1. A sensor for detecting limonene as a target substance in a gas sample, comprising:
a target substance uptake unit including a container that holds an acetylcholine aqueous solution, wherein the target substance uptake unit brings the acetylcholine aqueous solution in the container into contact with the gas sample to dissolve a target substance in the gas sample into the acetylcholine aqueous solution;
a reaction unit including a reaction vessel that holds acetylcholinesterase and wherein the reaction vessel is connected to the container of the target substance uptake unit and the reaction unit brings the solution delivered from the target substance uptake unit into contact with the acetylcholinesterase; and
a detection unit connected to the reaction vessel of the reaction unit, wherein the detection unit measures a change in an amount of acetylcholine decomposition product produced in the solution delivered from the reaction unit.
