  • The DHT21 temperature and humidity sensor is an advanced sensor unit that outputs a calibrated digital signal. It is highly reliable and stable in long-term operation. It contains an 8-bit microprocessor, giving fast and high quality response.

    The unit, which measures temperature with an error margin of +/-1°C between -40 and 80°C, can measure humidity with an error margin of +/-5% RH between 0-100% RH. As a sensor measurement, measurement results can be obtained in 2-second periods due to the datah collection period of the sensor. The DHT21 is slightly larger in size than other DHT models.

    Features:
    It is one of the high performance models of the DHT series.
    It gives digital output.
    Operating Voltage: 3.3-5 VDC
    Measuring Range:
    Humidity: 0-100%RH
    Temperature: -40 - 80 °C
    Sensibility:
    Humidity: +/- 3% (Max 5%) RH
    Temperature: < +/- 1°C
    Measurement Period: 2 s
    Product Dimensions: 27x59x13.5 mm
