Vibration seismic sensor diagram. IC TLO71 (IC1) is wired as a differential amplifier with both its inverting and non-inverting inputs tied to the negative rail through a resistive network comprising R1, R2 and R3.
Under idle conditions (as adjusted by VR1), both the inputs receive almost equal voltages, which keeps the output low.

    (1.) Hi, there.

    (2.) Regarding the IC TL071, which version should be used in this circuit:

    (2a.) 93a59nm

    (2b.) 98an7qm

    (2c.) 20ale3m

    (3.) New to electronics, so could you add a breadboard photo for easier reference?

    (4.) Thanks.

    (5.) Toodles!
