Instructions for QM50TF-HB

1. Power Supply:

   • Ensure the supply voltage is within the range of 2.7V to 5.5V.
   • Connect the Vcc pin to the positive supply and GND pin to the ground.

2. Operating Current:

   • The typical operating current is 3.0 mA. Ensure your power supply can provide this current.

3. Peak Current:

   • The peak current should not exceed 10 mA to avoid damaging the device.

4. Frequency Range:

   • The device operates at a fixed frequency of 50 kHz. Ensure any external circuits or signals are compatible with this frequency.

5. Sensitivity:

   • The sensitivity is 200 mV/G. This means the output voltage will change by 200 mV for every 1 G of acceleration.

6. Bandwidth:

   • The bandwidth is 500 Hz. This is the range of frequencies over which the device can accurately measure acceleration.

7. Temperature Range:

   • The device is designed to operate within a temperature range of -40°C to 85°C. Ensure it is used within these limits to maintain performance and reliability.

8. Storage Temperature:

   • When not in use, store the device within a temperature range of -40°C to 125°C to prevent damage.

9. Handling:

   • Handle the device with care to avoid mechanical shock or static discharge.
   • Use appropriate ESD protection when handling the device.

10. Mounting:

    • Mount the device on a stable surface to ensure accurate readings.
    • Avoid mounting in areas with high vibration or mechanical stress.

11. Testing:

    • Before deploying the device, perform initial testing to verify its functionality and accuracy.
    • Regularly calibrate the device to maintain measurement accuracy.
