Switch sensor insertion detection device and software detection method

A switch sensor insertion detection device relates to the technical field of sensors, and is characterized in that a feedback signal line is pulled up to a high level through a resistor R2, so that when a sensor is not inserted, a signal of the feedback signal line detected by an I0 port of a single-chip microcomputer is in a high level, and when the sensor is inserted, the signal of the feedback signal line detected by the I0 port of the single-chip microcomputer is in a low level; the sensor insertion judgment can be realized, the stability of the equipment is improved, and the use mode and application scene of the equipment are expanded. 一种开关传感器插入检测的装置，涉及传感器技术领域，反馈信号线通过电阻R2上拉到高电平，因此传感器未插入时，单片机I0口检测到反馈信号线信号为高电平，当传感器插入时，单片机I0口检测到反馈信号线信号为低电平，可以实现对传感器插入的判断，提高设备的稳定性，扩展设备的使用方式与应用场景。
