Metering module and Timing module

Metering module

The metering module is composed of a multi-stage LCD device and an integrated circuit chip with decoding, driving, counting and a / D conversion functions. Because the integrated circuit has a / D conversion function, the input analog electrical signal can be converted into digital display. We know that any physical quantity, even chemical quantity (such as pH value, etc.) can be converted into analog electricity. As long as a certain sensor is equipped, this module can realize any amount of numerical value and display, which is very convenient to use.

Timing module

The timing module uses LCD device for the longest time in history. It is a kind of full function timer to assemble LCD with sequential integrated circuit. Because it has no finished case, it is called timing module. Although timing module is very rich in functions, it is difficult to buy universal and standard timing module in the market. You can only purchase or order the appropriate watch movements from the meter manufacturer. Although the appearance of timing module and counter module is similar, the display mode is different. The number displayed by the timing module consists of two digits and two digits. Each number of the counting module is arranged consecutively. Because many timing modules also have timing and control functions, such modules can be widely assembled on some powered devices, such as cassette recorders, CD players, microwave ovens, rice cookers and other electrical appliances.
