本文介绍的 LED 通用电平显示器,利用10个发光二极管作为输入端电平变化的显示,输入端电平信号可以是通过各类传感器和变换电路而探测的各种物理量,如电压、电流、温度、湿度、亮度、响度、音频、距离、磁场强度、重量等等,用它做成的电平显示器,既醒目、直观。又方便、实用,并且能反映瞬间变化的信号,用途十分广泛。例如.在电路设计制作中,它既可以通过探头和处理电路实现温度控制和显示,用于烘箱、冰箱、空调、热塑封机等设备上,也可以通过分压变换电路实现电压高低的直观显示,用于仪器、仪表、音响及办公设备上。
This article describes the LED general-purpose level display, the use of 10 LED as the input level changes in the display, the input level signal can be detected by various sensors and transform the physical circuit, such as voltage, current, temperature , Humidity, brightness, loudness, audio, distance, magnetic field strength, weight, etc., made of it with a level display, both eye-catching and intuitive. And convenient, practical, and can reflect the signal of instantaneous changes, uses a very wide range. For example, in the circuit design, it can achieve temperature control and display through the probe and processing circuit, used in ovens, refrigerators, air conditioners, thermosensitive seals and other equipment, can also be achieved through the partial pressure conversion circuit voltage level visual display , For instruments, meters, audio and office equipment.
