SENSHT31-ARP-B
Overview
The SHT31-ARP-B is an analog humidity and temperature sensor that provides linearized voltage outputs for easy integration with analog-to-digital converters and microcontrollers. Operating over a 2.4V to 5.5V range, it delivers high reliability and long-term stability with a humidity accuracy of +/-2% RH. This sensor is specifically designed for systems where digital communication interfaces like I2C are not available or preferred.
Why Choose This Part
The SHT31-ARP-B features temperature-compensated analog outputs, eliminating the need for complex software compensation algorithms. Its wide operating temperature range of -40degC to 125degC and 8-second response time make it suitable for demanding environmental conditions where fast, accurate linearized voltage signals are required.
Applications
Key Specifications
Getting Started
To evaluate this sensor, connect the analog output pins directly to a microcontroller ADC input or a high-impedance buffer. Ensure the 2.4V to 5.5V supply is stable, and refer to the 26mV/%RH sensitivity specification for scaling your software routines. For prototyping, look for SHT3x breakout boards that support the analog output variant.
