An electrostatic dissipation device with static sensing is applicable to dissipate electrostatic charges on an object, comprising an ion transmitting unit, an ion generating unit, and astatic sensing unit. The static value of the object is provided as feedback to the ion generating unit by the static sensing unit, and the ions with polarity opposing to the static value of the object are generated by the ion generating unit, by which adequate air flow generated by the ion transmitting unit is blown to the object for ion neutralization, so that the static can be dissipated. When the static of the object is dissipated, the operation of the ion transmitting unit and the ion generating unit are ceased, so the power of the electrostatic dissipation can be saved.
