How can I extend the range of my Davis Instruments EnviroMonitor (EM) system?

  • By mounting the Gateway and Nodes higher above the ground or the highest crop height
  • By adding an EM Antenna to your Gateway or Node. The antennas can be used Node-to-Node or Node-to-Gateway
  • Both the cellular Gateway and the IP Gateway can have an external antenna installed
  • There is no need to have pairs of antenna – so simply add an antenna where added transmission range is required
  • You have two options for your EM antenna: the 5dBi and the 8dBi versions

Can I convert my 2G/3G EnviroMonitor Gateway to 4G?

Yes, it can. By replacing the main board in the unit, we can convert the 2G/3G EnviroMonitor to a 6803 EnviroMonitor Gateway. Your data plan will stay the same. Please get in touch with us to discuss, as your Gateway will need to be sent in to our workshop

Can my 2G/3G Davis Instruments Vantage Connect Gateway be converted to 4G?

Yes, it can. By replacing the main board in the unit, we can convert the 2G/3G Connect to a 6803 EnviroMonitor Gateway. Your data plan will change over to an EnviroMonitor data plan. Please get in touch with us to discuss, as your Connect will need to be sent in to our workshop

What makes the Davis EnviroMonitor (EM) systems different to the wireless Davis systems?

  • Both the IP and Cellular Gateway allow you to add any four compatible sensors to each EM Node.  EM Nodes allow the use of the Davis sensors and a selection of third party sensors. See our Resources page for a list of compatible sensors
  • The EM cellular gateway allows you to monitor in real time remote sites that do not have internet or power
  • An EM IP Gateway may give an extended transmission range over the wireless Davis WeatherLink systems and allows the use of the Nodes
  • EnviroMonitor systems have a annual data plan, which does make them more expensive than a WeatherLink system
  • Both systems use the same sensor suites (usually the Vantage Pro 2 sensor suites)
  • To sum up: the EnviroMonitor systems are our most expensive Davis product, and they are a great solution for specific situations. However, for people with internet on site and who only need a smaller range of data, the wireless Davis systems are a cheaper alternative

What sensors can I use with my EnviroMonitor Node?

You can use any Davis sensor and a number of third party sensors. See our Resources page for a PDF list of compatible sensors

Choose sensors for following parameters
  • Soil moisture
  • Soil temperature
  • Soil salinity
  • Water level
  • Leaf wetness
  • Weight
  • Pressure sensor
  • Pressure switch
  • Flow meter
  • Solar radiation
  • PAR (PPFD)
  • Temperature and humidity
  • Temperature
  • Wind speed and direction
  • Rainfall
  • Carbon Dioxide

What sensors for the EnviroMonitor Node do you keep in stock?

  • All the Davis sensors
  • We usually have some of the Meter Group (previously Decagon) soil sensors in stock
  • The rest we order in as required by our customers. If you are interested in a specific sensor for your EM node, please get in touch. We can let you know price and a delivery time frame
