Sensor-Temp&Hum The product number of Sensor-Temp&HumS2 is: MSDT31. Sensor-Temp&Hum is a temperature and humidity detection sensor module. SHT20 sensor contains a capacitive humidity component and a high precision integrated temperature measuring component, and it is conencted with a high performance microprocessor. Instruction of Sensor Pin Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx. Special to Sensor-Tem&Hum-S2 sensor pins PIN1: GND PIN2: VCC PIN3(IO1): SDA PIN4(IO2): SCL Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub. Features Adopts SHT20 temperature and humidity sensor With high accuracy and sensitivity With low power consumption, long service life and good stability With wide working voltage With small size which is easy to install Specification Electric specification Working voltage: 3.3~5V Size of the sensor Size of the board: 23.5mm*13mm 1.27mm-spacing 4Pin interface connected to sensorhub The CAD drawing of the sensor: File:Sensor CAD.zip Technical parameters Resolution: temperature 0.1°C, and relative humidity 0.1%RH Connection This sensor can be connected to I2C pin of core Document Schematic diagram: File:Sensor-Temp&HumS2.Zip Main chip: File:ST20 datasheet.pdf Development Program Download Download and unzip the program File:Sensor-Tem&Hum S2 Test.zip Programming Follow the Software Getting Started Guide.
