Temperature and Humidity Sensor Module KY-015

The KY-015 temperature and humidity sensor unit (based on the DHT11 sensor) is a common and low-cost solution for measuring ambient temperature and relative humidity in the air. It is widely used in simple weather stations, climate control systems, and environmental monitoring projects. The unit provides a digital output that sends temperature and humidity data serially, and can be easily read using microcontrollers and ready-made software libraries. Technical details: Unit model: KY-015 (DHT11) Operating voltage: 3.3 to 5 volts Temperature measurement range: 0-50 degrees Celsius (accuracy ±2°C) Humidity measurement range: 20-90% RH (accuracy ±5%) Interface: 1-Wire (custom)
