Abstract

The application discloses a method, a device, equipment and a storage medium for collecting sensor signals, which belong to the field of communication and are used for collecting signals emitted by a sensor. Considering that the lower limit value of the signal intensity of the signal which can be received by the receiving device is higher in general, namely, when the sensor sends out a signal with weaker intensity due to insufficient power supply voltage, the signal can not be received by the receiving device, so that the application can firstly determine the lowest value of the signal intensity of the signal which can be received by the receiving device and is transmitted by the target sensor, and then adjust the minimum signal intensity of the signal which can be received by the receiving device and is transmitted by the target sensor according to the lowest value of the signal intensity, thereby being beneficial to the lower limit of the signal intensity of the signal which can be received by the receiving device, leading the receiving device to be capable of receiving the signal sent by the sensor when the power supply voltage is lower, increasing the duration time of the sensor, reducing the replacement frequency of the sensor and improving the user experience.
