I got two SEN55s (240-9022) from Sensirion, so I connected one to an Arduino MKR1010 board. My goal was to determine how easily the sensor could be integrated into a board design that communicates with the sensor through the I2C interface. Additionally, I connected the sensor using the sensor bridge and the control-center software provided by Sensirion. This method of reading data from the sensor was very easy to set up and allowed me to compare the data I received from the Arduino serial terminal to what the sensor bridge was reading from the sensor. Sensirion also provided a useful guide and sample code on how to obtain readings from an Arduino board (see link below). Overall, working with the SEN55 has been very easy.
