Sensor – Transducer – Detector Projects

Final Project Setup

EEG Error Correction Interface

Introduction Our project was an EEG-controlled brain computer interface that allowed a user to correct errors in machine behavior. The project was modeled as a trial-based “game.” In each trial, a solid colored green block or dotted yellow block was placed on a conveyor belt. One end of the conveyor belt had a solid colored …

DHT11 sensor

Measurement of temperature and relative humidity using DHT11 sensor and PIC microcontroller using PIC16F628A

Measurement and control of temperature and relative humidity finds applications in numerous areas. These days devices are available which have both temperature and humidity sensors with signal conditioning, ADC, calibration and communication interface all built inside them. The use of such smart sensors greatly simplify the design and reduces the overall cost. We discussed in …
