چکیده انگلیسی
We have created a pilot wireless network for the convenient monitoring of temperature and humidity of infant incubators. This system combines infrared and radio frequency (RF) communication in order to minimize the power consumption of slave devices, and we therefore call it a hybrid wireless network. The slave module installed in the infant incubator receives the calling signal from the host with an infrared receiver, and sends temperature and humidity data to the host with an RF transmitter. The power consumption of the host system is not critical, and hence it uses the maximum power of infrared transmission and continuously operating RF receiver. In our test implementation, we included four slave devices. The PC calls each slave device every second and then waits for 6Â s, resulting in a total scan period of 10Â s. Slave devices receive the calling signals and transmit three data values (temperature, moisture, and skin temperature); their power demand is 1Â mW, and can run for about 1000Â h on four AA-size nickel-hydride batteries.
