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...
Analog Mains Frequency Meter
Mains frequency is pretty stable and it is unlikely that you have to measure it but if you have an emergency generator you might find this circuit useful as it will give an indication whether the generator is running too...
pH METER
The Beckman model W industrial-type pH meter is a direct current (DC) amplifier designed for measuring the potentials generated by pH-sensitive electrodes. The output is capable of driving most recorders. Resistor R32 is utilized exclusively with the 4 to 14...
Advances in Measurement & Sensor Tech
This issue features articles on various measurement and sensor-related embedded design projects. Readers are encouraged to attempt similar projects and share their results. Starting on page 14, Petre Tzvetanov Petrov describes a multilevel audible logical probe design. Petrov notes that...
Instrumentation circuit
The mechanical chassis prototype, as illustrated in the accompanying image, was constructed using two materials: foam and aluminum. Foam was selected for its ease of manipulation, while aluminum was chosen for its excellent strength-to-weight ratio. The prototype features a rotary...
Analog Equaliser
The time constant of R1C1 determines the low cutoff frequency, while the time constant of R2C2 determines the high cutoff frequency. The pass-band gain, Avpass = R2/R1. For a high-pass filter, Za must be capacitors and Zb resistors. By substituting...
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...

Constantly changing light and sound analog controller circuit 04
The circuit designated as the "Constantly Changing Light and Sound Analog Controller Circuit 04" is designed to modulate both light and sound outputs in a dynamic manner. This type of circuit...
Pots water alarm circuit
The flowers in pots require watering, as relying solely on the observation of moist soil surfaces can be unreliable. To address this issue, a flower watering indicator has been developed. This circuit includes a field effect transistor (VT1), a second...
