inherent locomotion abilities that turns the sensor node dynamics simultaneously
on with an installation of a transceiver. The humanoid is capable of wireless
transmission of sensor data to a place of desired location and accordingly correction
measures can be taken. The system requires the development of three independent
modules namely the humanoid, a transmitter/receiver and a sensor node. The humanoid
is manually operated through an on-board Atmega kit and an interface (computer)
at operators side. It is developed to move forward, turn right and left
and sitting still when power to its servos is turned off. The transmitter/receiver
module operating at 433 MHZ is capable of sending 4 bit parallel data. Transceiver
is fed data through an encoder with 4 data lines, likewise at receiver end a
decoder with 4 output data lines is used. Sensor module consists of Volatile
Organic Compound (VOC) sensor, studied with ethanol in the present paper. Its
output is fed to 4 comparators whose outputs in turn are fed to data lines of
an encoder which is provided with 4 variable range concentration windows. Finally
sensor and transmitter/receiver module is integrated and installed on the humanoid.
Hence humanoid can be sent to a remote location and ethanol concentration can
be detected.]]>Sample and Kit Total Solution,20072007Holtek Semiconductor Inc.,20002000Fujun, H., S. Yingfei, L. Xiaolei and D. Zhijiang,20092009pp: 237242Tanie, T. and K.
