Up to 61 SDI-12 sensors can be connected to the same pin of the Mayfly. It is more stable to use the same pin for all the SDI-12 sensors you wish to connect rather than using different pins for each because this allows you to create only one instance of the SDI-12 object in your code. To connect multiple sensors to that pin, you can use a Grove branch cable (https://www.seeedstudio.com/Grove-Branch-Cable-%285PCs-pack%29-p-847.html) or a Grove hub (https://www.seeedstudio.com/Grove-I2C-Hub-p-851.html).
