10 Sensors
10.1 Analog input
The dust monitor has 3 analog inputs at the 6 pin socket. This is located on the inner side of the
connection module in the sample holder 181. It can be connected to any suitable analog sensor with an
output voltage between 0 and 10 Volts. The connection socket can also provide the external voltag of +10
Volts up to 40mA.
The analog sensors do not need an additional data storage. All measured analog values will be stored
onto the data storage card and sequentially being displayed on the display. The resolution is 10 Bits (ca.
10mV). Texts and factors for the LCD display can be changed.

10.2 Barometer (internal)
Inside the device is a barometric sensor. Its values its values will be stored and output as Ue4. The
display shows the value as Pressure.
10.3 Basic sensors
The sensors for ambient temperature and humidity are to be connected by default. They are necessary for
the proper operation.
