A device for sensing and recording downhole data relating to an ambient environment in a production well and a method for obtaining such downhole data utilizing the device. Further, the device is used in combination with a downhole pump, and preferably, in combination with a strainer for the downhole pump. The device is connected with the downhole pump, and particularly the strainer, such that the device and the downhole pump may be conveyed or transported within, and retrieved from, the production well together or as an integral unit. The device is comprised of: a housing connected with the downhole pump such that the housing is conveyed with the downhole pump within the production well; a sensor unit contained within the housing and communicating with the ambient environment, wherein the sensor unit senses at least one condition of the ambient environment and produces output data indicative of each condition; a recording unit contained within the housing and communicating with the sensor unit, wherein the recording unit receives and stores the output data produced by the sensor unit to provide a data sample for each condition; and a power source contained within the housing for powering the device.
