KY-015 Digital Temperature & Humidity Sensor Module (DHT11)

The KY-015 Sensor Module integrates the DHT11 digital temperature and humidity sensor with required supporting components on a compact PCB, providing a simple and reliable solution for basic environmental monitoring.

Designed for use with Arduino, Raspberry Pi, and other microcontroller platforms, this module delivers digital temperature and humidity readings through a single-wire serial interface, making it easy to connect and program for a wide range of projects.


Product Overview

  • Combines temperature and humidity sensing in one compact module

  • Uses the DHT11 digital sensor for stable and consistent readings

  • Outputs digital data via single-wire communication

  • Ideal for projects requiring basic environmental monitoring in a small form factor

Commonly used in weather stations, home automation, greenhouse monitoring, and IoT applications.
