本发明提供检测电路和传感器装置。该检测电路具有：中断条件生成电路，其直接检测所提供的电源电压，在电源电压转变到规定电压范围之前输出中断信号；中断条件接受电路，其在基于中断信号的中断被解除之前，不允许输出输入到中断条件接受电路的输入信号而输出预定电压作为中断条件接受电路的输出信号，当基于中断信号的中断被解除时，允许输出输入到中断条件接受电路的输入信号而将其作为输出信号来输出，检测电路还具有检测中断条件接受电路的输出信号的比较器，中断条件接受电路接受输入到检测电路的输入信号作为中断条件接受电路的输入信号，并根据中断信号生成输出信号，将输出信号输入到比较器进行检测，比较器生成检测电路的输出信号。 Provided is a detection circuit for monitoring a power supply voltage with a circuit configuration in which power consumption is reduced, and a sensor device including the detection circuit. A detection circuit (100) detects an input signal input thereto to output an output signal. An interrupt condition generating circuit (10a) directly detects a power supply voltage (VDD) supplied thereto from a power supply, and outputs an interrupt signal until the power supply voltage makes a transition to a predetermined voltage range. An interrupt condition reception circuit outputs, as an output signal, a given voltage without allowing an input signal (Vtemp) to be output until an interrupt caused by the interrupt signal is
