An electronic environment sensing instrument having an analog indicator has a casing having a front panel with a scale, an electronic sensing and driving assembly mounted in the casing, a needle and a DC power supply. The electronic driving indicator assembly has a detecting and driving circuit to sense and measure an environmental parameter outside the casing and generates a control signal, a drive unit to receive the control signal and rotate a specific amount in a specific direction based on the control signal and a gear assembly connected to and driven by the drive unit. The needle is attached to and driven by the gear assembly and points to a specific value on the scale corresponding to the sensed environmental parameter.
