7Semi SHT40I 5V Analog Output Humidity & Temperature Sensor Breakout

The 7Semi SHT40I Analog Humidity and Temperature Sensor Breakout is a compact and reliable environmental sensing module designed for accurate temperature and relative humidity measurements in industrial and embedded applications. Featuring the Sensirion SHT40I-Analog sensor, the module provides ±0.3°C typical temperature accuracy and ±2.5% RH typical humidity accuracy across a 0–100% RH measurement range.

Operating from a nominal 5 V DC supply, the breakout provides two independent analog voltage outputs for humidity (HUM) and temperature (TEM), allowing direct interfacing with microcontrollers, ADCs, data acquisition systems, and industrial controllers. Its analog interface makes it particularly suitable for applications where digital communication may be affected by electrical noise.

Its compact PCB design and simple four-pin interface enable convenient integration into HVAC systems, industrial automation, environmental monitoring equipment, IoT devices, and embedded control applications.
