It uses standard I2C, so it is simple to read from any Arduino, Linux or Raspberry Pi board, and you can take readings as often as you like. It is a tidy upgrade from DHT-style sensors for room monitors and weather projects.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMeasures temperature and relative humidity\u003c\/li\u003e\n\u003cli\u003eTypical accuracy of ±2% RH and ±0.3 °C\u003c\/li\u003e\n\u003cli\u003eStandard I2C with STEMMA QT \/ Qwiic connectors\u003c\/li\u003e\n\u003cli\u003eNo limit on how often you take readings\u003c\/li\u003e\n\u003cli\u003e3–5 V compatible\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor:\u003c\/strong\u003e Aosong AHT20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHumidity accuracy:\u003c\/strong\u003e ±2% RH typical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature accuracy:\u003c\/strong\u003e ±0.3 °C typical (20–80% RH, 20–60 °C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterface:\u003c\/strong\u003e I2C, single fixed address\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWorks with\u003c\/h3\u003e\u003cp\u003eArduino, Raspberry Pi, CircuitPython and ESP32.
