That is, maybe your device needs accuracy in both XY and xy directionsIt's different. This frequency is related to precision. You can think of it as two separate acceleration sensors, the ADXL210E contains sensors in both directions XY. To put it simply, T2 is the duration of the pulse width in the next clock with a certain duty cycle, so the time of 1/f must be longer than T2, in other words, T21/f, is such a relationship.
1, can be understood as using the traditional accelerationDegree chip semiconductor process and material acceleration chip , using micron technology to manufacture micro machinery acceleration chip , and integrate it with the corresponding circuit as a whole technology. There are many kinds of MEMS sensors acceleration chip , G-sensor is a kind of MEMS sensor. G-sensor (Gravity sensor), also known as acceleration sensor (accelerometer is a MEMS sensor that senses acceleration.
2, G-sensor is a gravity sensor, used to detect the direction and acceleration of the device. It can detect the motion state of the equipment, tilt direction and gravity acceleration and other information. G-sensors are commonly found in devices such as smartphones, tablets and game controllers. Using G-sensor, the device can automatically rotate the screen, shake operation, posture recognition and other functions according to gravity sensing.
3, G-sensor, that is, acceleration sensor, is drivingEnvironmental factors, etc., to determine its maximum allowable acceleration range.
chip is even worse, it is easy to burn the chip. If the cold pressure connection or tightly inserted into the socket hole, at low frequencies (tens of KHz) if it can resist 10g (gravitational acceleration impact), it can be used.
