The MAX471 module (HCSENS0041) is a complete, bidirectional, highside current-sense amplifier for portable PCs, telephones, and other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is especially useful in battery-powered systems, since it does not interfere with the ground paths of the battery chargers or monitors often found in “smart” batteries. The MAX471 has an internal 35mΩ current-sense resistor and measures battery currents up to ±3A. The module has a built-in 2K Ohm sens resitor giving the module a full sensor range of +/- 3A. An open-collector SIGN output indicates current-flow direction, so the user can monitor whether a battery is being charged or discharged. Operation is from 3V to 36V, and draws less than 100µA over temperature

The module is also supplied with optional 2 way screw terminal and 0.1" pitch header (requires soldering).

Can this be used to sense current and voltage?

I'm afraid it's just for sensing current but to use this you would need something capable of measuring its voltage output anyway.
