一种多通道温湿度传感器选通控制器的研制

Development of a Multi-channel temperature and Humidity sensor Gating Controller

根据实验室温、湿度传感器校准的业务需求,以及自动气象站现场校准工作需要,研制了一款便携、操作简易且可用于户外工作的多路温、湿度传感器通道选择控制器。控制器具有8路4线制温度传感器选择通道、2路湿度传感器选择通道,具有人机交互界面,同时可以通过串口进行控制,支持通道自动、手动切换。该模块的业务化大大提高了温湿度传感器的校准、检测效率,只需一台测试设备,即可完成多路传感器的测量。

According to the business requirements of laboratory temperature and humidity sensor calibration and the needs for onsitecalibration work of automatic weather station, a multi-channel temperature and humidity sensor channel selection controllerwhich is portable, easy to operate and can be used for outdoor work has been developed. The controller has eight 4-wire temperaturesensor selection channels and two humidity sensor selection channels with man-machine interface. At the same time, it can be controlledthrough the serial port supporting automatic and manual switching. The module greatly improved the temperature and humiditysensor calibration, detection efficiency in business, and only one test equipment can complete the measurement of multi-channelsensor.
