随着科学技术的发展,对于同时检测多路参数的需求日益增加。文章介绍的8路电压表,可测量0～5V范围内的8路电压值。在实际应用中,可以通过传感器进行八路模拟量的测量,如温度、湿度等环境参数或体温、血氧饱和度等生理参数。也可以实现远程测量结果传送等扩展功能。 With the development of science and technology, there is an increasing demand for simultaneous detection of multiple parameters. The article describes the eight voltmeter can measure the range of 0 ~ 5V 8-way voltage value. In practical applications, the sensor can be eight-way analog measurements, such as temperature, humidity and other environmental parameters or body temperature, oxygen saturation and other physiological parameters. Extended measurement results can also be sent to other extended functions.
