SEN0178 Datasheet
3-Axis acceleration sensor is an electronic equipment which could measure the acceleration during the object motion. It could help you to analyse the target motion position or direction. The typical interactive application could be the posture recognition and action recognition, such as WII game applications. These video game device are all using internal acceleration sensor, calculate the current motion direction by conversion algorithm. And most of the recent smart device are based the same theory, like Misfit, Microsoft band .etc. FXLN83XXQR1 family is a low power consumption with high precision sensor. The highest bandwidth could arrive 2.7kHz. And analog output could be compatible with most MCU.

| Triple Axis Accelerometer FXLN83XX Series Introduction 3-Axis acceleration sensor is an electronic equipment which could measure the acceleration during the object motion. It could help you to analyse the target motion position or direction. The typical interactive application could be the posture recognition and action recognition, such as WII game applications. These video game device are all using internal acceleration sensor, calculate the current motion direction by conversion algorithm. And most of the recent smart device are based the same theory, like Misfit, Microsoft band .etc. FXLN83XXQR1 family is a low power consumption with high precision sensor. The highest bandwidth could arrive 2.7kHz. And analog output could be compatible with most MCU. Specification • Power Supply 3.3-8V • Optional Sensitivity ±2g/8g FXLN8361QR1 & FXLN8371QR1 ±4g/16g FXLN8362QR1 & FXLN8372QR1 • Low power consumption 180 uA working current • High sensitivity • Low-pass filter with internal signal processing functions • Stable performance, shock-proof capability. • Dimensions 37.44X26.43mm User Manual FXLN83XXQR1_Front FXLN83XXQR1_Back Chip Bandwidth SEN0178 FXLN8361 ±2g ±8g SEN0179 FXLN8362 ±4g ±16g SEN0180 FXLN8371 ±2g ±8g High SEN0181 FXLN8372 ±4g ±16g High Note "H" = High resolution, Low range "L" = Low resolution, High range There is a sensor table on the back of the PCB, it will show your sensor chip type, measurement range and bandwidth. You could select the measurement range via the range switch. E.g. If your sensor chip type is “FXLN8361QR1” When the switch is "H", th e measure range will be "±2g" when the switch is "L", the range will be "±8g Tutorial In this section, we will teach you how to read the correct accelerated velocity. Sample SEN0178 Preparation • Hardware DFRduino UNO R3 x1 I/O Expansion shield V7 x1 SEN0178 x1 • Software Arduino IDE click here to download Arduino IDE Connection Diagram Data Calibration Due to sensor individual difference, we need make a calibration for each module. Or you could skip this step, and test the sensor directly. • Step 1 Turn the switch to "H" position, and connect the sensor according to the connection diagram. Upload the testing code to Arduino. /* DFRobot 3-axis calibration code void setup Serial.begin 9600 void loop int x,y,z x=analogRead 0 y=analogRead 1 z=analogRead 2 Serial.print "x= " Serial.print x*5/1024.0,3 Serial.print ',' Serial.print "y= " Serial.print y*5/1024.0,3 ; Serial.print ',' Serial.print "z= " Serial.println z*5/1024.0,3 delay 500 ; |
