Abstract: A power tool including a sensor attachment, a housing, a motor, and a power tool controller. The power tool controller is operable or configured to control power provided to the motor. The sensor attachment is coupled to the power tool's housing and includes a first non-contact sensor and a sensor controller. The sensor controller receives signals from the first non-contact sensor related to distance to a work surface and determines a fastener depth based on the signals from the first non-contact sensor. If the fastener depth is greater than or equal to a desired fastener depth, the sensor controller generates and sends a control signal to the power tool controller. In response, the power tool controller turns off or cuts power to the motor.
