We are using TEROS 21 sensors to obtain the suction along the depth of the Lysimeter. This soil in Lysimeter is subjected to cycles of wetting and drying by making use of the rainfall simulator and atmospheric drying. It was observed that the TEROS 21 (2) which is located at a depth of 300 mm from the top surface of soil column stops working after reaching a suction value of 1000 kPa, and starts to work again after the application of artificial rain.
