Description

The SHT40 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 the 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 environments.

The board can accept a voltage of 3.3V to 5V and a current consumption below 0.15mA in low power mode. This low current requirement makes the SHT40 suitable for mobile or wireless battery-driven applications. It’s ideal for urban environment monitoring, intelligent buildings, industrial automation, smart home and other Internet of Things applications.
