Description

    The WHT 20 temperature and humidity sensor is embedded with a dual-row flat leadless SMD package suitable for reflow soldering. The temperature and humidity signals can be read out on different pins. The bottom surface is 3.0×3.0 mm and the height is 1.05 mm.

    The sensor outputs a calibrated digital signal in standard I2C format. The WHT 20 series temperature and humidity sensor uses the transistor Vbe temperature characteristic to achieve high-precision temperature detection and the dielectric constant change after the medium absorbs moisture to achieve environmental humidity detection. It is a single-chip solution combined with the latest integrated circuit signal processing technology. It has the advantages of small size, low power consumption, high reliability and good compatibility.
