this library communicates with the T6603 GE/Telaire CO2 sensor. This sensor uses the Telaire Tsunami-Lite Commnications Protocol available functions are: get_status() return byte get_co2_ppm() return word -- CO2 concentration in ppm get_serial_numer() return string[15] get_elevation_m() return word -- in meters above sea level

set_co2_elevation_m(word in meters)
should set elevation in meters above sea level, not implemented yet
get_co2_serial_number(byte out str[8])
returns 8 byte ASCII string, which should be the same as the number on the sticker
get_co2_elevation_m() return word
returns programmed elevation above sea level in meters this elevation is uses to calculate CO2 concentration correctly
get_co2_ppm() return word
returns a word with CO2 concentration in ppm note: if sensor is busy measuring the CO2 values, it will give garbage reply reply is checked for garbage and if so, *PREVIOUS* ppm value is returned
get_co2_status() return byte
returns status byte. bit_0 = error, bit_1 = warmup, bit_2 = calibration, bit_3 = idle
