Bluno Nano – An Arduino Nano with Bluetooth 4.0
The Bluno Nano is perfect for BLE projects with limited space or weight. Everything is getting smart now: wristbands and watches monitor your daily behaviour and become social; phone-controlled camera add-ons move and take shots as you like; smart gardens grow virtually in your iPad and sharing is made easy. The Bluetooth Low Energy technology has made it easy and achievable. DFRobot's Bluno family is first of its kind in integrating BT 4.0(BLE) module into Arduino Uno, making it an ideal prototyping platform for developers to go wireless. You will be able to develop your own smart bracelet, smart pedometer and more. Through the low- power Bluetooth 4.0 technology, real-time low energy communication can be made easy.
BME680 (Temperature, Humidity, Pressure and Gas Sensor)
This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price! Like the BME280 & BMP280, this precision sensor from Bosch can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy! The BME680 takes those sensors to the next step in that it contains a small MOX sensor. The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can be used to detect gasses & alcohols such as Ethanol, Alcohol and Carbon Monoxide, and perform air quality measurements.Note: it will give you one resistance value, with overall VOC content, but it cannot differentiate gasses or alcohols.
BMP085 (Barometric Pressure Sensor Module for Arduino)
BMP180 (Digital Barometric Sensor Module)
BMP280 (I2C/SPI Digital Barometric Pressure Sensor Module for Arduino)
The BMP280 sensor is an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI.
Features:
- Pressure range: 300 ~ 1100hPa (altitude 9000 m ~ -500 m); - Working voltage: 1.71 - 3.6VDC; - Low power consumption: 4μA; - High precision: at low-power mode, the resolution is 0.06hPa (0.5 meters); - Temperature output; - Communication interface: I2C or SPI; typical application: - GPS precise navigation (dead reckoning, the upper and lower bridge detection, etc.); - indoor and outdoor navigation; - The weather forecast; - The vertical velocity indication (rise / sink speed); Note: You need to add 5V to 3.3V level converter circuit between Arduino UNO R3 and the module.
