Sensirion’s Smart Gadget shows relative humidity and temperature values on the display, and can also communicate wirelessly with a Bluetooth Smart capable device, such as a smartphone or tablet. It is intended to assist developers to begin projects with an environmental sensor, Bluetooth connectivity, and corresponding apps. The Smart Gadget includes an onboard SHT31 humidity and temperature sensor, LCD driver and display, and Bluetooth module. The LCD screen displays relative humidity (±2% accuracy), dew point, and temperature in Celsius (accurate to 0.3 degrees) or Fahrenheit (accurate to 0.5 degrees).
The Smart Gadget supports two debug interfaces as well as I ²C and SPI protocols. Developers can also take advantage of the device’s complete hardware, firmware, and software resources. For further connectivity, developers can use the available apps for both iOS and Android devices.
The SHT3x series humidity and temperature sensors are based on Sensirion's CMOSens technology, which combines the environmental sensor and processing electronics on a single chip, resulting in higher system integration, as well as accurate measurements with long term stability over the sensor's operating conditions.
