SHT40I-HD1F
NewAnalog humidity sensor for industrial applications with membrane
<p>The SHT40I-HD1B is an analog humidity and temperature sensor which has been specifically developed for demanding industrial applications such as refrigerator and air conditioner use cases, as well as any other application where high system noise prevents the use of digital solutions. Like the digital version, the SHT40I, the analog series offers 5 V supply voltage, robust housing and increased ESD protection to match the requirements of harsh operating environments. An optional periodic variable power heater allows for operation in highly demanding environments, including those with constant high humidity and condensing atmospheres. The integrated SHT4xI PTFE membrane provides additional protection, from particles, and supports sensor operation in harsh conditions.</p>
