DHT11 Sensor Features The DHT11 is a digital temperature and humidity sensor. This sensor is able to measure the humidity in the range of 20% to 80% with an accuracy of 5%. It can also measure the temperature in the range of 0 to 50 degrees Celsius with an accuracy of 2 degrees. Note The sampling frequency of this sensor is 1Hz. As a result, there must be at least one second between every readings of the sensor, otherwise the reading values will be incorrect. ...

DHT22 Temperature Humidity Sensor Features The DHT22 Temperature Humidity Sensor is a great choice for measuring ambient temperature and humidity. This sensor consists of a capacitive humidity sensor and a heat resistor. The DHT22 sensor has a wide range of temperature and humidity measurement. It can measure temperature in range of -40 to +125 degrees Celsius with 0.5 degrees Celsius accuracy. Humidity is measured in range of 0 to 100% with 2.5% accuracy. This sensor transmits data through a single di...

DHT21/AM2301 Temperature and Humidity Sensor Features The AM2301 / DHT21 temperature and humidity sensor consists of two sensors: A capacitive humidity sensor and a thermistor. This sensor transmits data using a single digital pin, so it can communicate with the microcontroller using only one digital pin. The sampling frequency is 0.5Hz, which means that you can get new data every two seconds. DHT21/AM2301 Temperature and Humidity Sensor Pinout This Module has 3 w...

What is AM2301 Sensor? The AM2301 module is an internally-calibrated digital sensor that measures temperature and humidity. It can measure humidity from 0 to 99.9% with an accuracy of ±2% and temperatures from -40 to 80°C with an accuracy of ±3°C.This digital module uses a single-wire protocol for communication. So, apart from the power supply pins, it only needs one digital pin to communicate with the microcontroller. Using this protocol, we can transfer data through this line for a maximum distanc...
