Electronic Circuit Schematic of Touch Sensor using NE555

Robometricschool. - Maybe for a long time we didn't post again about electronic circuit schematic in this blog. So in this time we want to try give you again my posting about electronic circuit schematic of Touch Sensor using NE555 Based Proteus Software Simulation.

Maybe it is simple electronic circuit schematic that can be implemented in touch sensor for many using. Why we said that it is simple circuit because this circuit only need little components and only need little semiconductor components like transistor and integrated circuit. And specially we need integrated circuit for this circuit using NE555.

We will show you the schematic of Touch Sensor using NE555 according simulation result from Proteus program that used to design circuit and simulation. And here are all of circuit schematic of Touch Sensor using NE555 using Proteus Software.

Circuit Schematic of Touch Sensor NE555

Component List:

When tell about of component that used in Touch Sensor using NE555, you can see from all schematic like in figure 1 and figure 2 above. Main semiconductor in this circuit is NE555 that very easy to get in many electronic component shop. 

Performance of Touch Sensor using NE555

Global performance of this circuit schematic of touch sensor using NE555 as follow:
  1. When we touch the plat from input it will make LED D1 will turn on and 
  2. When we don't touch plat from input,it will make LED D1 will turn off.
And when we discuss the performance from electronic circuit schematic, we can describe as follow:
  1. When we touch the plat as input touch sensor medium, it will make transistor Q2 active and make IC NE555 will active to drive Q1. It will make transistor Q1 work like switch on ( close ) and make Relay active to turn on the LED D1.
  2. When we don't touch plat as input sensor medium, it will make transistor Q2 not active and make IC NE555 will not active. Transistor Q1 will not active and make this transistor work like switch off (open) and make Relay not active, and LED D1 turn off.
So all performance of this electronic circuit schematic of touch sensor using NE555 so simple and we can know work of this circuit when we simulate this circuit like using Proteus software. So when you want to use Proteus software you can take free download this software according many version as follow:
  1. Download Proteus 7.1
  2. Download Proteus 7.2
