A relay is represented in a schematic diagram as shown in this sketch. The relay is usually given a short name which is placed beside the coil. In this case the CR stands for Control Relay. It's contacts can be named as well and they are given the same name with sequential numbers also added. The top contact, CR-1, is a normally open contact.

Your circuit may produce slightly different results. Multiply the number of pulses counted at the “0” output by 10 to obtain the number of cycles produced by the 555 timer during that same time (my circuit: 79 x 10 = 790 cycles). Divide this number by 60 to obtain the number of timer cycles elapsed in each second (my circuit: 790/60 = 13.17).

The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element.Derivatives provide two or four timing circuits in one package.Introduced in 1972 by Signetics, the 555 is still in widespread use due to its low price, ease of use, and stability.

You can also vary 555 timer output frequency by changing the capacitor in the tank circuit, or create more complicated oscillator circuits.No matter which cap-based method you use, the supporting electronics have to be located near the sensor – because just about any length of wire will add enough stray capacitance to throw off your measurements. . Another thing to keep in mind is that .

A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator, a crystal, as its frequency-determining element. Crystal is the common term used in electronics for the frequency-determining component, a wafer of quartz crystal or ceramic with electrodes connected to it. A more accurate term for it is piezoelectric resonator.
