There's a mention of the SEN5X here: https://github.com/MIT-Senseable-City-Lab/OSCS/blob/main/Bui...

The Readme file [1] on their GitHub repo contains this bill of materials: https://docs.google.com/spreadsheets/d/1-fR-0hTxHKbjaRf8DbH6... This lists a "particle module", a temperature sensor and some other seemingly irrelevant sensors (GPS, accelerometer). [1] https://github.com/MIT-Senseable-City-Lab/OSCS/tree/main/Bui... edit: looks like the "particle module" is just a LTE/BT communication module, so really there don't seem to be any environmental sensors other than for temperature.

Link to bill of materials: https://docs.google.com/spreadsheets/d/1-fR-0hTxHKbjaRf8DbH6... Naively searching for every lines of the bill of materials gives me around $300, with a handful of items being around $50 and everything else under $5. I'm sure a hobbyist could find the parts for cheaper, especially things like individuals connectors that I found for around $5. I've seen them go as low as $0.25 when bulk purchased. Disclaimer: it's possible that some SKUs led me to the wrong products. I am not into electronics. I encourage you do to the same exercise before drawing conclusions.
