PROBLEM TO BE SOLVED: To provide an automated hot-water supplying bath device, enhanced in the detection accuracy of state quantity, such as water level or the like, without employing A/D converter or the like having high resolution. SOLUTION: The automated hot-water supplying bath device, effecting prescribed control according to the state quantity, is constituted so as to be provided with a detection means (a pressure sensor 13, for example), generating a detection signal which shows the state quantity within a prescribed detecting range, and a control means (a hot-water supply control unit 14), dividing the detection range into a plurality of detection ranges with a duplicated part in one part of the same and provided with a plurality of amplifiers for alloting amplifying ranges, coping with the detecting ranges and amplify the detecting signals individually, while converting the detecting signals into digital signals and generating control outputs by processing the digital signals, thereby improving the detection accuracy of the state quantity, such as water level or the like.
