Optical Dust Sensor
We will measure the dust density in the atmosphere (in mg/m3) both at the launch campaign in Norway and in our region, as well. We'll do that using an optical dust sensor (like Sharp's GP2Y1010AU0F sensor). This sensor uses some laws of optics, more precisely the phenomenon of reflection. A phototransistor and an infrared emitting diode are diagonally arranged into this device in order to allow it to detect the reflected light of dust in air (photometrical analysis). It is very effective in detecting very fine particles and in addition it can distinguish smoke from house dust by pulse pattern of output voltage.The sensor has a very low current consumption (20 mA max, 11 mA typical). The output of this sensor is an analog voltage proportional to the measured dust density, with a sensitivity of
0.5 V/0.1 mg/m3.
Salut si felicitari pentru proiect!
ReplyDeleteDeoarece am vazut ca folositi senzorul de praf Sharp pe care tocmai l-am achizitionat si eu, vreau sa va intreb cum ati rezolvat problema conectorului minuscul JST. Ati lipit manual pinii pe fire sau ati sertizat un conector-mama?
Am folosit un conector-mama si circuitul care este inclus in "data sheet"-ul senzorului. Daca poti sa-mi dai o adresa e-mail o sa-ti trimit niste poze.
