5pcs AHT20 Precision Digital Temperature Humidity Sensor Measurement Module I2C IIC Communication Compatible SHT20

The AHT20 temperature and humidity sensor is embedded in a dual-row flat pinless SMD package suitable for reflow soldering, and the sensor outputs a calibrated digital signal in standard I²C format Temperature measurement range: -40~+120°C Supply voltage: 2.2~5.5V Temperature accuracy: ±0.3℃ Size: 3.0X3.0X1.0 mm Apparent degree measuring range: 0~100%RH Humidity accuracy: ±2%RH(25℃) Output signal: I²C Module operating voltage: recommended 3.3V IIC clock frequency: 400KHz Humidity sensors are not ordinary electronic components and require careful protection, which must be taken seriously by the user. Prolonged exposure to high concentrations of chemical vapors will cause the sensor's readings to drift. For those sensors that have been removed from their original packaging, we recommend that they be stored in an ESD pocket made of metal PET/AL/CPE in an anti-static bag that meets the following conditions: Temperature range of 10°C-50°C (0-85°C for a limited period of time) Humidity of 20-60% RH. Recovery Processing: If the sensor is exposed to extreme operating conditions or chemical vapors, readings will drift. Readings may drift if the sensor is exposed to extreme operating conditions or chemical vapors, as described above. It can be returned to calibration by the following treatment. Drying:10 hours at 80- 85 degrees Celsius and <5% RH humidity; Rehydration:24 hours at 20- 30 degrees Celsius and >75% RH humidity. Temperature Effects: The relative humidity of a gas is, to a large extent, dependent on temperature. Therefore, when measuring humidity, it should be ensured that all sensors measuring the same humidity are operating at the same temperature as far as possible. When making a test, ensure that the sensor under test and the reference sensor are at the same temperature and then compare the humidity readings.
