文件:Microduino-Station-rect.jpg Microduino-Cube-Station Microduino Stations module integrates three types of sensors, which are light intensity sensor (TSL2561), digital pressure sensor (BMP180), digital temperature and humidity sensor (AM2321). Using the I2C interface connects to the core module. Widely used in weather monitoring. Features Integrates three sensors and using IIC interface, save IO port; Small, cheap, stackable, opened platfrom; Open source hardware circuit design, compatible with the Arduino IDE development environment for programming; Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly. 2.54 pitch row female connector for easy integration into breadboard. Specifications Light intensity sensor：TSL2561 Programmable interrupt, the user can define the upper and lower limitation； 6 digital outputs, working in fast mode at 400kHz； Programmable analog gain and integration time; Automatically rejected 50/60-Hz lighting； Low active power (0.75 mW typical) and power-down mode； Meet RoHS。 Digital pressure sensor：BMP180 BMP180 comprise resistive pressure sensor, AD converter, and a control unit; The control unit includes E2PROM and I2C interfaces. BMP180 transfers the temperature and pressure values without compensation. EEPROM 176 stores the separate standard data, the standard data used to compensate temperature dependence and the other sensor parameters. Available range：300hPa to 1100hPa (corresponding sea level -500m to +9000m)； Lowest absolute accuracy can be achieved to 0.03hPa； UP=pressure(16 to 19bit) UT=temperature data (0 to 15bit); Digital temperature and humidity sensor：AM2321 Standard IIC interface; Digital signal output, precise calibration, low power consumption; Electrical Characteristics Power supply is 2.6-5.5V, standard value is 5V; Sleep mode, current consumption 8uA, measurement mode 500mA; Sampling period can reach to 2s. Temperature Performance Resolution：0.1℃； Scale range：-40-80℃； Accuracy：±0.3℃； Response time：less than 5S. Humidity Performance Resolution：0.1%RH； Scale range：0-99.9%RH； Accuracy：25℃下±3%RH； Response time：less than 5S. Extended Pin Onboard reset button; MicroUSB power supply; Onboard 3.3V regular, power (5V, 3.3V) indicator; VDD selects the 5V or 3.3V power via jumper. Default no connection, need to welding by yourself; Onboard Microduino OLED interface; Two digital button and connected to D4, D5； IIC interface; External expansion Sensor Interface: VDD, A1, GND, VDD or VDD, A1, GND, GND or VDD, D6, GND, VDD or VDD, D6, GND, GND. You can connect them by yourself. 文件:Microduino-Cube-Stations-Pinout1.jpg Microduino-Cube-Stations-Pinout 文件:Microduino-Cube-Stations-Pinout2.jpg Microduino-Cube-Stations-Pinout Document Eagle PCB local download Main components： Light intensity sensor TSL2561： 文件:TSL2561.pdf Digital pressure sensor BMP180： 文件:BMP180 en.pdf Digital temperature and humidity sensor AM2321： 文件:AM2321.pdf Development You may need following linbrary: Application You can download the Microduino test program, combine OLED to test the icroduino-Stations, 文件:Microduino-Stations-Text.zip Prepared hardware：Microduino FT232R, Microduino Core, Microduino-Stations, Microduino OLED； Prepared software：Microduino test program (Arduino part), Arduino IDE(1.0 release and upper); Open the example program in IDE, select the board "Microduino Core (Atmega328P@16M,5V)", download directly; After downlaod, please observe the OLED： The first line uses to test AM2321, display the temperature data； The middle line uses to test BMP180, display pressure data； The last line uses to tset TSL2561, display light intensity data.
