Objective Option 1 -
In the spirit of hacking parts together to not create more waste to create a sensor system that can be portable and sensitive enough to get accurate results from the field either in close proximity or form a safe distance.
To use recycled parts hacked together to make a handheld air quality Sensor instrument and the use of a node that can be deployed wireless from a safe distance. Measuring can be done from either the proximity of the device or from the wireless node sensor.
Objective Option 2 -
Still using some recycled parts however new sensors have been used to preserve accuracy and all other parts that can be hacked are used instead.
