Other Parts Discussed in Thread: DXP
Hi,
I'm working with TMP432 and I used the PNP 2N2907A as remote sensor with GND collector-connected. I need to sense and regolate temperature up to 175°C.
I'm looking a very high spread beetween temperature measured by TMP432 and by a thermometer, up to 10°C.
For example with a temperature of 100°C the TMP432 read 110-112°C.
If I increase the ambient temperature at the same value of remote ambient, the internal sensor of TMP432 measure the correct temperature.
The Bfactor used is the dafault (0x25h = 08hex) and I'm working with two remote sensor that measure the same error.
Can you suggest any other programming to improve the measure.
No capacitor or series resistor is mounted on remote sensot PNP.
Thanks.
Corrado
