Description
This module integrates DHT11 sensor and other required components on a small PCB.
The KY-015 Sensor Module combines a digital temperature and humidity sensor (DHT11) into a compact unit that’s perfect for monitoring environmental conditions in Arduino, Raspberry Pi, and microcontroller projects.
This module outputs digital readings for both temperature and humidity, making it ideal for applications like weather stations, home automation, greenhouse monitoring, and IoT projects.
It uses the reliable DHT11 sensor, which provides humidity from 20–90% RH and temperature from 0–50°C, with single-wire digital communication for easy programming.
The module is ideally suited to projects that need basic environmental monitoring in a compact and easy-to-use form factor.
