Split output of one temperature sensor to two independent signals using an op amp buffer
That is a NTC thermistor, the output is variation in resistance not voltage or current so you cant practically use a buffer circuit to do this. this would require some sort of circuit rather than just buffer. feeding two devices from one NTC is also not a good option since the input to these devices have voltage divider resistor and resistance may vary from device to device.The best way to do this without complications is to use two NTC of same type,value,manufacturer place them together and connect them individually to each device.
