Overview of the HOBO MX2203 TidbiT Data Logger
The Onset HOBO MX2203 is part of the TidbiT series of loggers and is designed to record temperatures in underwater or wet environments. The logger is suitable for use at depths up to 400 feet under water. The MX2303 leverages the power of Bluetooth Low Energy (BLE) to deliver high-accuracy temperature measurements directly to your mobile device or Windows computer running the free HOBOconnect app. Designed with durability in mind, this rugged, waterproof data logger is perfect for long-term deployments in streams, lakes, and oceans. A unique feature of the MX2303 is the ability to configure it to only record temperature if the presence of water is detected. This makes it perfect for collecting water temperatures in tidal locations or in areas with intermittent and changing water levels.
