Wireless Sensing Network for My Next Project

In this project, we will be creating an incredible Wireless Sensing Network. This project uses the TH71221 RF, which we will use in the RF transceivers. The source of this project also discusses how the TH71221 RF is being used with other external components in building the WSN node like that of the microcontroller and sensors.

So what’s a Wireless Sensing Network? It is a network consisting of spatially distributed autonomous modules (called nodes) using sensors to monitor physical or environmental conditions such as temperature, pressure and humidity. It’s a good compliment to the previous project we have about InfraRed thermometer. The devices we will be using will communicate wirelessly to a main sensor node which collects back all the measurements and sent it to a main station, like a computer, for further processing.

This is where the device can be applicable:

• Wireless sensing networks for temperature, humidity, light and RF field strength
• Home and building automation

Even around with several components, the TH71221 RF transceiver used in this project can be used in a low cost wireless sensing network applications. While Melex TH71221 is used to transmit as well as receive information over a wide frequency range of 300 to 390 MHz, the external microcontroller handles the network protocol of this communication.
