| Abstract: | Digital temperature sensor can export temperature information of digital pulsing signal,and has the advantages such as higher measurement accuracy,better ability of anti-interference,farther transmission distance and simpler peripheral interface circuit. Especially, the digital export signal can send into the microprocessor directly, it has simplified greatly the hardware interface between the sensor and the microprocessor. Taking digital temperature sensor TMP04 as an example, which export mode is PWM,we design some kinds of temperature measurement schemes which was implemented by PIC single chip, and have actualized the measurement of temperature using simple circuit and program. |
