Product Description
The Sensirion SHT4xI series digital output temperature and humidity sensor, model SHT40-AD1B-R2, is designed for surface mount applications offering precise environmental measurements with minimal power usage. Operating from a supply voltage of 1.08V to 3.6V, the sensor efficiently measures relative humidity across 0 to 100%, with a temperature range capability from -40°C to 125°C. Its compact 4-pin DFN package, measuring 1.5mm length, 1.5mm width, and 0.55mm height, allows integration into space-constrained electronic devices.
This fourth-generation sensor provides calibrated and linearized digital data via a fast I2C interface, enabling seamless communication with microcontrollers and systems in diverse industrial, HVAC, manufacturing, agricultural, and laboratory equipment contexts. The ultra-low average current consumption of around 0.6 microamps supports long-term operations in battery-powered or energy-sensitive environments. Additionally, a variable power heater is integrated to maintain sensor performance by preventing condensation or contamination.
Engineered in Switzerland, the SHT4xI sensor series does not include specific automotive standards but offers robust performance for commercial electronic applications. Its reliable and precise measurements facilitate optimal environmental monitoring and control in automated systems requiring humidity and temperature sensing.
Measures relative humidity from 0 to 100% with high precision. Operates in temperatures ranging from -40°C to 125°C. Low supply voltage range between 1.08V and 3.6V supports versatile device integration. Utilizes I2C fast mode plus interface for efficient communication.
