Photovoltaic transducers has been widely used in medical, consumer, scientific instrumentation, and industrial applications. Photovoltaic sensors is a solid-state devices and available for wide range of wavelength response, cover from infrared, visible, and ultraviolet spectrum. This characteristic make this type of transducer applicable in diverse jobs such as colorimetry, chemical spectral analysis, non-contact thermometry, non-invasive [...]

Building electronic circuit tutorial (DIY: do it yourself project) is presented in this video. You can learn the basics about schematics and how they are used in electronics in this free home maintenance video.

To obtain an accurate pressure value, we must remove the offset errors. There are  many basic circuit designs that is used to remove the offset errors. This  circuit uses three method to remove the offsets errors, they are symmetrical offset trim, asymmetrical offset trim and amplifier gain adjustment. Here is the circuit: [...]

How to solder a resistor to PCB is presented in this video tutorial, get expert tips and advice from an expert on how to solder electronic equipment in this free instructional video. Expert: Jeff Nayl…

Introduction Interfacing humidity sensor can be difficult because of the sensor’s drive requirement and their wide dynamic range.  We can customize the circuit to obtain reasonable accuracy within the chosen range by carefully selecting the devices that comprise the analog front end. Here  we present a case study to design analog signal conditioner for [...]

This is pressure sensor signal conditioning circuit. It is simple and inexpensive circuit because it has small geometry and simple pressure sensor. It just uses a single Operational Amplifier. This circuit obtain power from from 3-V battery. To work properly this circuit must work in  0 C to 50 C temperature range. Here is the [...]
