Product Description: YJJ DHT21 Digital Temperature and Humidity Sensor Is Used in Air Purifiers
Features: DHT21 sensor is commonly used in graduation projects to measure the temperature and humidity data of the environment. The DHT11 sensor has a wide measurement range, capable of measuring relative humidity from 20% to 90% and temperature from 0°C to 50°C. Its humidity measurement accuracy is ±5% RH, temperature measurement accuracy is ±2°C, and the resolution is 1. This makes the DHT11 suitable for many application scenarios. Main specification parameters of the DHT21 ( AM2301 ) digital temperature and humidity sensor are as follows: Measurement range Humidity: 0 - 99.9% RH Temperature: -40℃ ~ +80℃ Accuracy and Resolution Humidity: ±3% RH Temperature: ±0.5℃ Resolution: Humidity 0.1% RH, Temperature 0.1℃ Power Supply and Communication Voltage: 3.3V to 5.5V (typical operating voltage 3.3V) Power consumption: Approximately 500 μA (supply current) Interface: Single bus interface (requires only one data line) Storage conditions Recommended storage temperature range: 10℃ to 50℃, humidity 20% to 60% RH. This is to prevent component performance from drifting.
Typical application Suitable for scenarios such as air purifiers, humidifiers, dehumidifiers, environmental monitoring equipment, etc.
