5pcs AHT20 Precision Digital Temperature Humidity Sensor Measurement Module I2C IIC Communication Compatible SHT20 Temperature -40 to +120°C Humidity 0 to 100%RH 2.2 to 5.5V 400KHz SMD
- 5-piece AHT20 sensor module set provides calibrated digital temperature and humidity signals for measurement applications.
- Measures temperature across a -40 to +120°C range and relative humidity from 0 to 100%RH.
- Temperature accuracy is specified as ±0.3, while humidity accuracy is specified as ±2%RH at 25.
- Uses standard I²C/IIC communication with a stated clock frequency of 400KHz for digital output.
- Supports a 2.2 to 5.5V supply voltage, with 3.3V recommended for module operation.
- The dual-row, flat, pinless SMD package measures 3.0 x 3.0 x 1.0 mm for compact circuit placement.
- The SMD package is suitable for reflow soldering during board assembly.
- For storage after opening, use an ESD metal PET/AL/CPE pocket inside an anti-static bag at 10-50°C and 20-60% RH.
- Avoid prolonged exposure to high concentrations of chemical vapors, which can cause sensor readings to drift.
- After extreme exposure, the stated recovery process uses drying at 80-85°C for 10 hours below 5% RH, followed by rehydration at 20-30°C for 24 hours above 75% RH.
