Water pollution sensor based on photodiodes

In cooperation with our partners we have developed in our laboratories concept of a sensor measuring the degree of water pollution. With these considerations, the design took into account the use of a sensor for sensing contamination associated with the development of micro-organisms such as fungi and molds, and plankton and microorganisms such as protozoa.

The use of this device can be found in home and commercial pools as well as in breeding ponds.

Sensor calibration involves the determination of the resistance of the base for photo resistor with known emission light source emitter. Loss of sample to a marked decrease of resistance indicates the degree of pollution and thus increase transparency. However, the greater the resistance represents a decrease of transparency, and therefore an increase in pollution.

The working prototype has been prepared and now wait for the final implementation.
