SHT31-DIS digital humidity and temperature sensor

SHT31 Basic Circuit

Build a basic SHT31 circuit with labeled pins, component values and connection guidance.

SHT31 in a circuit

A physical sensor, two bus pullups and local bypassing.

SHT31 DFN connected to a 3.3 V controller with SDA and SCL pullups, 100 nF bypass, grounded ADDR and R contacts, and the ground pad connected to VSS.
Illustrative 25.00°C and 50.00%RH display at seven-bit address 0x44. ALERT and nRESET are unused.

Connect it, step by step

Follow the component values and pin connections

Power and ground

Bypass VDD, connect VSS and the center land, and keep the opening clear.

Wire the bus

Fit SDA and SCL pullups to 3.3 V and strap ADDR LOW.

Check each word

Issue the conversion command, wait, then validate temperature and humidity separately.
