DHT21 Heat and Humidity Sensor - AM2301
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 studies. It contains an 8-bit microprocessor and provides fast and high-quality response.
The unit measures temperature between -40 and 80°C with an error margin of +/-1°C, 0 It can measure humidity between -100% RH with +/-5% RH margin of error. As a sensor measurement, measurement results can be obtained in 2-second periods due to the data collection period of the sensor. DHT21 is slightly larger in size than other DHT models.
Features:
- It is one of the high-performance models of the DHT series.
- Provides digital output.
- Operating Voltage: 3.3-5 VDC
- Measurement Range:
- Humidity: 0-100%RH
- Temperature: -40 - 80 °C
Sensitivity:
- Humidity: +/- 3% (Max 5%) RH-
- Temperature: < +/- 1°C
- Measurement Period: 2 s
Product Dimensions: 27x59x13.5 mm
NTC temperature sensor card is a module on which resistor connections have been made and which has been turned into a card for convenient supply and signal output. Analog output can be easily obtained thanks to the pins drawn on the card.
This sensor can be easily used in projects such as heat measuring devices, thermostats, room temperature measurement and smart home systems. It can be used with many microcontroller systems, especially
