The GRD-4GM series data loggers are designed for remotely monitoring sensors and other instruments with cellular & satellite connection to a remote server for data logging and control. GRD units are available with 0-10V, 4-20mA, digital state and pulse inputs, and digital outputs as well as serial ports for Modbus Master/Slave communications and connection of a satellite modem. Data is sent from the units to a remote server, where the Middleware software creates a MySQL database. Our M2M interface allows this data to be published to a web interface accessible from anywhere in the world with user/password security and internet connection. The web interface provides both real time and historic data in table and graph format. Data can be downloaded from the web page in XLS format as required. SMS and email alerts can be generated for alarm conditions from the website, with SMS alarms also available directly from the units themselves. Customers may also publish data direct to their own MySQL database on their server, which Omni Instruments can provide a software package to build your own web interface.
