DHT 11 Humidity & Temperature
Sensor
1. Introduction
This DFRobot DHT11 Temperature & Humidity Sensor features a temperature & humidity sensor
complex with a calibrated digital signal output. By using the exclusive digital-signal-acquisition
technique and temperature & humidity sensing technology, it ensures high reliability and
excellent long-term stability. 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.

DHT11
Each DHT11 element is strictly calibrated in the laboratory that is extremely accurate on
humidity calibration. The calibration coefficients are stored as programmes in the OTP memory,
which are used by the sensor’s internal signal detecting process. The single-wire serial interface
makes system integration quick and easy. Its small size, low power consumption and up-to-20
meter signal transmission making it the best choice for various applications, including those
most demanding ones. The component is 4-pin single row pin package. It is convenient to
connect and special packages can be provided according to usersrequest.
