The utility model relates to a multiple dynamic measurement automatic recorder, which comprises a sensor 1, an outer shell 2, a printed circuit board 3, an amplifier, an analog-to-digital converter, a microcontroller and a program memory. Electronic elements such as a data memory, etc. are arranged on the printed circuit board 3, and the printed circuit board 3 is arranged in the outer shell 2. The utility model has the advantage that the microcontroller externally triggers a recorder by a single channel. One instrument is used for measuring one item of date, and one instrument cooperates with one sensor, therefore, the utility model does not need transmitting conducting wires. Furthermore, the utility model has the advantages of small size and simple operation. After the power supply is switched on, the utility model automatically carries out recording as long as a signal is detected, and the utility model automatically carries out power cut when recording is finished. No data is lost during the use of the utility model, therefore, the utility model obtains a favorable economic benefit in practice.
