响应时间:≤1min BNC接口型pH传感器 PH2.0接口(3脚贴片) 增益调节电位器 电源指示灯 pH电极特性 电极输出为毫伏级,与pH值的关系如下(25℃): 连接图 使用步骤 注意: 请使用外接开关电源,使电压尽量接近+5.00V,电压越准,精度越高! 电极在每次连续使用前均需要使用标准缓冲溶液进行校正,为取得更正确的结果,环...
37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都
