Digital Humidity and Temperature Sensor, I.C 21D RH/T B5000, HPP845E031R5 (CAT#: STEM-W-0265-ZJF)

The HTU21D(F) is a digital humidity and temperature sensor for OEM applications. Setting the standard in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a small 3 x 3 x 0.9 mm footprint. This sensor provides calibrated, linearized signals in digital, I²C format. HTU21D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the module for humidity and temperature digital outputs. These low power sensors are designed for high volume and cost sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip – which can be read out by command. Low battery can be detected and a checksum improves communication reliability. The resolution of these digital humidity sensors can be changed by command (8/12bit up to 12/14bit for RH/T).
Whether it's an altimeter in a wearable band counting daily steps or a sports watch tracking a mountain ascent, our miniature sensors provide vital data for daily life. From dive computers enhancing safety during leisure activities to piezo films monitoring sleep, heart rate, and breathing, STEMart has been at the forefront of sensor innovation long before wearables became mainstream. Known for our expertise in miniaturization, low power consumption, and high performance, our sensors are trusted in extreme conditions—from high-altitude jumps to deep-sea dives.
