Build Your Own Arduino Weather Station

Image
Build Your Own Arduino Weather Station In this project, we will be making a weather station that measures air pressure, temperature, rain drop, soil humidity and air humidity using Arduino which save the data for data acquisition! or this project, we will be using: - Arduino boards (mine Arduino Uno Rev3) - DHT11 Humidity and temperature sensor  - BMP185 Barometer sensor  - Rain Drop sensor module  - Soil Humidity sensor module  - Breadboard or Custom ProtoShield - Jumper Wire In general, the connections are very simple. Follow the instructions and images above, and you should have no problems. Connecting Rain Drop Module the VCC pin on Arduino’s 5V output the GND pin to Arduino’s GND and the Analog Data to Arduino's analog pin 0 Connecting Soil Humidity Module the VCC pin on Arduino’s 5V output the GND pin to Arduino’s GND and the Analog Data to Arduino's analog pin 1 Connecting BMP185 the VCC pin on Arduino’s 3.3V output t

Using the L239D motor driver IC details

Image
================================================================== Using the L239D motor driver IC From Microcontroller we can not connect a motor directly because microcontroller can not give  sufficient current to drive the DC motors. Motor driver is a current enhancing device,it can also be act as Switching Device.  Thus we insert motor driver in between motor and Microcontroller.  Motor driver take the input signals from Microcontroller and generate corresponding output for motor. Motor Driver IC L293D : This is a motor driver IC that can drive two motor simultaneously.  L293D IC is a dual H-bridge motor driver IC. One H-bridge is capable to drive a dc motor in  bidirectional. L293D IC is a current enhancing IC as the output from the sensor is not able to  drive motors itself so L293D is used for this purpose. L293D is a 16 pin IC having two enables  pins which should always be remain high to enable both the H-bridges.  L293B is another IC o
