IMU seneor (accelerometer)

semiconductor_user — Tue, 03 Feb 2026 23:41:50 GMT

hello,

i have few basic Question regarding accelerometer sensor.

1. accelerometer data coming from imu sensor that is 2's compliment data, so should i receive this data in signed integer or unsigned integer?

2. i want to know whatever raw data is coming from this sensor resgistors of accelerometer that is mg/LSB or only g ? if it is mg/LSB then how i can covert into g (refer ±2g)?

3. formula of convert g into (-180° to 0 to 180°) ?

please refer below i attached Mechanical characteristics document.

NOTE: consider everything for XYZ axis, and for 1 axis 2 register provoid (e.g Xaxis_H_A ,Xaxis_L_A)

Hello Hiren,

Looking at the screenshots, it appears you are using the ASM330LHH from STMicroelectronics. Therefore I would recommend posting these questions on the ST Community.

yeah i know but generally i'm asking this Questions,forget for some time about asm330lhh sensor just think i am working with imu sensor and i want to know about above asked Questions finally i'm intract with nxp microcontroller that's why i'm asking here.

Hello Hiren,

Please refer to our Sensor Algorithms and Component Libraries to understand how to convert raw accelerometer data to real values in g’s and inclination in degrees.
