## Description

The AHT20 is a high-precision but low-cost temperature and humidity sensor, which is equipped with an improved MEMS semiconductor capacitive humidity sensor element. It features standard I2C interface and a wide voltage supply of 2V-5V. And with the simple peripheral circuit, it performs stably even in harsh environments in the measuring range of -40°C ~ +85°C. This sensor can be widely used for measuring the environmental temperature and humidity of home electronic equipment, the temperature and humidity of automobiles, and so on.Connection DiagramFeaturesDigital output, I2C interfaceExcellent long-term stability Fast response, strong anti-interference, and adaptability Gravity interface, simple wiring, no soldering required ApplicationsHVACDehumidifierTesting EquipmentConsumer AppliancesAutomobilesAutomatic ControlData Loggers Weather Control SpecificationModule ParametersOperating Voltage: DC2V-5VOutput Signal: I2CI2C Address: 0x38Dimension: 30mm×20.5mm/1.18×0.81"AHT20 Chip ParametersRelative HumidityResolution: 0.024 %RHAccuracy Error: ±2 %RHRepeatability: ±0.1 %RHHysteresis: ±1 %RHNon-linear: ±0.1 %RHResponse Time: 8SOperating Range: 0~100 %RHLong-term Drift: <0.5 %RH/yrTemperatureResolution: 0.01°CAccuracy Error: ±0.3°CRepeatability: ±0.1°CHysteresis: ±0.1°CResponse Time: minimum 5S, maximum 30SOperating Range: -40°C~85°CLong-term Drift: <0.04°C/yr DocumentsProduct wikiDimensionsCircuit Diagram SCH2D Dimensions2D CAD_Dimensions3D STP Shipping ListGravity: AHT20 Temperature and Humidity Sensor × 1Gravity-4P I2C/UART Sensor Cable × 1
