使用交流电源和电池给远程湿度传感器供电是不可取的,因为如果你把远程湿度传感器安装在不易接近的地方,如烟囱、冷藏室或暗房,则这些电源由于难以维护而会令人烦恼。图1示出了一种可从湿度传感器电路中去掉电源的简单方法。湿度传感器电路使用了一个HumireI公司生产的 Using AC power and batteries to power the remote humidity sensor is not advisable because if you mount the remote humidity sensor inaccessible places such as chimneys, freezers, or darkrooms, these power supplies can be annoying due to the difficulty of maintaining them. Figure 1 shows a simple way to remove power from the humidity sensor circuit. Humidity sensor circuit using a HumireI company
