Description

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

Procedures

Functions

  • 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
