Power is supplied entirely from your mobile device via the micro-USB or Lightning port.
Power consumption ranges from 30mA for steady state to 90mA during warm up, which is only 7 seconds. This consumption is negligible for short periods of time on any mobile device.
(For example: A Samsung Galaxy S4 battery is 2200 mAh)
We’re using a low-cost advanced stability semiconductor-based sensor.
Our innovative air inlet is designed to direct flow perfectly over the sensor such that readings are precise and repeatable. The inlet also works to slow airflow that is too fast, which allows for a greater range of breath air speed.
Air outlets are positioned so that alcohol can quickly clear the sensor area once a reading is taken.
Accuracy is approximately +/- 0.01% BAC at a BAC of 0.02%.
The sensor’s maximum BAC is 0.20% BAC. After that you’d probably need help standing anyway!
Accuracy was validated using testing and calibration kits from Lifeloc Technologies, the leader in breathalyzer testing and calibration.
