7Semi SHT41 Temperature & Humidity Sensor Breakout 1.27mm Pitch

The 7Semi SHT41 Temperature & Humidity Sensor Breakout (1.27mm Pitch) is a high-precision, ultra-compact digital sensor module designed for accurate environmental sensing. Built around the Sensirion SHT41 — part of the industry-leading SHT4x series — it provides precise measurements of temperature and relative humidity with minimal power consumption. The sensor uses a fully calibrated digital output via the I²C interface, offering superior long-term stability, fast response time, and excellent accuracy. Its 1.27 mm pitch breakout design makes it ideal for compact, space-constrained embedded and IoT applications.
