(SKU:SEN060008)AM2320 I2C IIC数字湿度传感器
来自YwRobot Studio Wiki
简介
电容式温湿度传感器模块AM2320是一款含有己校准数字信号输出的温湿度复合型传感器。采用专用的温湿度采集技术，确保产品具有极高的可靠性与卓越的长期稳定性。传感器包括一个电容式感湿元件和一个高精度集成测温元件，并与一个高性能微处理器相连接。该产品具有品质卓越、超快响应、抗干扰能力强、性价比极高等优点。 电容式温湿度传感器模块AM2320通信方式采用单总线、标准I2C两种通信方式。标准单总线接口，使系统集成变得简易快捷。超小的体积、极低的功耗，信号传输距离可达20米以上，使其成为各类应用甚至最为苛刻的应用场合的选择。I2C通信方式采用标准的通信时序，用户可直接挂在I2C通信总线上，无需额外布线，使用简单。两种通信方式都采用直接输出经温度补偿后的湿度、温度及校验CRC等数字信息，用户无需对数字输出进行二次计算，也无需要对湿度进行温度补偿，便可得到准确的温湿度信息。
