This paper presents a data recording device that can directly measure temperature and pressure. The device consists of isolation diaphragm digital output pressure sensor, low power consumption microcontroller, EEPROM chip and a few peripheral devices. Through the ASIC, temperature and pressure simulation Data to digital data conversion, under the control of the microcontroller, temperature and pressure measurements and records. The device has the advantages of simple structure and small size, and is suitable for a lot of places that need to test the pressure.
