With capacitors, the smaller the capacitor, the larger the impedance (known as capacitive reactance). It''s a little tricky, because it''s the opposite of how resistors behave, but keeping this twist in mind, the rest is straightforward. When two capacitors are in series, the largest voltage will develop across the smallest capacitor. In the
Capacitive sensors can also detect liquids like water, oil, and paint. Some capacitive sensors can be used to detect material inside a nonmetallic container.

Generally, a capacitor sensor is one type of proximity sensor used to detect nearby objects through their electrical field effect formed through the sensor. These types of sensors have some similarities with radar in their capacity to sense conductive materials while observing through insulating materials like plastic or wood.
The liquids which can be detected by a capacitor sensor are oil, paint, water, etc. A capacitive sensor works like a normal capacitor. In this sensor, a metal plate within the sensing face is electrically connected to an oscillator circuit and the target which is detected can act as the next plate of the capacitor.
Any target that can disrupt this electrical field can be detected by a capacitive sensor. Some examples of the solid materials a capacitive sensor can detect are all types of metal, all types of plastic, wood, paper, glass, and cloth. Capacitive sensors can also detect liquids like water, oil, and paint.
A simple capacitive sensor has been available commercially for many years for the detection of nonmetallic objects, although they are restricted to short ranges, normally below 1 cm. Generally, a capacitor sensor is one type of proximity sensor used to detect nearby objects through their electrical field effect formed through the sensor.
Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens). Size and spacing of the capacitive sensor are both very important to the sensor's performance.
