Specific protocol (SENSLOG) over TCP/IP for sensors applications

2005

The objective is to obtain an embedded system using a microcontroller that will communicate with other devices over a specific protocol (SENSLOG) over TCP/IP for sensors applications. The protocol has been designed for this application, but the commands are generic. They can be used for any type of sensing. We must take into account that this program will run in a microcontroller and it will communicate with another program running in a PC. The protocol is based on commands, like SMTP. From the PC we will send commands to the microcontroller to do specific tasks, and if it is necessary, the microcontroller will answer to the PC. Some of the functions designed for this protocol are: to contr…

Vibration Detector Based on GMR Sensors

2009

Up to now, vibrations have mostly been sensed by measuring displacement, velocity, and acceleration. The most common types of vibration sensors are piezoelectric, capacitive, null-balance, strain gage, optoelectronic, resonance beam, and piezoresistive. We present a low-cost and low-power vibration detector based on the measurement of magnetic field variations induced in a recent SS501 giant magnetoresistance (GMR) magnetic sensor, for which has never been applied. Vibrations on small ferromagnetic pieces disturb the Earth's magnetic field. These weak perturbations can be detected and measured over the assumed constant Earth's magnetic field, which is uniform over a wide area. A novel array…
