Digital Humidity and Temperature Sensor SHT71

Versatile and Replaceable Digital humidity sensor, a cost-effective component. In the SHT family the capacitive humidity sensors are fully calibrated and provides a digital output ready for interface.

Each SHT7x is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to internally calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows for easy and fast system integration.

The power consumption of around 80uW makes it ideal for battery operated devices. It measures the full span of  0-100% RH with a response time of 8 sec. The temperature range being -40 – +125°C.

SCK is used to synchronize the communication between microcontroller and SHT7x. The DATA tri-state pin is used to transfer data in and out of the sensor.

Sensirion is the leading manufacturer of high-quality sensors and sensor solutions for the measurement and control of humidity, and of gas and liquid flows.
