Description: This project describes how to build a simple wireless RF Temperature transmitter which uses TXM-433 module ,AVR micro controller and the PC side consists of SILRX-433 (Receiver) connected to PC via RS232 port. RF Temperature transmitter sends six bytes of data at fixed interval. Module measures three temperature values, light level at photocell and [...]
Description: This project is a CAN based home automation system. The system does different tasks such as switching ON/OFF the applianc, decode commands from Ir remote control units, control thermostats, measure temperature and more. All this units communicates with each other through CANBus and the status can be monitered through PC. Micro controller: AT90S4433 For [...]
