I'm going to measure the earth magnetic field (B < 0.5G) in Z direction using hall sensor,

I've found DRV5053 quite interesting however, I've not found any information regarding its resolution (uG, nT),

would you please tell me if I am in a right way or not?

Hello Mahdi,

Have you looked at our DRV425 which is a flux gate device. It has a smaller range and is more accurate. I think for measuring lower fields this will work for you.

Dear Javier,

Thank you so much for new suggestion, I read the datasheet there are many useful information, however I can not find the resolution of sensor itself,

- Offset: ±8 µT (Max)
- Offset Drift: ±5 nT/°C (Typ)
- Gain Error: 0.04% (Typ)
- Gain Drift: ±7 ppm/°C (Typ)
- Linearity: ±0.1%
- Noise: 1.5 nT/√Hz (Typ)
Sensor Range: ±2 mT (Max)

for example , what is the minimum magnetic Variation value that can be measured by these sensors? (resolution?)

Is there any results from factory measurement or test regarding resolution

Thank you so much for your time and consideration,

regards,
