Automatic Room light Control With Bi Directional Visitor Counter
The objective of this project is to create a controller-based model that counts the number of individuals entering a specific room and activates the lighting accordingly. This is achieved through the use of sensors that detect the current number of...
ProfiLab-Expert 4.0
The ProfiLab-Expert software allows you to develop your own digital or analogue measuring technology projects. It doesn't matter if you want to create analogue measurements or digital controls - you can realize it all. And for all this you don't...
RealView 2.0
RealView is a measurement application, which records and plots measured values from analogue hardware devices in real-time. Several curves can be plotted into a single diagram. Several diagrams can be arranged on one or more pages if necessary. Plot options...
Field disturbance sensor-alarm
The change in ambient light triggers the alarm by changing the resistance of LDR1 and LDR2.
The circuit utilizes two light-dependent resistors (LDR1 and LDR2) to detect variations in ambient light levels. LDRs are passive components that exhibit a change in...
Blanket internal measurement circuit disconnection
The internal disconnection circuit for a blanket operates on the principle of induction. It includes a wire approximately 2 cm in length that senses the proximity of a charged mains power source. When the sensing wire is close to the...
Sensor-Activated Relay Pulser Circuit
A sensor activates transistor Q1 to turn on the low-frequency 555 oscillator, which generates pulses to control LAMP II. The sensor may respond to variations in light or temperature. Either resistor RA or RB can function as the sensor, depending...

Detector And Controller
Many applications require analog signals to be sensed and digital signals to be controlled. A way to detect these points is by using a 555 timer in an unconventional configuration. This method will also add hysteresis to the circuit and...
make electromagnetic field
This circuit is a valuable tool that is easy to construct and more sensitive than many commercially available devices. It is based on an LF351 low-noise operational amplifier and a 1mF choke functioning as the sensor. Unlike most simple EMF...
