## Choosing Sensors Often the first step is to look for a sensor for what you're hoping to measure. Below we're collecting info on different kinds of water quality sensors, and their: * cost * sensitivity/accuracy * links and documentation Can you afford a sensor? Can it detect what you're looking for? Where can you learn more about it? **** https://publiclab.org/w/pm-monitoring#Regulatory+grade+PM+monitoring (this section under construction) Drivers for Arduino + Raspberry Pi are available for the following devices: * ThermoFisher PDR 1500 - #11927 * Dylos - #dylos & #11927 * Shinyei particle sensor - #shinyei & #11927 * [DustDuino](/dustduino) (using the Shinyei) **** ## Questions [questions:air-sensors]
