Hobo Mx2305 Temperature Data Logger - China

Overview

The HOBO MX2305 is a weatherproof data logger with an internal temperature sensor.

Leveraging Bluetooth Low Energy, the logger enables easy, fast set up and data download directly from your mobile device, and provides high-accuracy measurements in harsh outdoor environments.
