#RASPBERRY PI PROTEUS LIBRARY HOW TO#

We will use Adafruit to easily operate this LCD in 4-bit mode, so we will install it in our Raspberry Pi. Sensor data will be displayed on a 16 x 2 LCD display. Installing the Adafruit LCD library on your Raspberry Pi: You should also have access to your pi either through terminal windows or through other application through which you can write and execute python programs and use the terminal window Your Raspberry Pi should be interfaced with an Operating System and should connect to the internet. With the increase in temperature, the value of resistance will decrease. The second component is a surface mounted NTC (Negative Temperature Coefficient) Thermistor. Keep in mind this relative humidity not actual humidity so it measured the water content in the air relative to temperature in the air. the measured resistance is inversely proportional to the relative humidity of the environment. One is a pair of electrodes the electric resistance between these two electrodes is controlled by the moisture holding substrate i.e. The sensor comes with a blue or white casing which has two important components we will use. Both of them differ in this sense that the sensor has a filtering capacitor and a pull-up resistor attached to the output pin of the sensor.

We will be using the module form in this tutorial. It is available in a module form and a sensor form. It also measures humidity from 20-90% RH with an accuracy of В±5 %. It measures temperature from 0-50вЊ with an accuracy of в’ вЊ. The DHT11 is a basic, low cost, digital humidity, and temperature sensor.

In this article, we will be teaching you how to interface a DH11 sensor with your Raspberry Pi which will display its readings on a 16Г—2 LCD screen. We can easily interface the DHT11 with our microprocessors/microcontrollers. One common sensor is the DHT11 which not only offers accuracy but a wide range too. Measuring temperature and humidity are useful functions performed by various sensors.
