ADS-SMOKE-230 | Smoke sensor 230V
ADS-SMOKE-230 is used to control ventilation, air quality monitoring in
people-occupied areas like restaurants, shops, offices, households, flats, and
likewise.
- sensitive to cigarette smoke
- based on the electrochemical principle
- analog output 0 – 10V + output relay
- built-in regulator
- long-life
Description:
ADS-SMOKE is an indoor air quality sensor with analog voltage output 0-10 V and an output relay with an adjustable switching level. The sensor has a high sensitivity to low concentrations of pollutant gasses in the air. For example, carbon monoxide and hydrogen, are contained in cigarette smoke. Therefore is the ADS-SMOKE appropriate for use in areas polluted by cigarette smoke. Monitoring of air pollution allows very economically controlling of ventilation systems. The sensor is also suitable for tentative detection of alcohol vapors, methane/propane-butane/natural gas leaks. It can also detect organic vapors in restrooms, vapors from cleaning products and cosmetics (deodorants, perfumes, etc.).
The sensor is based on a semiconductor sensing element. It increases its
conductivity independence on the smoke in the air concentration. Built-in
electronics convert the input conductivity changes to the 0-10V analog output.
If you ventilate only when it is really needed, then is it possible to keep
the power consumption at a minimum.

- For long-term stability, it is recommended to power the sensor continuously.
- Since power on to warm-up the sensor. For the first 10 minutes, the output will be 0V. The relay starts to switch after this interval. In the next 24 hours, the sensor will stabilize.
Indicative sensitivity characteristics:
Front view:
Relay switching level adjustment wheel:
- turn to the left to decrease the relay switching level, the relay will switch at a lower air contamination level
- turn to the right to increase the relay switching level, the relay will switch at a higher air contamination level To avoid fast relay switching around the adjusted level the hysteresis of 1,5 VDC – related to the 0-10VDC output – is automatically added and the minimal duration of one state (contacts open/closed) is 1 minute.
LED indicator:
Blue
- continuous light = relay contacts closed
- blinking = relay contacts opened
Yellow
- Indicates only when you turn the adjustment wheel. After finishing the adjustment it indicates further 10s, after that the indicator turns off.
- Slow blinking – if you turn the wheel to left = more frequent relay switching.
- Fast blinking – if you turn the wheel around the middle = to set the standard air quality.
- Continuous light – if you turn the wheel to right = less frequent relay switching.
Terminals:
Connection example:
Jumper JP8 settings:
- Auto point – If fitted, the current measured
- the value will be saved as the calibration value.
- The new value will be saved ONLY when it
- is better (cleaner air) than the old value.
On the PCB jumpers location: 
- LED enable – if fitted, the blue LED
- indication is enabled.
-
Positions no. 3 and 4 aren´t intended for user settings
- don´t change settings on these positions!
Jumper JP1 voltage/current output setting:
Jumper in position 1-2 = voltage output.
Jumper in position 2-3 = current output.
Jumper JP2 current output setting:
JP2 fitted = output current range 4-20mA.
JP2 not fitted = output current range 0-20mA.
