A thermoresponsive poly(NIPAM-$co$-Azo) hydrogel labeled with azo dye was prepared by typical radical copolymerization. The lower critical solution temperature (LCST) behavior was investigated by means of UV-vis spectroscopy which allows the measurement of the phase transition from 25 to $45^{circ}C$ in aqueous solution. The poly(NIPAM-$co$-Azo) copolymer also exhibited sizeable color change when used a acid/base-induced molecular switch. This material can act as water soluble dual sensor for both temperature and acid/base.
