Connecting Multiple Sensors to Arduino Uno

I am a newbie to arduino. I am planning a project based to Home Security and Monitoring using Arduino. For this i will need to connect multiple sensors like humidity,temperature etc to the chip. Please tell me how to do that.

Hi,

Suggestions: See THIS PAGE for how-to on many Arduino items.

Also see sensors here:

Use the photon-pixel coupling method on Arduino UNO. You will need a video camera with an Arduino for that, and a couple of LEDs.

With this method and an Arduino UNO you can read thousands of sensors in parallel, yes, thousands !

Look for suitable sensors , such BME 280, Ds18b20. Each has an available library of examples .

Look at the following diagram and appreciate the power of UNO, NANO, and Arduino IDE to manage so many sensors and peripheral devices for data acquisition, processing and presentation.

1. Sensors
(1) LM35 : Analog type temperature sensor
(2) DS18B20 : Digital type temperature sensor
(3) BME280 : Temperature, Humidity, and Pressure sensor

2. Peripheral Devices
(1) 16x2 Character type LCD
(2) DS3231 Real Time Clock Chip/Module
(3) Potentiometer -- R1
(4) Command Buttons -- K1 and K2

3. Inter Communication Channels
(1) UART Port based communication
(2) I2C Bus based communication
(3) SPI Port based communication

hi… i want to digital read of 5 LM393 Speed sensor and return its values in 20*4 LCD… pls help me to develop the code…
for single sensor its is working… but multiple sensor i am facing trouble…
