Tips: Selection Guide of Triaxial Accelerometer Sensor.

1. Output type

This is the first thing to consider. This depends on the interface between your system and the accelerometer. Generally, the voltage and acceleration of the analog output are proportional, for example, 2.5V corresponds to an acceleration of 0g, and 2.6V corresponds to an acceleration of 0.5g. Digital output generally uses pulse width modulation (PWM) signals.

If you use a microcontroller with only digital inputs, such as BASIC Stamp, then you can only choose a digital output accelerometer, but the problem is that you have to take up an extra clock unit to process the PWM signal, and it is also for the processor. A big burden.

If the microcontroller you are using has an analog input port, such as PIC/AVR/OOPIC, you can easily use an acceleration sensor with an analog interface, all you need is to add a command similar to "acceleration=read_adc()" in the program , And the speed of processing this instruction is only a few microseconds.

2. Number of measuring axes

For most projects, the two-axis acceleration sensor can already meet most applications. For some special applications, such as UAV and ROV control, a three-axis acceleration sensor may be suitable.

3. Maximum measured value

If you only need to measure the inclination angle of the robot relative to the ground, a ±1.5g acceleration sensor is sufficient. But if you need to measure the dynamic performance of the robot, ±2g should also be sufficient. If your robot will suddenly start or stop, then you need a ±5g sensor.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
