Description
The P-NUCLEO-IKA02A1 evaluation pack
provides a reference design for various
electrochemical sensors.
The STM32 Nucleo gas expansion board
interfaces electrochemical sensors with the MCU
on the STM32 Nucleo development board. Two
TSU111 operational amplifiers provide signal
conditioning; they are ideal for electrochemical
sensing thanks to their high precision and low
power consumption. The expansion board
includes an ultra-low current precision analog
temperature sensor STLM20 used for
compensation of gas readings.
STM32 Nucleo boards provide an affordable and
flexible way for users to experiment with new
ideas and build prototypes with any STM32
microcontroller line. The NUCLEO-L053R8 is
designed for low power applications.
The design and componentry are optimised for
battery operation and maximum battery life time.
