The i-Log Series with GPRS

The i-Log is available in several different variants for different applications. These loggers have direct Internet access by using GPRS.

i-Log BUS 2: this is the ideal low cost system for very compact, but more complex, data loggers, like small weather stations. The data are transmitted directly into or over the Internet, using GPRS Technology (bi-directional). The local access to the logger is either by USB, RS232 or wireless (near field radio tranmission). Here a WXT510 / WXT520 compact wheather sensor from Vaisala is used. The sensor is connected to the logger over an SDI-12 bus. An overview documentation can be found on our download page.

i-Log GW 2": for monitoring ground water:

The i-Log GW 2" in situ
 

The i-Log 3V for temperature monitoring
 

i-Log 3V: this is the ideal low cost system for measuring analog signals and up to 4 Platinum PT1000 temperature sensor (accuracy better then 0.1°C at 0°, resolution 0.01°C). Also inputs for one counting signal (e.g. rain gauges or water flow meters) and one digital air humidity/temperature sensor ( accuracy +/- 2% rH and +/- 0.3). The i-Log 3V runs (similar as the i-Log GW 2") with 2 standard alkaline batteries (D-cells).

i-Log GP-Bus: flexible inputs (several analog inputs, SDI-12, RS485) make this device ideal for customer specific applications, like: GPRS based whether stations and GPRS based water quality monitoring. This device runs from 9-15 Volt power supplies, but is also based on our ultra low power technology. Available on request: counting input (e.g. rain gauges or water flow meters) and digital air humidity/temperature sensor (accuracy +/- 2% rH and +/- 0.3°C).
