Hi
I thinking to use tmp006 for my project.
The problem is sensor can’t detect the low temperature as well as TMP006 EVM have same. I put one object in to the freeze at -10 degree C until 10 minutes and after I was measured temperature by TMP006 EVM and TMP006 Breakout board and both sensor was shown object temperature >10 degree C. But both sensor can detect hot temperature.
In TMP006 datasheet its said that sensor can detect temperature from ±1.5°C (max) from –40°C to +125°C.
What is mean by ±1.5°C?
This value i used during the program.
#define TMP006_B0 -0.0000294
#define TMP006_B1 -0.00000057
#define TMP006_B2 0.00000000463
#define TMP006_C2 13.4
#define TMP006_TREF 298.15
#define TMP006_A2 -0.00001678
#define TMP006_A1 0.00175
#define TMP006_S0 6.4 // * 10^-14
Thank you for help and support.
Sincerely,
