Present work deals with the development of a low cost, appreciably accurate and sensitive electronic circuit for resistive sensor. The circuit is based on the modification of the Wheatstone bridge using active devices. It helps measurement of the incremental resistance precisely and linearly. It requires few components for its hardware implementation and found to be suitable in case there is small change in resistance due to change in physical quantity or chemical analytes to be measured.doaj:ea1befff948d4a388c95f56f26e222b8 fatcat:kvabkh4zunbhjfccx4rqfdpb4q
