DHT11 - Humidity and Temperature Sensor
For more products visit our website Document: Datasheet Date: 20-Jun-12 Model #: 3732 Product's Page: DHT11 - Humidity and Temperature Sensor The DHT11 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). 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. Features Full range Temperature compensated Relative Humidity and Temperature measurement Calibrated digital signal Outstanding long-term stability Extra components not needed Long transmission distance Low power consumption 4 pins packaged and fully interchangeable Details This Sensor includes a resistive-type Humidity measurement component and an NTC Temperature measurement component, and connects to a high-performance 8-bit microcontroller, offering excellent quality, fast response, anti-interference ability and cost-effectiveness.
