The open sensor structure and its conditioning circuit can enhance the students' understanding of the basic knowledge, in the course of the experiment through the signal picking, conversion, analysis, training students basic operational skills and practical ability, as well as analysis and problem solving ability.

The main laboratory test platform by the sensor test board (power supply + 5V, +12 V input and output interface, protection module, breadboard, instrumentation amplifier, PWM control output), switching power supply and related experimental components (sensors, Components, light source components, operational amplifiers, resistors, capacitors and other components), the basic sensor circuit design analysis, the typical sensor structure and principle, sensor signal interface, amplification, filtering, linearization, sensor applications and other experiments. And can be combined with DRVI fast reconfigurable virtual instrument platform, data acquisition instrument, to complete the signal analysis and signal processing simulation experiments.
