Using AKKR8 for Monitoring Indoor Air Quality
AKKR8 has embedded sensors for measuring various air quality related parameters, in short AQ. It has an integrated ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor to detect a wide range of Volatile Organic Compounds (VOCs) for indoor air quality monitoring. The air quality sensor is based on a micro-hotplate technology which enables a highly reliable solution for gas sensors, very fast cycle times and a significant reduction in average power consumption.
The built in sensor supports intelligent algorithms to process raw sensor measurements to output total VOC (eTVOC) and equivalent CO2 (eCO2) values, where the main cause of VOCs is from humans.
The built in AQ-sensor is optimized for low-power consumption and has an idle mode to extend battery life in portable applications. The AQ-sensor is designed for reliability and long lifetime.
The AQ sensor measures:
· eCO2 The equivalent CO2 (eCO2) output range for CCS811 is from 400ppm up to 32768ppm.
· eTVOC The equivalent Total Volatile Organic Compound (eTVOC) output range for CCS811 is from 0ppb up to 29206ppb.
Due to the nature of the sensor, it shortens the battery life time of the sensor. Thus we do recommend using this function using a power supply, if the intention is to measure often.
AKKR8 wakes up at predefined time intervals. The sensor can send every value to the server or be set to read the value, store it and go back to sleep if the value is below an acceptable limit. If the threshold is exceeded, the sensor will force the value to be sent immediately to the server.
