I am developing air quality measuring device which is included Grove dust sensor , grove humidity and temperature sensor. I am using a Grove Pi plus to connect these sensors to Raspberry pi. I am also using MQ135 ( No2 Click sensor) and MQ131( Ozone click sensor) , for connecting these latest sensors to Raspberry pi a Pi 3 click shield has been used. So far I have used two Raspberry pi 's for these two groups of sensors. Since Grove Pi plus has 26 pins and Pi3 click shield 40 pins, I am looking for a way to integrate all the sensors with one raspberry pi. Any expansion board or … ?
Otherwise, any information about How Pi3 Click shield maps the Raspberry pin?
Any suggestion/ solution regarding this would be greatly appreciated.
