High Accuracy Analog Humidity And Temperature Sensing Breakout For Industrial And Embedded Monitoring Applications
This breakout board is built around the Sensirion SHT40I Analog sensor and offers separate 0 to 5 V outputs for humidity and temperature, enabling reliable measurements even in electrically noisy environments where digital sensors struggle. The analog outputs interface directly with PLC inputs, data loggers, microcontroller ADCs and industrial monitoring systems, making it a strong fit for HVAC, environmental control and automation tasks.
The compact design includes clearly labelled 2.54 mm pins for VCC, GND, HUM and TEM, ensuring quick integration with Arduino, ESP32, STM32 and similar platforms. With factory calibrated accuracy, fast response time and a wide operating range, this breakout supports ducts, enclosures, weather stations and high demand industrial applications without the need for additional calibration or shielding.
