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.
