求购CC2430+SHT11温湿度采集程序

[ggfysj]

我需要解决CC2430+SHT11温湿度采集，并能组网发送。通过串口在电脑上显示。有谁有相关程序可与我联系，资源分可以随便给，甚至可以花钱购买。联系邮箱：[e-mail].谢谢！

恩，不错 帮你顶，我来接分的

新手哈!多多指教哟!

我做过SHT10的，楼主你看看读写时序是否和SHT11相同，如果相同那没我的程序可以直接用到你的SHT11上！

楼上的大哥，你的这个程序是用在单片机力，还是用在ARM里的呀？

[lujiajia111]

我也求啊

[DGC_gfc]

我只要采集和发送的子程序？急求 3q

[gfchen1989]

8楼的那个是采集还是发送的程序？求教，QQ:601765796
