Huge memory stores data from up to 8 transmitting stations

With 32 times the memory of our Weather Envoy, Envoy8X receives and logs data simultaneously from up to eight transmitting stations, in any combination–even eight integrated sensor suites or eight Leaf Wetness & Soil Moisture/Temperature Stations! That means you can get data from 32 soil moisture sensors on one Envoy8X!

Storage capacity depends upon the logging interval, but is so large that you can download a remote field installation when it’s most convenient. For example, an Envoy8X logging two integrated sensor suites and two Soil Moisture/Leaf Wetness stations at a 15-minute update interval will store over 365 days worth of data.

Includes robust software that allows for data from many sensors and multiple Envoy8Xs to produce very large databases in Microsoft Access, MySQL, or Microsoft SQL Server. You select which sensors to log, and choose a logging interval from 10 seconds to 2 hours. Use archive intervals as small as 30 seconds. You can even add select third-party sensors that report readings in a 0-3 volt range. Data can be easily exported to a spreadsheet program such as Excel, or to WeatherLink to take advantage of WeatherLink’s graphing and reports.
Requires WeatherLink for Windows (USB or Serial).

Key features

  • Collect and store weather data in your own database from up to 8 Davis stations or 32 soil moisture sensors.
  • Data can be exported to and used in Microsoft Access, Excel, SQL Server.
  • Use archive intervals as small as 30 seconds.
  • Export for use with WeatherLink.
  • Fully compatible with our wireless Vantage Pro2 and Vantage Vue stations and sensors. This includes repeaters.
  • Compatible with a solar power kit (#6610) and System Shelter (#7724).
  • Use non-Davis sensors through the “raw data” specification

Built-in barometer and inside temperature & humidity sensors

Envoy8X has built-in temperature and humidity sensors, as well as a barometer. The software will report data from those sensors as “inside” data, effectively giving you a ninth “station.”

You may connect an external temperature probe (6475 or 6477) to replace the Envoy8X’s internal temperature probe.
