Interfacing DS18B20 Temperature sensor with Raspberry Pi

Vivek Kartha — Mon, 09 Mar 2015 10:10:14 +0000

DS18B20 is a commonly used temperature temperature sensor providing 9 bit to 12 bit digital Celsius temperature measurements. The sensor communicates over one wire bus. Each sensor has a 64 bit serial code enabling multiple sensors to be connected to the same one wire bus. The Raspberry Pi has drivers for one wired devices to […]

RFID (Radio Frequency Identification) uses electromagnetic fields to read, monitor and transfer data from tags attached to different objects. It is not necessary that the cards are to be in visibility of the reader, it can be embedded in the tracked object. The tags can be actively powered from a power source or can be […]

Using UART on Raspberry Pi – Python

Vivek Kartha — Fri, 20 Feb 2015 17:19:50 +0000

UART stands for Universal Asynchronous Transmitter / Receiver, a popular serial communication interface which provides full duplex communication between two devices. The term universal means that transmission speed and data format are configurable. As it is asynchronous it doesn’t need to send clock signal along with the data signals. UART uses two data lines for […]

Interfacing HC-SR501 PIR Motion Sensor with Raspberry Pi

Vivek Kartha — Wed, 04 Feb 2015 09:31:17 +0000

All living beings radiate energy to the surroundings in the form of infrared radiations which are invisible to human eyes. A PIR (Passive infrared) sensor can be used to detect these passive radiations. When an object (human or animal) emitting infrared radiations passes through the field of view of the sensor, it detects the change in […]

Interfacing HC-SR04 Ultrasonic Sensor with Raspberry Pi

Vivek Kartha — Fri, 30 Jan 2015 11:26:06 +0000

Ultrasonic distance sensors are designed to measure distance between the source and target using ultrasonic waves. We use ultrasonic waves because they are relatively accurate across short distances and don’t cause disturbances as they are inaudible to human ear. HC-SR04 is a commonly used module for non contact distance measurement for distances from 2cm to […]
