                      Product Overview

                      SHT40-AD1F-R2 is a SHT4x series industry-proven digital humidity and temperature sensor. Its suitability for standard SMD assembly processes make the SHT4x series ideal for high-volume applications. It builds on a completely new and optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications. The integrated SHT40 PTFE membrane provides additional protection from particles and enables sensor operation in harsh conditions. Applications include industrial applications, HVAC, appliance (refrigerator, air purifier, tumble dryer, washing machine), outdoor and food sector.

                      • Digital humidity and temperature sensor with typical ±1.8% / max. ±3.5% RH, I2C 0x44
                      • Enhanced protection against dust and water, no sensing performance impact
                      • Additional contamination hinderance
                      • Robust and durable design allows application in very demanding environments
                      • Additional protection may allow prolonged sensor lifetime
                      • Cost-effective SMD assembly
                      • No additional production process steps necessary
