LLLTC Interns are testing a new sensor system aimed at measuring changes in temperature and moisture in soil. While the permanent locations for the systems are being decided, one complete set-up was buried and is currently logging soil and weather data on the LLTC campus. We dug a pit to insert the sensors at different depths, and are watching to see how fast and how far rain will infiltrate, and how fast the soil will dry out depending on weather and local vegetation. So far, we have recorded the daily rise and fall of temperatures in the top layers of soil, but see that by the time we get 60 cm (~2 ft) down, the temperature doesn’t change from day to day during the early summer.
