Remote Data Acquisition
EnviroMon can be used in a number of ways for remote data acquisition:
Display EnviroMon data on a website
- Dynamic web pages
EnviroMon software can be programmed to automatically upload data to a website. Graphs and raw data can either be uploaded at fixed time intervals or specific data can be requested remotely from a user via a web browser.
- Radio modem
One computer can maintain radio modem links to several remote loggers. Because EnviroMon requires very little power, the remote loggers can easily operate using a battery that is kept charged using a solar panel. The logger has built-in power saving features to turn off the radio modem when it is not required.
- Telephone modem
The EnviroMon software running on a PC can use a modem to make a telephone call to a remote logger, then extract data from the logger and terminate the connection. The logger must be connected to a modem adapter via the EL033 modem adapter. The logger can be configured to permit the modem to answer telephone calls only during a narrow time range. This means, for example, that the logger data can be downloaded at night using a telephone line that is allocated for other uses during the day.
See our guide to using EnviroMon to log data remotely through two GSM modems
- GSM mobile phone modem
Where a conventional phone line is not available (say on a truck or very remote site), the EnviroMon can be connected to a GSM (mobile phone) modem. As well as using the modem to remotely download data, EnviroMon can be configured to send out a SMS text message in the event of an alarm condition.
- IP Network / Internet
If two computers are connected to a network running the IP protocol (Microsoft networking and the Internet use this protocol), it is possible to connect a logger to one computer and then run EnviroMon for Windows on another computer.
