HTU21D

This is an Arduino library for SHT21, HTU21D & Si70xx Digital Humidity and Temperature Sensor

Supports all sensors features:

  • read humidity for SHT21, HTU21D or compensated humidity for Si70xx
  • calculate compensated humidity for SHT21, HTU21D
  • read temperature for SHT21, HTU21D, Si70xx or retrieve temperature value after RH measurement for Si70xx
  • soft reset
  • check battery status
  • turn ON/OFF build-in Heater
  • read FW version
  • read sensor ID

Tested on:

  • Arduino AVR
  • Arduino ESP8266
  • Arduino STM32
