Sensirion SHT4x Digital Sensors with Protective Film
Sensirion SHT4x Digital Humidity and Temperature Sensors with Protective Film are equipped with an I2C standard interface and a fixed 0x45 I2C address. These fourth-generation sensors offer ±1.8%RH and ±0.2°C accuracy. The SHT4x sensors include a power-trimmed internal heater that can be used at three heating levels, enabling seamless sensor operation. These sensors are ideal for Surface Mount Technology (SMT) processing and comply with JEDEC JESD47 standards. The SHT4x sensors are used in applications such as Heating, Ventilation, and Air conditioning (HVAC) and manufacturing processes that require protection in the sensing element.
