Smart Dispenser: Dispenses solutions based on the VOC
By Dan Chen, September 28, 2017
In this experiment we are dispensing mouthwash, but you can dispense any solution that you like base off your sensor data. This is a close loop control system where the output is based on the sensor data.
In this example, bad breath can be measured via volatile sulfur sensor, however but we are using the TVOC sensor … it’s tracking all VOC compound but can not isolate bad breath compound, sulfur . This sensor will be sufficient for what we are doing. Imagine you can dispense water pairing with humidity sensor, this could give you the right amount of water based on how dry your mouth is … I am not totally sure the science behind this, it’s just an example.
