本人是這方面的生手,希各位能幫咱提提建議!
在此謝謝各位了!

有這樣的嗎?可不可以提供資料?
這是我做的電路!
希望大家提供寶貴意見!
RB1與RB2的阻值是否正確?
R3與R4的阻值怎么確定?

databook 里有詳細(xì)的介紹,要先知道你的熱敏電阻在你想設(shè)定的最高與最低溫度時(shí)的阻值就可以計(jì)算了.

可以聊聊啊,我有個(gè)成熟的方案.QQ:631510115.
zhouchuanggpoi:
以10K的NTC Thermistor為例,在50度的RTH值為4.16K,在負(fù)5度的RTC值為33.9K.根據(jù)公式則有
RT1＝7.903K＝7.87K
RT2＝18.229K＝18.2K
后面的等號(hào)是標(biāo)準(zhǔn)電阻
Where R(TC) is the cold temperature resistance and R(TH) is the hot temperature resistance of thermistor, as
specified by the thermistor manufacturer.
RT1 or RT2 can be omitted If only one temperature (hot or cold) setting is required. Applying a voltage between
the V(TS1) and V(TS2) thresholds to pin TS disables the temperature-sensing feature.

或者用這個(gè)軟件,可以算BQ系列的.很好的東東.
