HiTechnic NXT Force Sensor for LEGO Mindstorms NXT
The HiTechnic Force Sensor measures the force applied to the cross axle receptacle and converts it into a signal that can be used by the LEGO Mindstorms NXT. The force can be read using LEGO Mindstorms NXT Software Force Sensor Block. When using other programming languages, the Force Sensor can be read as though it is a LEGO Light Sensor.
The sensor measures the force applied by a LEGO axle being pressed into the sensor as shown by the arrow below.
The chart shows the sensor value relative to the force applied, in grams, to the sensor.
The Force Sensor can be programmed using LEGO Mindstorms NXT-G Software by importing the Force Sensor Block. This and other HiTechnic sensor programming blocks are available from the downloads page.
The Force Sensor Block provides access to the sensor output in addition to other features.
- The number shows which of your NXT's ports are connected to the Force Sensor. You can change this number in the configuration panel if you need to.
- The block's data hub will open automatically when the block is placed in the work area. At least one data wire must be dragged from the block's output plug to another block's data hub.
Configuring the Force Sensor Block
The sensor may be connected directly to an NXT sensor port or via the HiTechnic Sensor Multiplexer (MUX). When configuring the sensor via the multiplexer, there are two port selections to make. The first is the NXT to MUX connection and the second, the MUX to SENSOR connection.
Other Programming Environments
The Force Sensor is an analog sensor like the LEGO Light Sensor. Therefore the same way you read the LEGO Light Sensor can be used to read the Force Sensor value.
