Based on single-chip microcomputer temperature and humidity data acquisition system design

In the actural production of life in many cases are to consider the influence of temperature and humidity environment and precise control, Then came the data acquisition system. Because the CAN bus can improve anti-jamming ability and reliability of the data, corrective ability etc. Therefore, use the CAN bus interface to transfer data then monitored by the upper machine. This article introduced data acquisition system design composed of temperature and humidity sensor, the SCM system, computer, the can bus. After SHT75 digital temperature and humidity sensors collect the temperature and humidity measurement data in warehouse room, to send data to C8051F060 SCM system through the bus interface.C8051F060 SCM do simple rapid processing of data through the CAN bus interface to the computer for real-time monitoring. Through testing, the system can realize data acquisition, processing and communication.
