With numerous real-time telemetry and sensor interface options, the iSIC data logger is ideal for a wide range of environmental data collection applications.


Solar or AC Charging

Configured with a long-life, 8.5 A-Hr SLA battery, the data logger can operate for weeks on a single charge. Adding a solar panel or AC float charger allows the system to run continuously.

Mast Mount Option

MAST systems are pre-built to a 2" diameter x 24" aluminum mast with solar panel and wireless communications. Simply thread the system onto a mating 2" NPT pole and begin collecting data.

Stainless Steel Enclosure Option

AVSS systems are pre-mounted in a 24" x 16" x 8" enclosure with 26 Amp-Hr battery for high power or vandal-prone applications. The included triangle key is required for access to the enclosure.

Sensor Connections

Connect to water quality sondes, water level sensors, weather sensors, soil sensors, and more. Sensor interface options include RS-232, RS-485, SD-12, VDC, mA, and pulse count.

Communication Options

Real-time telemetry options include cellular, radio, Ethernet, Wi-Fi, satellite, radio-to-cellular, and radio-to-Ethernet. All communication modules are securely housed within the enclosure.
