This is Sensiron high reliable tested and proven stable temperature and humidity sensor. The SHT is fully calibrated and provide a digital and analog output with an advance series of digital humidity and temperature sensor design for long term stability and high end applications such as mobile, navigation system, environmental, automotive, industrial and home automations.


The SHT3X is a newly launch next generation of temperature and humidity sensor from Sensirions, designed in a new CMOSense core. The SHT3X has added a new intelligence platform for reliability and improved the sensing accuracy specification compared to its predecessor. The functionality includes enhance signal processing, 2 distinctive and user selectable i2C address with the communication speed of up to 1 MHz. This device driven on 2.4v to 5.5v guarantees compatibility on a assembly situations. For more reading and address selection please refer to the datasheet below.


The SHTC1 is designed to overcome the limit of size, power consumption, and performance. The Sensirions’s CMOSense technology offers a complete sensor system on a single chip consisting of a capacitive humidity sensor, a bandgap temperature sensor, analog and digital signal processing A/D converter, calibration data memory and a digital communication interface that communicate with fast mode i2C protocol. This sensor convers humidity measurement range of 0 to 100% RH and a temperature measurement’s range of -30 degree Celsius to 100 degree Celsius with accuracy of +- 0.3 degree Celsius. This device is runs on 1.8v and energy budget below 1 μJ per measurement make that make this device suitable for mobile or wireless applications running on a tightest power consumption. . For more reading please refer to the datasheet below.
