The SHT4X is the 4th generation digital temperature and humidity sensor from Sensirion. In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT40 offers consistent high accuracy within measuring range.

The SHT40 sensor covers a humidity measurement range of 0 to 100%RH and a temperature detection range of -40°C to 125°C with a typical accuracy of ±1.8％RH and ±0.2℃. The internal variable power heater enables the device to work properly under extreme operating conditions like condensing environment.

The board supply voltage of 3.3V to 5V and an current consumption below 0.15mA in low power mode make the SHT40 perfectly suitable for mobile or wireless battery-driven applications. It is suitable for urban environment monitoring, intelligent buildings, industrial automation, smart home and other Internet of Things applications.
