About sensor and interface raspberry pi with arduino

  1. 1. Compile by Mayur khatri 1. About Arduino microcontroller  Arduino is open source microcontroller and software development environment and easy to use and understand hardware and software. Arduino is a single board microcontroller has programming language is a simple ‘C’ and ‘C++’ type programming language.  It has facility to GDM, and Bluetooth, motor and other facility. 1.1. Connecting an analog sensor to Arduino It’s a one of the big advantages on the raspberry pi Arduino have in built adc converter this help to interface directly analog sensor (for power [voltage and current] temperature etc. measurement) The analog signal will be converted in levels by the Arduino. The Arduino works with 1024 levels, where level 0 is 0V, level 1023 is 5V. This means that each level is fixed in 4.8 mV (milliVolt). That is the value of the maximum accuracy you will obtain from your system.For example Measurement quantity Sensor name Operating voltage range 1. current Hall effect ACS 712 5v dc +30A to - 30A 2. temperature DS18B20 3.0V to 5.5V -55°C to +125°C 1.1.3 Interface Arduino with Raspberry pi  CONNECT RASPBERRY PI AND ARDUINO WITH SERIAL USB CABLE
  2. 2. Compile by Mayur khatri There are many ways of connecting the Raspberry Pi and Arduino, such as using the GPIO and Serial pins and using I2C. But this could be one of the easiest ways to get them, because hardware that required is minimal: we will need is a micro USB cable that comes with the Arduino.
