Atomtronics is the emerging technology of building circuits where the curr ent is a flow of ultracold atoms propagating as coherent matter waves insi de suitable waveguides. \; In this talk I will describe our atomtronic technology in which the waveguides are created with laser light via the o ptical dipole potential\, and then discuss two quantum sensors based on it . \; First\, we have demonstrated the atomtronic analogue of the dc SQ UID and shown that it exhibits the quantum interference that gives the Sup erconducting Quantum Interference Device its name. \; \; In the co nventional SQUID this is seen as a periodic variation of critical current with magnetic flux. \; In the atomtronic SQUID it causes a periodic va riation of critical current with rotation\, enabling the device to functio n as a gyro. \; Second\, we are developing an atomtronic version of th e Fiber Optic Gyro\, in which rotation is measured by the Sagnac effect.&n bsp\; In our device a Bose-Einstein condensate is split\, reflected\, and recombined inside a waveguide that is translated so that the wavepackets t ravel around a loop and realize a waveguide Sagnac atom interferometer.&nb sp\;
