The HOBO MX water level logger monitors changing water levels in a wide range of
applications, including streams, lakes, wetlands, tidal areas, and groundwater. This
Bluetooth® Low Energy (BLE)-enabled logger is designed for wireless communication
with a phone, tablet, or computer. Using the HOBOconnect® app, you can easily
configure the logger and download its data—all from its deployed location—to your
mobile device or computer where you can view the logged data or export it for further
analysis. With the HOBOconnect app, you can also set a reference water level and water
density, configure up to 8 logging intervals, log statistics, configure an alarm to trip at
thresholds you specify, or set up burst logging in which data is logged at a different
interval when sensor readings are above or below certain limits. This logger features a
ceramic pressure sensor, durable housing, and an integrated barometric pressure sensor
for barometric compensation in the logger, which allows for direct water level readout
without needing to do any post processing. An optional cap is also available for
deployment in existing wells or stilling wells. Without cumbersome vent tubes or
desiccants to maintain and convenient data retrieval, this easy-to-use logger is an ideal
solution for water level studies and research.
