Hi all!
I would like to meet makers interested in building / using sensors for testing soil, water and air quality in the city. (and link them to interesting data visualisation tools.)
I am also looking for accessible visual protocols to test elements like heavy metals in soil (Cu, Zn, Cr, Pb, Fe, As…), or gases in the Air, which do not require expensive equipment.
I am planning some workshops with gardeners, who have allotment gardens to build and their own devices/ sensors. (first one late August at Culpeper Gardens then in Leyton and Wlathamstow.)
If you know of anyone who is making such devices or is interested, do get in touch!
best
Thomas
