The KY-015 Temperature and humidity sensor module is part of the "37 In 1 Sensor Module Board Set Kit For Arduino" series, looks like a small circuit, on it are mounted, the DHT11 sensor, a resistance and a pinstrip with 3 pin.
For more information see https://win.adrirobot.it/sensori/37_in_1/KY-015-Temperature-and-humidity-sensor-module.htm
ESP12F based board with 4 relays, DHST and/or LM35 temperature sensor(s) for Local or remote temperature measurment. Sockets for clock based modules based on DS1307 or DS3221 clock chips for time tracking. Additional I2C ports provide expandability to I2C displays or other sensors.
Great platform for building web based switches and monitoring temperatures and other sensors and login with RTC chips...
this is simple project that collect temperature and humidity from DHT11 or DHT22 and broadcast it in the network using protocol UDP

AC Fan Seed Controller with DHT22 (or DHT11) Temp sensor and LCD Display of Temp. UART or I2C options for 16x2 LCD diplay shown. Uses External 240V to 12V DC PSU to provide power to the Arduino Vin pin and the 5V output from the Arduino to provide power for the DHT22 and ZC Probe.
Solution to create home network via nrf24 and arduino.
Plus LEDcontrol, DHT11(temperature sensor), IR control, button control, IR motion Sensor.
