Product description: Fermion - SHT40 I2C temperature and humidity sensor - DFRobot SEN0428
A module from the Fermion series by DFRobot featuring the Sensirion SHT40 temperature and humidity sensor. The SHT40 sensor measures humidity from 0% to 100% RH with an accuracy of ±1.8% RH and temperature from -40°C to 125°C with an accuracy of ±0.2°C. A built-in variable-power heater enables proper operation in extreme conditions, such as condensing environments. The module uses an I2C interface for communication, is powered from 3.3 V to 5 V and consumes up to 0.15 mA in low power mode. The module is ideal for battery-powered mobile and wireless applications. It can be used for urban environmental monitoring, smart buildings, industrial automation and other Internet of Things applications.
