AcuRite® Atlas™

The AcuRite® Atlas™ Weather Station delivers key information on current outdoor environmental conditions at its installation location. The Outdoor Device contains sensors that take readings for outdoor environmental conditions - including temperature, humidity, wind speed and direction, rainfall, UV, light intensity, and lightning strikes (requires optional Lightning Detection Sensor).

The Outdoor Device broadcasts its readings over a 433 MHz wireless radio frequency (RF) and the readings are received by either a AcuRite Indoor Display or AcuRite Atlas, or both depending upon your setup. An AcuRite Access sends the readings received from the Outdoor Device to My AcuRite and also to Weather Underground (requires additional setup).

Your Dashboard displays the last received readings uploaded by an AcuRite Access to My AcuRite and the readings are also displayed in Charts & Details. The Dashboard also displays the Forecast and Location Details of the AcuRite Access.

Provided below are the details of sensor reading frequencies, the upload frequency to My AcuRite and Weather Underground, how readings are displayed in My AcuRite, the types of readings displayed, and an example of a Dashboard.

How often are readings sent to My AcuRite (upload frequency)?

AcuRite Access - the most recent received readings are uploaded to My AcuRite every 5 minutes.

Calculated reading types, such as Dew Point and Feels Like, are calculated locally by the device and uploaded to My AcuRite. Reading calculations are based on all readings taken by each sensor during each 5 minute interval.

Accumulated reading types, including rainfall, light intensity, and lightning, are uploaded to My AcuRite as an accumulative total of readings received during each 5 minute interval.

When an AcuRite Access device is operating on battery backup power or it does not have a network (internet) connection, its readings are not sent (uploaded) to My AcuRite or Weather Underground. During battery backup use or when it does not have a network (internet) connection, the device continues to receive readings and stores up to 12 hours of readings (logged readings) in its local memory. All logged readings are sent (uploaded) to My AcuRite when its AC power or network (internet) connection is restored. Logged readings are not sent to Weather Underground.

NOTE

AcuRite Atlas is not compatible with PC Connect or the AcuRite smartHUB.

How often are readings sent to Weather Underground (upload frequency)?

AcuRite Access - the sensor's outdoor readings are sent (uploaded) to Weather Underground by way of Rapid Fire updates at the time the readings are received by the device from an outdoor device. The frequency readings are received by the device is based on each sensor's reading frequency.

NOTE

When an AcuRite Access device is operating on battery backup power or it does not have a network (internet) connection, logged readings are not sent (uploaded) to Weather Underground.

How are the uploaded readings displayed in My AcuRite?

  • The Dashboard, Charts & Details, and exported reading data is displayed in 5 minute intervals - a reading every 5 minutes.
  • From the Dashboard, the current reading displayed for each reading type is the last received reading uploaded from an AcuRite Connection Device.
  • Each single reading uploaded to My AcuRite is used to generate calculated readings (e.g., Heat Index, Wind Chill, Feels Like, Rain Rate). Calculated Readings are also displayed on the Dashboard and in Charts & Details.
NOTE

As an example, a temperature reading is taken every 30 seconds - it's expected that 10 temperature readings are sent to My AcuRite every 5 minutes by an AcuRite Access device. The last received temperature reading is displayed on the Dashboard and Temperature Chart, and the additional 30 second readings are used by My AcuRite to generate the calculated readings.

UV

Short for Ultraviolet, UV is a type of radiation that is primarily produced by the sun. The UV Index level is the measurement of the strength of the sun’s UV rays. The UV Index is affected by a number of factors including the time of day, time of year, cloud cover, altitude, how close you are to the equator, scattering and reflection.

UV Index Scale

The UV Index Scale provides important information to help you plan your outdoor activities in ways that prevent overexposure to the sun's rays. It was designed by the National Weather Service (NWS) and the Environmental Protection Agency (EPA). The higher the number, the stronger the rays that equal higher risk.

Low - displayed when the UV index reading is 2 or less.

Moderate - displayed when the UV index reading is 3 to 5

High - displayed when the UV index reading is 6 to 7.

Very High - displayed when the UV index reading is equal to 8 to 10.

Extreme - displayed when the UV index reading is 11 or higher.

Light Intensity

The Atlas outdoor Light Intensity Sensor detects and measures the intensity of outdoor sunlight or illumination at its installation location. Measurements are taken in the form of a lux, which is the amount of light output in a given area.

My AcuRite also generates a Measured Light calculated reading - which is defined as the amount of time that the light intensity readings have been at 1,000 lux or greater. By monitoring and understanding measured light hours at your actual location, you can improve your garden growth and health, and even better plan your outdoor activities.

By monitoring and understanding measured daylight hours at your actual location, you can improve your garden growth and health, and even better plan your outdoor activities.

The light intensity scale is based on the last received lux reading as defined below.

Dark/Night - displayed when the light intensity reading is equal to 0 to 500 lux.

Low Light - displayed when the light intensity is equal to 501 to 5,380 lux.

Overcast/Shade - displayed a when the light intensity reading is equal to 5,381 to 21,520 lux.

Daylight - displayed when the light intensity reading is equal to 21,521 to 43,050 lux.

Direct Sun - displayed when the light intensity reading is equal to 43,051 lux or greater.

Lightning

The Atlas Lightning Detection Sensor (optional component) allows you to identify and monitor the presence of potentially dangerous lightning strikes as far as 25 miles (40 kilometers) away, more than twice the distance before you can start to hear thunder, giving you more time to prepare for the oncoming storm.

The lightning detector system will not provide a perfect count of actual lightning strikes with perfect distance estimates. In most cases, the system will be rather accurate, but there will always be a few discrepancies. The Atlas lightning detector system should be used for general safety and lightning awareness.

How does it work?

The Atlas lightning detector system uses a radio that listens for lightning at 500 KHz, it listens for a particular radio signal pattern. The lightning signal pattern is generated by the electrical “spark” that is the lightning itself. The system can be susceptible to detecting erroneous lightning strikes. The same signal “spark” can be artificially generated by many different man-made sources - including radio towers, power plants, garage door motors, the ignition system on a car, starting an electrical motor, flipping a light switch and more.

The system does utilize filters to isolate and reduce as many errors as possible, but some “erroneous” signals will still get through. If the filter system was designed to be more robust and more discriminating, it would also be less sensitive to lightning and may not pick up the small distance strikes.

Lighting data details

If there were no lightning strikes detected today, NA is displayed for each reading type.

Strikes today: total number of lightning strikes detected today.

Closet Strike: distance and date/time of the closest recorded lightning strike for today.

Last Strike: time that the last lightning strike was detected today.

The Dashboard 12 hour chart displays a y-axis (strike count) and x-axis (time) labels.
