Arduino Uno R3

Arduino UNO in Bangladesh The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.

Description

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It's fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

 

  • Power supply: 3- 5V.
  • Current: 2.5mA max use of current during conversion (while requesting data).
  • Humidity: 0 - 100%, ± 2%.
  • Temperature: -40°C + 125°C, ± 0.5%.
  • The sampling rate no more than 0.5 Hz (once every 2 seconds).
