SHT71
Obsolete±3% Digital pin-type humidity and temperature sensor
A digital pin-type relative humidity sensor for easy replaceability in a wide range of applications. The series consists of a standard version, SHT71, which convinces with its attractive price-performance ratio, and a high-end version, SHT75. A unique capacitive sensor element is used for measuring relative humidity, while temperature is measured by a band-gap sensor. The sensors integrate sensor elements and signal processing in compact format and provide a fully calibrated digital output. This results in the SHT7x humidity sensor’s easy replaceability, so that individual calibration is no longer necessary. The unique design of the SHT7x allows for the best possible thermal coupling to the environment and decoupling from potential heat sources on the main board. In combination with the individual precision calibration, the on-chip calibration memory, and the digital two-wire interface, this guarantees the best possible sensor performance in demanding applications with easy and fast system integration. The easy replaceability and low power consumption make the SHT7x humidity sensor series the ultimate choice for even the most demanding applications. The SHT7x humidity sensor series is supplied on FR4 with pins and is designed for the best possible performance. The same sensor is also available as an SMD package (SHT1x).
