TOPTEN AS01 is a gas alcohol sensor. Using a multilayer thick film manufacturing process, a
heater and a metal oxide semiconductor gas-sensitive layer are formed on both sides of a micro
Al2O3 ceramic substrate, which are led out by electrode leads and packaged by a TO-5 metal
casing. When the detected gas exists in the ambient air, the conductivity of the sensor changes.
The higher the concentration of the gas, the higher the conductivity of the sensor. Through the
LCD screen and automatic broadcast of the machine, to test of the alcohol concentration of the
driver and the safe driving of the vehicle.
I: Features:
1. Low power consumption
2. LCD display to show the alcohol level
3. Automatic broadcast
4. Mini size
5. High sensitivity to low-concentration pollutant gases
6. Easy installation
II: How it works
1. DUI(Driving under the influence): default level 90 mg/L
When the sensor detect the level high than 90 mg/L, it will trigger alarm, the sensor will
broadcast:"Warning! Alcohol level is high, it is danger to drive", if the driver keep there and
alcohol keep more than 90mg/L, it will broadcast every 5min. In this mode, the sensor just keep
broadcast to tell the driver its drunk driving, do not trigger other alarm.
2. Drunken Driving: default level 363 mg/L
When the sensor detect the level high than 363 mg/L, it will trigger drunken driving alarm,
the siren make "BIBI" noise sound directly, meanwhile, it will send out stop command to make
car cannot move as long as the car install the relay with alcohol sensor.
III: Set Up Process
Initialization Calibration Process
1. Keep the sensor power on for more than 10 minutes
2. Make sure the surrounding air is clean
3. Press and hold the bottom for more than 5 seconds (including 5) and then press 5 times.
4. The sensor beeps 5 times indicate that initialization was successful.
Threshold setting process (Default threshold is 363mg / L for national drunk driving)
1. Press the bottoms more than 8 times (including 8) and then hold for 8 seconds
2. The instrument's voice prompt "Setup Mode" means entering the setup option mode
and the displays flashed.
3. Press the bottom less than 2 times (including 0 and 2) within 3 seconds to enter the
setting threshold mode.
4. After entering the setting threshold mode for 1 second, you can set the threshold by
pressing the key: 218mg / L--503mg / L
5. If there is no operation for 10 seconds, the sensor will exit the setting mode auto. And
the voice prompts "Operation Mode".
Set the alcohol state maintenance time flow (Default is 5 seconds)
1. Press the bottoms more than 8 times (including 8) and then hold for 8 seconds
2. The instrument's voice prompt "Setup Mode" means entering the setup option mode
and the displays flashed.
3. Press the bottom more than 3 times (including 3) within 3 seconds to enter the alcohol
state time mode.
4. One second after entering the alcohol state time mode, it can set the threshold by
pressing the key, rang 0-30 seconds
5. If there is no operation for 10 seconds, the sensor will exit the setting mode auto. And
the voice prompts "Operation Mode".
