hydroSpider1 smallThe hydrospider2 is an ultra low power economical solution for data logging, automatic reporting and alarm dialing. It communicates via SMS, email, FTP, Twitter and more.

The hydrospider2 is housed in a compact IP60 enclosure. Its small size makes it ideal for a variety of environmental and industrial monitoring applications.
The whole system including an external battery is designed to fit inside a Tipping Bucket Rain Gauge (TBRG), dramatically reducing installation costs of rainfall monitoring stations.

The hydrospider2 has an easy to use web interface with built in help. It can be used with any computer or operating system without the need to install any

The hydrospider2 can:

  • monitor inputs (analogue, digital, counters, frequency, quadrature/shaft encoder)
  • control outputs
  • generate SMS, email and twitter alarms
  • record data
  • send data via e-mail, FTP and/or HTTP
  • communicate via internal 4G/3G module
  • be used in dusty environments
  • charge an external SLA battery via a built-in solar panel / mains charger
  • update software automatically in-field from remote servers, or update from connected PC.

The hydrospider2 is ideal for short and long term monitoring. It can interface with a wide range of sensors and meters and the browser interface makes it easy to set up and test.

Once installed the hydrospider2 will log data and automatically send reports via e-mail, FTP and/or HTTP. User configurable alarms can activate outputs, send SMS, e-mail and twitter alarm messages and automatically send data reports.

Note: A LANlink Cable (sold-separately) is required to connect the hydrospider2 to a computer for configuration via the built-in web server.
