Tobin creg, thanks for your desire to help me out. I intend to use the following sensors: Humidity, Light, Environmental temperature sensor, and Soil moisture sensor. There is something you have mentioned which is interesting; that it is not easy to write the codes for zigbee, so what other alternative are there. My plan was to use the following hardware:
Humidity sensor.
Temperature sensor.
Light sensor.
Soil moisture sensor.
Arduino uno (microcontroller board)
Relay control module that will drive a variety of actuators.
Xbee series 2 module
Xbee explorer (usb)- for modification of firmware.
Like i said in my earlier post, i have read so much on this research topic, but i have come to realise that reading without hands on practical make the whole thing boring. I live in Nigeria, and so far i have not been able to find a store were i can get these hardware. pls u can give suggestion/ advice in this regard.
Good bless you.
