Design and Testing of a LowCost Sensor and Sampling ...

Americans spend most of their time indoors at home, but comprehensive characterization of inhome air pollution is limited by the cost and size of referencequality monitors. We assembled small "Home Health Boxes" (HHBs) to measure indoor PM , PM 10, CO 2, CO, NO 2, and O 3 concentrations using filter samplers and lowcost sensors. Nine HHBs ...


Building Pickle Jr. – the lowcost networked monitor ...

20141214 · However, the T2 is kinda expensive and I wanted to see if the same fan idea would work with the cheaper sensors, the PPD42 in particular. As a result, I built the Pickle Jr – which is the 42 with the fan connected to the same Arduino Ethernet I used …


LowCost PM Sensor Tutorial

2021910 · Part 1: Downloading Sample Data. To illustrate how to work with lowcost PM sensor data, we will take advantage of a large, established network: tutorial will consider some sensors deployed in the Greater Vancouver Area, but this code could be easily adopted to different PurpleAir sensors by adjusting the sensor identifier.
