Linear Monostable Converts Capacitive Transducer Measurements into Pulse Train (.PDF Download)

May 4, 2021

Read this article online.

The circuit in Figure 1 allows you to convert capacitance into a pulse train by using a constant current source and a linear monostable formed by two NAND-gate chips (74HC132). The circuit also provides two pulses to control external counter functions such as Latch and Reset, which are normally required by digital counters and latches when driving a display. Applications for the monostable include instrumentation circuits when the need arises to convert a transducer’s capacitance measurement (such as relative humidity), into a pulse train.
