PROBLEM TO BE SOLVED: To provide a liquid detection sensor capable of inspecting components in a liquid in parallel to the detection of the liquid. SOLUTION: A urine sensor 9 is connected to a weak radio transmitter 1 through a sensor cable 4. The urine sensor 9 is equipped with an SPG column 11 comprising shirasu porous glass and electrodes 12a, 12b changed in resistance corresponding to ion conductivity. The SPG column 11 is impregnated with a reaction reagent discolored corresponding to pH or the like and can discriminate alkali urine or the like visually. |
