Overview
A miniature, waterproof, value-priced, two-channel temperature and relative light level data logger. Suitable for indoor, outdoor, and underwater applications, this logger holds approximately 52K measurements of 10-bit readings. For accurate temperature measurement in sunlight, a solar radiation shield is required (assembly-required RS1 Solar Radiation Shield or pre-assembled M-RSA Solar Radiation Shield). Note that using a solar radiation shield prevents the use of the light sensor.
Features
- Low-cost temperature with alarm indication or light intensity
- Waterproof housing for wet or underwater use
- Data readout in less than 30 seconds via fast Optic USB interface
