Abstract Uses STM32 processor as the core processor, the digital signal outputted from BMP085 sensor as input, the Atmospheric Pressure transmitter can enlarge the analog signal converted from STM32 D/A by operational amplifier LM321, and it can use the XTR111 V/I conversion chip which has an output of 4~20mA.

Key words： single chip microcomputer transmitter atmospheric pressure sensor operational amplifier V/I Converter
