This paper presents a low cost Wireless Sensor Network using TCP/IP to use Ethernet configuration and hybrid networks to extend range or improve connectivity in distant areas, in particular is agriculture. The system is designed with soil moisture sensor based on Atmega8L and Nordic nRF24L01 to monitor environmental parameter. Moreover, to make data available globally, we have connected the wireless sensor network to GSM/GPRS. The system not only uses a low power but also has a compact size and applies advantages of TCP/IP
