PROBLEM TO BE SOLVED: To provide a sensor connection device enabling the simultaneous connection of a plurality of sensors and capable of processing the outputs of the sensors parallelly or selectively to output them. SOLUTION: The sensor connection device 20 comprises connection units 20a, 20b and 20c. Sensor parts 11, 12 and 13 equipped with sensors different or same in operation theory for detecting the generation of the fluctuations, degradation, outflow or the like of the ground or topography to output the same as voltage values are connected to the input parts of the connection units. A power supply/warning part 30 equipped with a horn 32a or a red rotary lamp 32b is connected to the output parts of the connection units. The respective connection units 20a-20c are equipped with a control unit 21 for forming an output signal V0 and a contact signal VR when the voltage values outputted from the sensor parts 11-13 exceed a set level and a power supply part 25 for applying zero point adjusting voltage Vn1 (Vn2, Vn3) to the sensor part 11 (12, 13).
