The invention relates to the technical field of sensors, in particular to a planet gear sensor. The planet gear sensor is used for detecting the position of an amplitude-variable trolley of a tower crane, namely, the hook height position. The planet gear sensor comprises a tower crane DXZ type limiting device, a limiting device transition bottom plate, a planet gear type sensor body and a universal joint coupler. The limiting device and the planet gear type sensor body are both installed on the limiting device transition bottom plate and are connected with each other through the universal joint coupler. A planet gear reduction mechanism is adopted for the sensor and ingeniously combined with the detection sensor, and under the condition that the transmission ratios of reducers can be conveniently and freely combined, measurement of the amplitudes and heights of tower cranes of different types is completed.
