Smart monitoring information system based on RF 433 Mhz (SMIS) (Hicham Ouldzira)

5145

The smart control system is effective due to the following advantages:

 It maintains a dynamic balance through self-configuration and self-organization.

 It is easy to set up and maintain.

 The control modules have been designed in standard sizes.

The controller and these modules constitute a WSAN.

A WIRELESS SENSOR AND ACTUATOR NETWORK

Wireless communications namely Zigbee, Wi-Fi, Bluetooth and 433 MHz, have been widely used in

many applications recently. the following Table 1 gives a comparison between these wireless technologies in

terms of band operated, energy consumption, range, debit and battery life [19]:

433 MHz wireless communication is available worldwide and an open source alternative. It is ideal

for wireless sensor network applications because it can transmit / receive over very long distances without

requiring high power consumption on a battery. The low input current of typical label configurations can

power button cell batteries or thin-film batteries up to 10 years.
