有这样的吗?可不可以提供资料?
这是我做的电路!
希望大家提供宝贵意见!
RB1与RB2的阻值是否正确?
R3与R4的阻值怎么确定?

@davidhjk
可以聊聊啊,我有个成熟的方案.QQ:631510115.
zhouchuanggpoi:
以10K的NTC Thermistor为例,在50度的RTH值为4.16K,在负5度的RTC值为33.9K.根据公式则有
RT1＝7.903K＝7.87K
RT2＝18.229K＝18.2K
后面的等号是标准电阻
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.
