Research project
A very cost effective sensor based on PCB coils has been developed. The electronic circuit of the sensor contains a driver circuit and an amplifier circuit. The sensor data is analyzed by a STM32 MCU and sent to a Raspberry Pi via UART.
Background Linear and rotary position sensors play an important role in automation and robotics. Inductive sensors are very robust, accurate and reliable because they consist only of wound coils and metal parts. On the other hand, they are also very large, expensive, and heavy. The amount of metal and the need to carefully wind the coils are the main reasons why they are expensive to manufacture. To overcome these disadvantages, such a sensor was developed based on printed circuit board (PCB) coils. A PCB-based rotary sensor can be optimized in terms of size and manufactured very cost-effectively.
