This is a 8MHZ Crystal. This is a low cost crystal oscillator with oscillation frequency of 8Mhz. Crystal are normally required to provide clock pulses to your micro controller or other IC’s which require external clock source.
An oscillator crystal has two electrically conductive plates, with a slice or tuning fork of quartz crystal sandwiched between them. The crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. Quartz has the further advantage that its elastic constants and its size change in such a way that the frequency dependence on temperature can be very low.

This DC Voltage Sensor Module is essentially a 5:1 potential divider circuit built using precession resistors for high accuracy.
The Arduino analog input is limited to a 5 VDC input. If you wish to measure higher voltages,this module allows you to measure voltages of 0-25V. Keep in mind, you are restricted to voltages that are less than 25 volts. More than that and you will exceed the voltage limit of your Arduino input.
