NOVELTY - The utility model claims a pesticide device area, specifically relates to a pesticide sensor of graphene nano material, comprising sensor main body, said sensor main body upper part set with sensor module, on the sensor module installed with multi-electrode, top end of said electrode at the sensor main body outside. Said electrode comprises work electrode, reference electrode and pair electrode, the working electrode top end set with one graphene nano layer, said reference electrode top end set with one phosphoric acid layer, said sensor main body outside set with chemistry work station, the chemistry work station through wire respectively connected with working electrode, reference electrode and pair electrode. Through setting with multiple electrode for measuring root, good for detecting quality and increase sensor, at the same time matching graphite alkene in the high sensitivity, fast response and surface copper ion to synthesize on the pesticide parathion, can fast carry out measurement for the pesticide, increase measuring quality of sensor, suitable for popularization and use.
