HTU31D Temperature And Humidity Sensor Module

Product Information:

The HTU31D is a digital version communication module, and this relative humidity sensor adopts surface mounting, while also providing temperature output. This sensor can provide fast response, high measurement, and low hysteresis characteristics even in temperature and humidity environments. The sensor can operate within the temperature range of -40 ° C to+125 ° C, with a typical temperature accuracy of ± 0.2 ° C. In addition, it can also measure relative humidity from 0 to, with a resolution of 0.01 and an accuracy of ± 2%.

The HTU31 sensor can operate in a voltage range of 3.3 V to 5.5 V and maintain a working current of only 450 µ A, while in sleep mode it can be as low as 0.05 µ A. This sensor complies with the AEC Q100 Grade 1 standard and is packaged in a compact 6-pin DFN package with a size of 2.5 mm × 2.5 mm × 0.9 mm 。 In addition to being able to operate normally in harsh environments, this sensor is also suitable for applications such as HVAC, home appliances, respiratory equipment, and environmental monitoring solutions.

HTU31 is designed to meet the needs of the environment and end users, and is an ideal solution for home appliances, consumer, industrial, automotive, and medical applications. The main features of this humidity and temperature sensor include:

1. Precision Engineering: HTU31 adopts precision engineering design, which can achieve linear response and achieve optimal system performance. The sensor maintains a strict linear response curve, with a humidity measurement range of (0-) and a temperature measurement range of (-40 ° to 125 ° C);

2. Fast response time: The HTU31 sensor has a humidity mold structure and a very fast response time (t63%<5 seconds). Even after condensation, the response time of the sensor can still reach t63%<10 seconds, allowing the system to maintain performance continuously.

3. High performance: The HTU31 sensor provides specific molds, a rated IP67 sealing level, and a filter that can continuously maintain performance, with low hysteresis and the ability to measure the environment (temperature and humidity) even when exposed to high temperatures, high humidity, or condensation;
