Ultrasonic Sensor HC-SR04

The HC-SR04 ultrasonic sensor uses sonar to determine distance to objects like bats or dolphins do. This module offers excellent range accuracy and stable readings in an easy-to-use package. Its operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect). Ranging accuracy can reach to 3mm.

Pressure Sensor BMP180

BMP180 is a high precision, small volume, low energy consumption pressure sensor, which is commonly used in mobile devices. It can achieve accurary of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw for battery powered applications. The BMP180 comes fully calibrated and ready to use. Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation.

OLED Display 128x64

OLED (Organic Light-Emitting Diode) display is 0.96" and has a resolution of 128 * 64 pixels. It uses a standard (configurable) serial interface for communication.By default the module is configured to use an SPI interface for serial interface but can be modified (soldering required) to communicate via I2C protocol. OLED is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays.
