HALJIA Expansion Board Module 9 in 1 Multifunction DHT11 Humidity Sensor and LM35 Temperature Buzzer Compatible with Arduino UNO R3

Nine kinds of functions concentrated in this one module shield: DHT11 Temperature Humidity Sensors, Passive buzzer, Brightness sensor, LM35D temperature sensor, Full color LED module, 2-way button module, 2-way LED module, Infrared receiver module, Rotary potentiometer module. A board integrates a variety of module functions, fully compatible with Ard UNO R3 interface, provides the basic experimental module for Ard beginners introduction. No welding, no connection, you can complete the experiment by downloading the program directly. All module code library files are provided, all tested and can be used directly. Set aside the expansion port, you can complete other modules experiments. The high row pin design will avoid contact with USB port of the UNO board, so prevent from occur short circuit.
