Operating specification(1) Power and PinsPower's voltage should be 3-5.5V DC. When power is supplied to sensor, don't send any instruction to the sensor within one second to pass unstable status. One capacitor valued 100nF can be added between VDD and GND for power filtering.(2)Communication and signal Single-bus data is used for communication between MCU and DHT11.Small size & low consumption & long transmission distance enable DHT11 to be suited in all kinds of harsh application occasions.

Packing Included:1 x DHT11 Temperature and Humidity Sensor Module1 x Jumper Wire
