Digital Humidity Sensor SHT1x (RH/T)
Not Recommended for New Designs (NRND)
SHT1x will reach end-of-life and is only available to existing customers for support of their running production.
Last order date: 31.12.2018 / Last delivery date: 31.12.2019
Replacement: We recommend the humidity sensor SHT3x as successor of SHT1x. SHT3x offers a wide range of communication protocols, advanced performance as well as additional features.
The SHT1x digital humidity sensor is a reflow solderable sensor. The SHT1x series consists of a low-cost version with the SHT10 humidity sensor, a standard version with the SHT11 humidity sensor, and a high-end version with the SHT15 humidity sensor. As with every other Sensirion sensor type from the SHTxx humidity sensor family, they are fully calibrated and provide a digital output.
The SHT1x humidity sensor series (including SHT10, SHT11, and SHT15) is Sensirion’s family of surface-mountable relative humidity sensors. The humidity sensors integrate sensor elements plus signal processing on a tiny footprint and provide a fully calibrated digital output. A unique capacitive sensor element is used for measuring relative humidity, while temperature is measured by a band-gap sensor. Its CMOSens® technology guarantees excellent reliability and long-term stability. The humidity sensors are seamlessly coupled to a 14-bit-analog-to-digital converter and a serial interface circuit. This results in superior signal quality, a fast response time, and insensitivity to external disturbances (EMC).
Each SHT1x humidity sensor 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 two-wire serial interface and internal voltage regulation allows for easy and fast system integration. SHT1x is supplied in a surface-mountable LCC (leadless chip carrier), which is approved for standard reflow soldering processes. The same sensor is also available with pins (SHT7x).
