  • WHT30.png

Summary:

The WHT30 humidity sensor is filled in a double-row flat lead-free SMD package, temperature and humidity signals can be read out on different pins, bottom side 2.5×2.5 mm, height 1.0 mm. The sensor outputs a standard digital signal,Standard I2C format.
WHT30 humidity sensor, contains a newly designed ASIC dedicated chip built-inTransistor Vbe temperature characteristics, actual high temperature temperature detection;Humidity-capacitating chip, in which the humidity-sensitive material introduces electric constant after absorbing moisture to detect the humidity in the real environment Measurement. A dual-chip solution combined with the latest integrated circuit signal processing technology case. It has the advantages of small size, low performance, high reliability, and good compatibility.     

Application
Home appliance fields: home appliance, humidity control, HVAC, dehumidifiers, smart thermostats, and room monitors etc ;
Industrial fields: automobiles, testing equipment, and automatic control devices;
Other fields: data loggers, weather stations, medical and other related temperature and humidity detection devices.

Feature:

* High accuracy ±3.0% RH and ±0.5℃ 
* Wide power supply voltage range, from 2.0V to 5.5V
* SMD package suitable for reflow soldering
* Quick response and strong anti-interference ability
* Excellent long-term stability under high humidity condition

APPLICATION

Indoor Air Quality Monitoring

The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.
