Description: Cociclo is a Carbon Monoxyde (CO), temperature and humidity sensor and logger based on the ESP8266 wifi chip. It uses a Wemos programmed with Arduino. It interfaces to a MYSQL database and makes use of the D3.js and P5.js javascript libraries for data visualisation.  Another version of the code turns the air pollution into noise pollution. http://cociclo.io
