Product: SHT40 Smart Gadget

Description: The SHT4x Smart Gadget is a reference design circuit board. The Smart Gadget comes with a SHT40 humidity and temperature sensor and measures ambient humidity, temperature, and dew point in Celsius and Fahrenheit. Furthermore, it is able to communicate with Bluetooth low-energy devices, such as smartphones, while offering data-logging capabilities. The gadget consists of a main PCB equipped with an SHT40 sensor, LCD display, push-button, and BLE module, including battery, supports, and a user guide. The SHT40 builds on the CMOSens chip. Sensirion’s CMOSens technology provides a complete sensor system on a single chip, with a fully calibrated digital I2C fast-mode plus interface. The sensor covers operating ranges from 0 to 100% RH and from -40°C to 125°C with accuracies of ±1.8% RH and ±0.2°C. With an extended supply voltage range from 1.08 V to 3.6 V and 400 nA average current, the SHT40 is suited for mobile and battery-driven applications. The small size encased within a robust DFN housing enables robust integration, as demonstrated by the JEDEC JESD47 qualification. Sensirion offers the MyAmbience app for viewing live data from all gadgets or tracking history and export data.
