Temp Sensor SHT31x

The Temp Sensor SHT31x is a digital temperature and humidity sensor based on the Sensirion SHT31. It measures both air temperature and relative humidity with high accuracy and sends the readings over I2C, so it connects to an Arduino, ESP32, ESP8266 or Raspberry Pi with just power, ground and two data lines. It is a good upgrade from the DHT11 and DHT22 for weather stations, greenhouses and room monitors.

Temp Sensor SHT31x Specifications

• Sensor: Sensirion SHT31 (SHT3x series)
• Measures: temperature and relative humidity
• Temperature accuracy: typically ±0.3 °C
• Humidity accuracy: typically ±2 %RH
• Ranges: −40 to 125 °C and 0–100 %RH
• Interface: I2C, address 0x44 (0x45 with the ADDR pin high)
• Supply voltage: 2.4–5.5 V for the sensor chip, suits 3.3 V and 5 V boards

Temp Sensor SHT31x Applications

• Weather stations and indoor climate monitors
• Greenhouse, incubator and storage room monitoring
• Smart home and IoT projects with ESP32 or ESP8266
• HVAC, dehumidifier and fan control

What's in the Box

• 1 × SHT31x temperature and humidity sensor

Tip: Use a library such as Adafruit SHT31 and connect SDA and SCL to your board's I2C pins. Mount the sensor away from regulators and other warm parts, and avoid touching it, so that heat does not affect the readings.
