Example

--Note: due to the use of sys.wait() all apis need to be used in the coroutine
-- Usage Examples
sys = require("sys")
local zh07 = require "zh07"
local uartid = 1 -- According to the actual equipment to select different uartid

sys.taskInit(function ()
    local result = zh07.init(uartid)
    if not result then return end

    while true do
        sys.wait(1000)
        log.info(string.format("pm1.0  %sμg/m³", zh07.getPM_1()))
        log.info(string.format("pm2.5  %sμg/m³", zh07.getPM_2_5()))
        log.info(string.format("pm10   %sμg/m³", zh07.getPM_10()))
    end
end)
