SHT40-AD1F
New±1.8% RH humidity sensor with membrane / 0x44 I2C Output
<p>In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT40-AD1F offers the best price-performance ratio on the market. Tape and reel packaging combined with its suitability for standard SMD assembly processes make the SHT40-AD1F ideal for high-volume applications. </p><p> </p><p>The SHT40-AD1F builds on a completely new and optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications. With the extended supply voltage range from 1.08 V to 3.6 V, it’s the perfect fit for consumer and battery-driven applications. The integrated SHT40-AD1F PTFE membrane provides additional protection from particles, and enables sensor operation in harsh conditions. On top of that, the SHT40-AD1F is compliant with the relevant healthy building standards RESET® and WELL Building Standard™.</p>
