Sparkfun sells them but they were out of stock.\u00a0 I managed to find them on eBay for $8 each, plus they included the cable.\u00a0 Well, the cable included was wrong.\u00a0 The sensors take a 6 conductor 1.5mm spaced connector, they shipped me a 3 conductor 1.5mm spaced connector.\u00a0 I did a search online and found out some information about the pinning.\u00a0 This website<\/a> appears to have the wires soldered on the back end of the connector.\u00a0 Not sure if I really want to do that, seems kind of risky to the board.<\/p>\n To my relief, I found this website<\/a> that had a parts list.\u00a0 Lo and behold, that’s exactly what I need.\u00a0 Digikey sells them<\/a> for about $1.50 each.\u00a0 I’m going to scrap the idea of soldering wires in desperation.<\/p>\n Besides finding some details about the sensor, pinout, and cable to get, I found great references for code.\u00a0 It’s helpful to have some help along the way.\u00a0 With the cornucopia of sensors going into the helmet, having a clear understanding of the code is a must.\u00a0 It’s already going to be a challenge getting all of this stuff to fit in the helmet.\u00a0 On top of that, fitting the code into the Pro Mini will also be a feat yet to be done.<\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" The 3 GP2Y1010AU0F Compact Optical Dust Sensors arrived in the mail the other day.\u00a0 These are air quality sensors that use IR to detect\u00a0fine particles and smoke in the air.\u00a0 I’ll be using them with my sensor helmet to detect air pollution and plot the results on a map or overlay the readings on my action camera video.\u00a0 They are smaller than I envisioned.
