HTS221 T0_OUT & T1_OUT = 0

[MTrav.19]

Currently having some issues reading the temperature correctly from the HTS221 sensor.

The Coefficients read as follows.

H0_T0_OUT = 0x5246

H0_rH_x2 = 0x57

H1_T0_OUT = 0x0000

H1_rH_x2 = 0x95

T0_OUT = 0x0000

T0_degC_x8 = 0x27

T1/T0 MSB = 0x4B

T1_OUT = 0x0000

T1_degC_x8 = 0x20

Outputs:

H_OUT = 0x1469

T_OUT = 0x09ED

The humidity seems to be working fine but the temperature does not appear to be correct. Any help would be much appreciated.

Thanks,

Matt

Hi Matt, I'm wondering if you are correctly reading the values. Did you calculate the rH through the formula (p.2 TN1218)? I'm getting rH 20% with your values...

Are you correctly reading the WHO_AM_I (0Fh) register? Btw, if the T0_OUT and T1_OUT values are effectively 0h, the sensors are probably wrong calibrated... can you check the same registers on other HTS221? Regards
