The Digital output is for a I2C interface in a 14 bit resolution. Accuracy at 23 °C is +/- 1.8 % RH in the span of 0 % RH to 80 % RH. This reading comes with a Response time of less than 4 seconds.
They also have a LabKit with USB Interface to evaluate and implement in your system.
“The Labkit was developed as a Plug&Play tool for a fast evaluation of the HYGROCHIP digital humidity sensors. The ready-to-use system consists of a PC-adapter with an USB connecting wire, a connection adapter with plugs for all product variants.”
Component level. manufacturer of thin-film RTD temperature sensors, capacitive humidity sensors, mass flow sensors and conductivity sensors.
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.
