Description ReviewsThe DHT-22 (also known by AM2302) is a digital temperature and humidity sensor module that works with all of the Arduino micro-controllers. 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). Its 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.Simply connect the red 3-5V power, the yellow wire to your data input pin and the black wire to ground. Although it uses a single-wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin! Features:Sensor is composed of a resistive humidity sensing component and an NTC temperature testing component and connects with 8-byte MCUMCU outputs a digital codeFast response and great anti-interference capabilityDurable and long lasting sensorLow power consumptionBased on the DHT22 & AM2302 sensor architecture Specifications:Operating Voltage: DC 3.3 – 5VCurrent: Max. 2.5mAHumidity Measurement range: 0% ~100% | ±2-5%RHTemperature Measurement range: -40℃~80℃ | ±0.5 ℃Sampling rate: 0.5Hz every 2 secondsConnections; GND, Vcc, and Signal4.2 cm x 1.5 cm x 10.0 cmWeight 7.0g SKU: Humidity & Temperature Wide Detection Range Sensor Module DHT22 Categories: Accessories, Accessories, Sensors Tags: Accessories, components, dht22, electrical, electrical components, electronics, electronics components in Patna, electronics components near me, electronics components online store, electronics components price list, electronics components store, electronics components symbols, electronics store near me, ic online store in India, ic., innovations, integrated circuit, Integrated Circuit online store, iotronics, iotronics innovations, Mobile Accessories, online store of transistor, temperature sensor, the best place to buy electronic components online in india, transistor price, where to buy electronics components in Allahabad, where to buy electronics components in Delhi, where to buy electronics components in India, where to buy electronics components in Patna
