Boardoza SHT31 Analog Humidity and Temperature Sensor Breakout Board

Boardoza SHT31 is a compact 20 × 20 mm temperature & humidity sensor board built around Sensirion’s SHT31 platform. The sensor provides a fully calibrated, linearized, and temperature-compensated analog output, designed for stable, repeatable measurements across applications.

Unlike typical digital-only sensor breakouts, the SHT31 exposes two separate analog outputs—T (temperature) and RH (relative humidity)—so you can measure both signals in parallel with standard ADC inputs, without I²C configuration or bus constraints.

The outputs are ratiometric analog voltages (10% to 90% of VDD), and the mapping from physical values to voltage is handled internally with compensation and per-device calibration—meaning the voltage-to-value relationship is consistent within the stated accuracy limits.

Designed for broad compatibility, the sensor operates from a wide 2.4 V to 5.5 V supply range and offers typical accuracy of ±2%RH and ±0.3°C.

For robust embedded integration, the device also provides an active-low nRESET input (useful for controlled startup and recovery).

Ideal use cases: HVAC controllers, dataloggers, industrial monitoring, test fixtures, and mixed-signal systems where clean analog interfacing and parallel T/RH acquisition are preferred over digital buses.
