HTU31D for the digital version of the communication module, the relative humidity sensor USES surface-mount, at the same time can also provide temperature output.The sensor even in extreme temperature and humidity environment, also can provide fast response, high precision measurement and low hysteresis characteristics.Sensors can be in to 40 ° C to + 125 ° C temperature within the scope of work, the typical temperature accuracy of + / - 0.2 ° C.In addition, it also can measure 0 to 100% relative humidity, resolution of 0.01, accuracy of + / - 2%.

HTU31 sensor to voltage of 3.3 V to 5.5 V within the scope of work, and can maintain only 450 (including A working current, dormancy mode is as low as 0.05 (including A, using compact 6 pins DFN encapsulation, size of 2.5 mm x 2.5 mm x 0.9 mm.In addition to the normal operation in harsh environment, the sensor is suitable for use in HVAC, electrical appliances, breathing apparatus, and environmental monitoring application solutions.
HTU31 designed to meet the demands of the environment and the end user, for home appliances, consumer, industrial, automobile and medical applications, is an ideal solution.The humidity and temperature sensor's main features include:
1, precision engineering: HTU31 adopts precision engineering design, can achieve linear response, thus make the system to achieve optimal performance.The sensor keep strict linear response curve, humidity measurement range (0-100%), the temperature measurement range for (- 40 ° to 125 ° C).
2, fast response time: HTU31 sensors have humidity mold structure, the response time is very fast (t63 %
3, high performance: HTU31 sensors provide specific mold, and rated IP67 sealed level, also have a filter, can continue to maintain performance, low hysteresis sex, even when exposed to high temperature, high humidity or condensation, is still able to accurately measure the environment (temperature and humidity);
