SEK-SHT40I-HD1B-Sensors

Overview

The SEK-SHT40I-HD1B-Sensors is an evaluation and development accessory featuring the SHT40I industrial humidity and temperature sensor. It is designed to plug directly into Sensirion's Sensor Evaluation Kit (SEK) to provide analog voltage outputs for relative humidity and temperature monitoring. This tool allows engineers to test the sensor's performance in harsh environments, utilizing its integrated heater and robust 5V-tolerant interface.

Why Choose This Part

This component offers an industrial-grade 4.5V to 5.5V operating range with a 5V-tolerant IO, making it compatible with legacy PLC and industrial controller inputs. It maintains high accuracy of 2.5 percent relative humidity while offering a built-in variable power heater to clear condensation from the sensor element.

Applications

Getting Started

Connect this sensor board to the Sensirion SEK-ControlCenter viewer software via an SEK-Bridge for immediate data visualization. For custom hardware integration, reference the standard ARP analog output characteristic to map the voltage levels to humidity and temperature values. Ensure the power supply is stable within the 4.5V to 5.5V range for optimal analog accuracy.
