Application Guide for Sharp GP2Y1026AU0F Dust Sensor
5. Airflow design recommendation
The GP2Y1026AU0F dust sensor does not include any built-in fan or internal resistor
heating element to supply airflow to the sensor (and note that the specification does not
indicate any airflow is required). While this can be advantageous in terms of providing
flexibility in sensor orientation and positioning, it is recommended in practice to design in
at least some airflow into your application so that the sensor can react quicker to changes
in dust concentration and thereby provide more accurate results. For example, if your
application is an air purifier or an air conditioner, you might be able to use the system's
natural airflow for this purpose. Otherwise, you can look at adding a mini 20x20mm or
25x25mm external fan. It is also advisable to use a coarse mesh filter in your application
design to prevent large dust particles from entering the Sharp sensor and accumulating
inside. While a light vacuum can be used to remove large dust pieces which may be
attached inside the sensor, your application design may preclude such kind of
maintenance access to the sensor.
6. GP2Y1026AU0F connector cable
Sharp GP2Y1026AU0F uses the same type of 6-pin connector as the GP2Y1010AU0F model.
Earlier iterations of the GP2Y1010AU0F sensor used the JST (Japan Solderless Terminal)
connector S6B-ZR-SM4A. But all newer production versions of both sensors now use JCTC
connector 11501W90-6P-S-HF which should be compatible with the old JST connector.
What this all means is if you have an old cable harness for GP2Y1010AU0F, the cable
should work just fine with GP2Y1026AU0F as well. The following table and figure shows
the pin assignments for GP2Y1026AU0F.
