MEMS type Temperature and Humidity Sensor WHT30
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
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.
