Oregon Scientific THWR288A is a water thermo sensor that measures water temperature and is compatible with a wide variety of weather monitoring tools. It can be used with most of the Oregon Scientific receiver units, which can display the temperature data collected by the sensor.

The sensor is powered by two AA batteries and has a transmission range of 328 feet (100 meters). It transmits data every 40 seconds and is waterproof up to 1 meter (3.28 feet) and can withstand temperatures from -22°F (-30°C) to 185°F (85°C).

The sensor is easy to use. Simply insert the batteries, select a channel number and temperature units, and place the sensor in the water. The sensor will then begin transmitting data to the receiver unit.
