Dear Miss, Mister.
I'm confused about the axix of sensitivity of your ADXL1001/1002 product.
When moving the accelerometer in the "+" direction, should i have a positive signal at the output of it (pin 30)?
When i' m pointing the accelerometer with the "+" sign to the ground (1g) i'm measuring 2.12 V
At 0g, i have 2.09V
With "+" pointing to the sky, i have 2.06V.
But, when i move the accelerometer in the direction of the "+", i'm measuring a negative pulse on the scope.
Moving in the "-" direction gives a positive one.
I,m very confused with this because we also use ST accelerometers (LIS344 for example) and their indications matches with the accelerometer motion (moving to the "+" gives a positive pulse.
Maybe i'm misinterpretating the datasheet?
Looking forward for your answer.
Best regards.
Hi,
A quick question, when you say negative pulse, is it negative voltage or is it a decreased in voltage but still positive voltage?
Normally corresponding output increases when accelerated along the sensitivity axis.

Hello Mahdi,
Strangely on the ADXL377, when i point the arrow direction to the floor, it gives me a negative output.
To be clear, supplied by 3.3V, the midpoint is at 1.649V (0g), 1.655 at 1g and 1.642 at -1g (arrow to the floor).It's the contrary of the ADXL1001/1002.
I'm still a bit confused with this all.
Best regards.
