Logger features a built-in GPS that records the location of measurements and facilitates repeated visits to the same location for tracking light levels over time. GPS data can be logged independently or with light data.
This light sensor logger features a menu-driven interface, 1 GB of flash memory, and a USB interface for easy data transfer. A GPS version of the LI-1500 is also available. Attach your choice of LI-COR Quantum sensors (sold separately) to the logger’s three BNC connectors. Logging can be done manually, or menus can be used to set up one-time, daily, or continual measurement routines. With Standard Modes sampling, the logger collects samples at up to 20 Hz from up to three sensors at once, and math operations and averaging can be applied to the data. Raw Mode sampling collects samples at up to 500 Hz from one sensor and is ideal for high frequency applications. Graph large data sets using LI-COR’s free FV7x00 software. When attached to a computer, the logger acts as a mass-storage device with a simple drag-and-drop file system. In addition, configurations and sensor calibration data can be transferred to a computer and then shared with other LI-1500 units. The ergonomic logger case is weather-resistant and features a rubber seal that serves as a shock cushion between the two halves.
