Comparison of pressure sensors with wireless transmission for IoT applications
A comparison of pressure sensors with wireless transmission capabilities for IoT applications will be on show. The pressure signals are read out via by an IC-integrated multiplexer, transmitted via Bluetooth, and recorded in real time in a continuous chart. This type of readout electronics in combination with miniaturized sensors makes it possible to measure physical quantities wirelessly in prototypes even in hard-to-reach places. Up to 10 different pressure sensors are used to demonstrate the differences between the sensors in terms of their sensitivity, hysteresis, and response time.
