This article describes the Temperature Measurement (Sensing) and Monitoring (TC9400). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:TC9400.

Temperature? measurement (sensing) and monitoring will be economical and straightforward if we apply the input of? TC9400 V/F converter with a voltage from output of a probe, such as shown in diagram below. The V/F output is simply counted to display the temperature. The TC9400 can be used to modulate an RF transmitter for a long distance data transmission.

TEMPERATURE METER circuit schematic


The temperature display should have latch control, means that the counting process is not transparently displayed on the seven segment until a latch signal is triggered to transfer the counting result to be displayed. After latched, the reset signal would reset the counter without affecting the latched display.
