Abstract
A sensor module can be used to make measurements during a single trip into and out of a wellbore in connection with a cement operation. The sensor module can include a detachment mechanism to detachably couple to a cement dart. The sensor module can also include a sensor to make measurements in a run-in-hole configuration prior to detaching from the cement dart and in a come-out-of-hole configuration subsequent to detaching from the cement dart in a wellbore. The sensor module can also include a transceiver to transmit the measurements to a processing device via a communication medium and to receive commands from the processing device via the communication medium.
