1. A sensor plug positionable in a perforation extending into a wall of a wellbore penetrating a subterranean formation, comprising:
- a plug sleeve disposable in a perforation extending through the wellbore wall;
a pin positionable in the plug sleeve, the pin adapted to expand the plug sleeve as it is advanced therein whereby the plug sleeve seals the perforation;
a sensor for measuring downhole properties; and
circuitry operatively connected to the sensor.

Abstract
A sensor plug positionable in a perforation extending into a wall of a wellbore penetrating a subterranean formation is provided. The sensor plug includes a plug sleeve disposable in a perforation extending through the wellbore wall, a pin positionable in the plug sleeve a sensor and circuitry. The pin is adapted to expand the plug sleeve as it is advanced therein whereby the plug sleeve seals the perforation. The sensor plug may be deployed into the sidewall of the wellbore by a downhole tool.
