The idea of 37 sensors and modules has been widely circulated on the Internet. In fact, there must be more than 37 sensor modules compatible with Arduino. In view of the fact that I have accumulated some sensor and actuator modules on hand, according to the concept of true knowledge (must be hands-on), for the purpose of learning and communication, I am going to try and do more experiments one by one here, and I will record them whether I succeed or not.
