Thank you for purchasing the Smart Wireless Force Accelerometer. We pride ourselves on producing high quality products that meet with the demands of the busy classroom environment. If you have any problems using this sensor, please read this documentation in full before contacting the Data Harvest support team. 


Overview

The Wireless Force sensor has a:


  • Force sensor that can measure forces in the range -100 to + 100 N
  • An acceleration sensor that can measure accelerations in the range 0 to 150 m/s2 along three axis (at one time)
  • A Gyroscope sensor that can measure rotation about three axis (one at a time) in the range 0 to 8m/s


The force sensor is an aluminium load cell with a 3mm threaded connection point. The gyro and acceleration are silicon mems sensors mounted on the circuit board.


A pair of holes at the top of the sensor allows the user to hold the sensor using their fingers, between the finger holes is a smaller ovoid hole with a screw to fix the sensor firmly to a metal rod, the ovoid shape of the hole ensures the connecting rod is centralised with respect to the hole.


The sensor is a versatile piece of apparatus that will allow an investigator, for example, to study force changes in a pendulum swing. Force – extension for Hooke’s law, impulse, and static and kinetic friction. The accelerometer can be used to show g, free fall and F = ma.


The sensors can record at high speed (50 us between samples) if it is the only sensor connected. Number of ranges in use from the same sensor will not affect this. However, if you connect additional sensors the inter-sample time will increase
