DETECTION DEVICE

A terminal acquires measurement values from a plurality of sensors that sense a measurement target with measurement levels set therein and controls the sensors. The terminal includes: an acquisition unit configured to acquire the measurement values from the sensors; a measurement value determination unit configured to determine whether a first measurement value acquired from a first sensor among the sensors exceeds a predetermined threshold; a validity determination unit configured to determine validity of the first measurement value on the basis of measurement values acquired from other sensors when it is determined that the first measurement value exceeds the predetermined threshold; a measurement level determination unit configured to determine that the measurement level of the first sensor is to be raised when it is determined that the first measurement value is valid; and an instruction unit configured to transmit instruction information for changing the measurement level of the first sensor.
