Example

--Note: due to the use of sys.wait() all apis need to be used in the coroutine
-- Usage Examples
sys = require("sys")
local ch2o = require "ze08g_ch2o"
local uartid = 1 -- According to the actual equipment to select different uartid

sys.taskInit(function ()
    local result = ch2o.init(uartid)
    if not result then return end

    while true do
        sys.wait(1000)
        log.info("Gas concentration value PPB：", ch2o.getPPB())
        log.info("ppm concentration PPM：", ch2o.getPPM())
    end
end)
