Overview

The HDC2022DEPR is an integrated digital humidity and temperature sensor with an I2C interface, featuring a factory-installed IP67 rated water and dust protection cover. It is designed for high-reliability applications where environmental exposure is a concern, offering a small 3x3mm WSON footprint and operation from 1.62V to 3.6V. This sensor is backward-compatible with the HDC2080 and provides an average supply current as low as 550 nA for typical operation.

Why Choose This Part

The integrated IP67 membrane simplifies mechanical design by eliminating the need for separate protective housings while maintaining a fast 6-second response time. Its ultra-low power consumption makes it ideal for energy-harvesting or battery-operated designs, and the I2C interface supports continuous conversion or one-shot modes for flexible power management.

Applications

Industrial Environmental Monitoring
Utilizes the IP67 cover to monitor conditions in harsh industrial environments where dust and liquid ingress are possible.
Smart Home HVAC Systems
Provides precise temperature and humidity data for thermostat control and building automation systems.
Battery-Powered IoT Nodes
Leverages the extremely low 50 nA sleep current and 550 nA average run current for long-term remote monitoring.
Cold Chain Logistics
Tracks environmental conditions for perishable goods using the integrated temperature sensor and wide -40C to 125C operating range.

Getting Started

To evaluate this sensor, use the HDC2022EVM evaluation module which connects to the TI SCB controller. Software development can be handled via TI's standard I2C drivers, and engineers should ensure the I2C pull-up resistors are sized correctly for the 1.62V to 3.6V supply range used.
