Abstract: A method for determining a position of a device includes: providing position detection pins on Bluetooth slave modules, and when the Bluetooth slave modules are installed, connecting the position detection pins of the Bluetooth slave modules at different installation positions to different level signal pins such that the level situations of the position detection pins of different Bluetooth slave modules are different; and comparing by a Bluetooth master module or the Bluetooth slave modules the level situations of the position detection pins of the Bluetooth slave modules with a pre-stored position level table, and identifying installation position information corresponding to the Bluetooth slave modules, and determining a position of the target device based on the signal strength value sent by each of the plurality of Bluetooth slave modules and the installation position of each of the plurality of Bluetooth slave modules.
