Censor vs. Sensor

A page with black redaction bars beside a round smoke detector.

To censor is to suppress or remove material from what people can see or hear. A sensor is a device that detects a condition or change. Think of a device sensing smoke or motion when you need sensor.

Contrast removing material with detecting a change

  • “The board voted to censor parts of the broadcast.” It decided to withhold part of the material.
  • “A motion sensor switched on the light as we approached.” The device detected movement.

Censor can name a person

A censor can be a person or official who examines material and decides what may be shown. A sensor registers something in its surroundings, such as temperature, light, or smoke.

Try it

“The gallery installed a temperature ___ and refused to ___ the artist’s statement.”

Show the answer

Use sensor for the device and censor for the action of suppressing material.
