DHT11 Digital Humidity Temperature Sensor for Arduino Raspberry Pi 2 3 DIY (Set of 2)

This sensor module utilizes DHT11 as the sensitive component and has a bypass capacitor and a pull-up resistor on-board The DHT11 is a pre-calibrated digital output temperature and humidity sensor. The single-wire wiring scheme makes it easy to be integrated to other applications. The simple communication protocol greatly reduces the programming effort required. These are bare temperature and humidity sensors. They are pinned Vcc, Data, NC (no connection), Gnd. They give readings roughly once per minute and are fairly accurate as they are factory calibrated. Output range: 20-90% humidity, 32-122 degrees F. It is inaccurate at either end of the spectrum, works pretty well in the middle of its range. Features: Digital output Single-wire communication Laboratory pre-calibrated Stable and long-term accuracy 3-pin interlock connector Low power consumption and compact size Long transmission distance, up to 100 meters Widely used in the heating ventilation air conditioning, humidity adjuster, etc Parameters: Operating Voltage: DC 3.3V-5.5V Humidity Measurement Range: 20%-95%RH Humidity Measurement Accuracy: +/-5%RH Temperature Measurement Range: 0 ~ 50 C Temperature Measurement Accuracy: +/-2 Response Time: Less than 5s PIN1-VDD: Power on 3.3V ~ 5.5V DC PIN2-DATA: Signal output PIN3-NC: NULL PIN4-GND: External connection GND Applications: HVAC Testing and inspection equipment Automotive Data logger Consumer goods Automatic control Weather station Home appliances Humidity regulator Medical Dehumidifier Package List: 2 x DHT11 sensor
