Multichannel U disk storage temperature monitoring device

The utility model discloses a multiple-channel U disk storage temperature monitoring device, comprising a plurality of temperature sensors, wherein, the output terminal of each temperature sensor is connected with a transmitter, the output of the transmitter is sent to a sample circuit and then is sent to a multiplexer after sampled by the sample circuit, the output of the multiplexer which completes the digital-to-analog conversion by an A/D converter is sent to a singlechip, the sensor data is stored into a memory by the singlechip or is stored into a U disk through a USB interface, a keyboard and a clock circuit as well as an LCD displayer are respectively connected with the singlechip. The utility model adopts the U disk as the storage medium; therefore, the cost is low, the storage capacity is huge, the data can be conveniently exchanged with the computer, the manipulation is convenient and simple and accords with the operation habits of users, and the problem that the prior temperature recorder must be directly connected with the download data of the computer is solved.
