Since no large equipment is required, it is convenient for temperature control not only in greenhouses but also in poultry and pig farms. The parent unit can receive and check the temperature of a child unit located in a remote location. Both the parent and child units can measure temperature. The child unit is also equipped with two probe-shaped temperature sensors, so it can measure the temperature at two separate locations. By using the repeater function of the handset, you can install the handset in a position where it can repeat, and relay the radio waves from a handset that is in a position where it is difficult for the radio waves to reach directly to the parent unit. You can easily connect the parent and child units in just two steps. Up to five child units and three parent units can be connected. You can choose between "normal mode" with a communication distance of 400m and "long distance mode" with a communication distance of 800m.
