A photoresistor (or light-dependent resistor, LDR, or photoconductivecell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive d..
A photodiode is a semiconductor device that converts light into an electrical current.
The current is generated when photons are absorbed in the photodiode. A
small amount of current is also produced when no light is present.
Photodiodes may contain optical filters,
built-in lenses, and may hav..
A piezoelectric transducer has very high DC output impedance and can be modeled as a proportional voltage source and filter network. The voltage V at the source is directly proportional to the applied force, pressure, or strain. The output signal is then related to this mechanical force as if it had..
