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

Antennas
A good antenna works
A bad antenna is a waste of time & money
Antenna systems can be very inexpensive and simple
They can also be very, very expensive

Antenna Considerations
The space available for an antenna
The proximity to neighbours
The operating frequencies you will use
The output power
Money

Antenna Types
High Frequency
1.6 - 30 Mhz + 50 Mhz
160 - 6 metres
An antenna s size/length depends on the frequency
It s functionality largely depends on the height above gro ....etc

basic antenna theory ppt

Antenna theory and antenna terminology can seem complicated to the uninitiated. A lot goes into designing antennas but with a little bit of guidance and explanation, antenna users (network designers, systems integrators, end users) can read through the antenna specifications and choose the right antenna style for their wireless network design.

In this paper we will go over some simple techniques to help you better understand some terminologyused and how it is applied in the Antenna industry. This will be part one of a ....etc

interfacing of humidity sensor with 8051 microcontroller pdf

Abstract

This project is about a simple humidity sensor based on 8051 microcontroller. Humidity sensor is also called hygrometer. This circuit can sense relative humidity (RH) from 20% to 95% at an accuracy of 5%. The humidity information is displayed on a 16 2 LCD display. A relay is also provided which is set to be active when the humidity crosses a certain trip point. The circuit is mains operated and it is very easy to install. DHT11 is the humidity sensor used here.DHT11 is a ....etc
