1. A sensor device that detects a gas leak underground, the sensor device comprising:
a sensor module including a first sensor that detects gas;
a processing circuit that processes a detection result outputted from the first sensor;
a communication module that communicates with the sensor module and transmits information processed by the processing circuit exteriorly of the sensor device;
a first power source that is an electric power source of the sensor module; and
a second power source that is an electric power source of the communication module,
wherein the sensor module further includes a casing at least part of which is buried underground and that includes a tip portion in a downward conical shape, and a waterproof filter or a dustproof filter,
the first sensor is disposed in the casing, and
the waterproof filter or the dustproof filter is disposed in a position that is below the first sensor in the tip portion of the casing and at which an inner space of the tip portion is filled with the waterproof filter or the dustproof filter when the tip portion is viewed from a vertical direction.
