DHT11 Sensor Digital Temperature and Humidity Sensor

Description DHT11 is a temperature and humidity sensor on the single chip. The sensor is a low cost basic digital temperature and humidity sensor. To sense humidity and temperature, it uses a capacitive humidity sensor and a thermistor respectively. It measures the surrounding environment and gives a digital signal at its data pins. As it does not require any analog pin or data, so it’s easy to use, but need to be careful with timing to get data. Specification Voltage supply: 3-5V Maximum current during conversion: 2.5mA Humidity reading: 20-80% Humidity accuracy: 5% Temperature reading: 0-50°C Temperature accuracy: ±2% Sampling rate: 1Hz once every second Pin Description Vcc: 3V to 5V Signal: Data NC: Not Connected Gnd: Ground
