4 in stock

Overview

The SEK-SHT40I-AD1B-Sensors is an evaluation kit for the SHT40I industrial-grade digital humidity and temperature sensor. It features the SHT40I-AD1B IC mounted on a PCB with a pin header for easy integration into development environments and Sensirion SensorBridge setups. The kit provides a platform to test the sensor's wide 2.3V to 5.5V supply range and its high accuracy across industrial temperature extremes.

Why Choose This Part

The kit highlights the SHT40I's high sensitivity of +/-0.2degC and +/-1.8% RH while utilizing an integrated variable power heater for self-cleaning. It is designed for low power consumption, drawing only 21 uA at a 1 Hz measurement rate, making it suitable for battery-powered industrial IoT nodes. The hardware is JEDEC JESD47 qualified, ensuring long-term reliability in demanding industrial applications.

Applications

Industrial Process Monitoring
Reliable climate monitoring in harsh factory environments where robustness and NIST traceability are required.
HVAC System Integration
Prototyping sensor nodes for industrial heating, ventilation, and air conditioning systems with I2C communication.
Condensing Environments
Testing the sensor's ability to remain fully functional in high-humidity applications where water condensation may occur.
