SHT31

Quick Decision Notes

SHT31 is indexed as a sensors part from Sensirion. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Pinout Table

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

Arduino Example

#include <Wire.h>

void setup() {
  Serial.begin(115200);
  Wire.begin();
  Serial.println("SHT31 I2C wiring smoke test");
}

void loop() {
  // Replace this with the maintained SHT31 library call.
  Serial.println("Check SHT31 on the I2C bus, then read a sample.");
  delay(1000);
}

MicroPython Example

from machine import Pin, I2C
import time

i2c = I2C(0, scl=Pin(1), sda=Pin(0), freq=100000)
print("SHT31 I2C devices:", i2c.scan())

while True:
    # Replace with the maintained SHT31 driver call.
    print("read SHT31 sample")
    time.sleep(1)
