SHT31-ARP-B2.5kS
Overview
The SHT31-ARP-B2.5kS is a high-accuracy humidity and temperature sensor from Sensirion featuring a linearized analog ratiometric voltage output. Built on the CMOSens technology platform, it integrates a capacitive humidity sensor and a bandgap temperature sensor into a compact 8-pin DFN package. It is designed for applications requiring high reliability and precision in a wide operating voltage range of 2.15V to 5.5V.
Why Choose This Part
This sensor offers a high resolution of 14 bits and a fast start-up time for rapid measurements. Its fully calibrated and linearized output simplifies system design by removing the need for complex software compensation. The ultra-low sleep current of 0.2uA makes it exceptionally well-suited for battery-powered remote sensing nodes.
Applications
Getting Started
To integrate this sensor, connect the VDD and VSS pins to a stable power source between 2.15V and 5.5V, and interface the analog output pins directly to a microcontroller ADC. Use the provided ratiometric formulas in the datasheet to convert voltage levels to humidity and temperature values. Evaluation can be performed using Sensirion's SEK-SHT31-ARP-Sensors kit.
