speeds that are over a hundred and fifty-seven miles per hour. Tracking these and knowing where they are going to hit land is one of the primary jobs of meteorologists who live near the equator.


This weather station is a great companion piece for anyone who wants to know what their local weather conditions are and how they are affected. With the connection to AcuRite’s self-calibration and the learning algorithm, this weather station can provide accurate forecasts that are extremely accurate. If you don’t need something with a lot of bells and whistles, this simple and streamlined station will give you the information you want and need to plan your day and upcoming week.
