source code for interfacing humidity sensor with lpc2148

ABSTRACT

In this paper, we describe about the monitoring of Indian agriculture using LPC2148.Monitoring of Indian agriculture is
done using information of the temperature and humidity content. This is mainly used for saving water and monitoring agriculture without human presence. Temperature sensor and humidity sensor will continuously sense the information regarding the field. When the values are less than or greater than the threshold values it will do certain operations. We are usin ....etc
