Introduction The Dexter Industries Inertial Motion Unit (IMU) Sensor measures acceleration, tilt, and rotation on all three axes.  The sensor combines an accelerometer and a gyroscope into one sensor for the LEGO Mindstorms system.  Build robots that know which way is up, can measure tilt, balance themselves, and measure acceleration and rotation on all axes all at once. Accelerometer:...

Introduction The Dexter Industries Thermal Infrared Sensor reads surface temperatures of objects.  It is a non-contact thermometer based on the MLX90614.  Detecting the infrared radiation from an object, the sensor can read object temperatures between -90°F and 700°F (-70°C and +380°C).  The sensor has a high accuracy of 0.5°C and a resolution of 0.02°C. The Thermal Infrared Sensor reads...

Introduction The Dexter Industries Wifi sensor for Lego Mindstorms NXT is a sensor designed to allow your NXT to connect to the internet via a local Wifi network.  The sensor operates with standard 802.11 b/g/n access and can be configured to run on the vast majority of home networks. The Dexter Industries Wifi Sensor connects to the NXT via...

GPS – The Dexter Industries GPS is a GPS unit manufactured for use with the LEGO® MINDSTORMS® NXT. The sensor calculates positional and navigational data. It then delivers latitude, longitude, time, velocity, angle of travel, and navigational information such as distance and angle to a specified destination.   Getting Started Hardware: Connect the GPS unit to the NXT using...

Thermal Sensor User Guide  V 1.0 What is the Thermal Sensor? The DI-Thermal Series by Dexter Industries is a line of temperature sensors compatible with the Lego NXT Mindstorms system.  The sensors offer an operating range of -50°C to 150°C. The thermal sensors provide an analog signal, which is read by the NXT hardware.  The sensor can be used...

dFlex – The dFlex is an analogue sensor that measures bending.  dFlex flexible sensor measure angular displacement, or bend, of the sensor.  The sensor bends and flexes with mechanical motion, sending a varying analogue signal back to the NXT. The dFlex can be mounted using Technic bricks, mechanical methods, Velcro, or 3M medical tape. Hardware: The basic dFlex kit...
