returns an answer signal. Then the host receives the answer signal and begins to receive 40-

bit humiture data (8-bit humidity integer + 8-bit humidity decimal + 8-bit temperature integer

+ 8-bit temperature decimal + 8-bit checksum). For more information, please refer to DHT11

datasheet.

Experimental Procedures

Step 1: Build the circuit

Humiture Sensor Module SunFounder Uno

S --------------------------------------- D4

- ---------------------------------------- GND

+ --------------------------------------- 5V

LCD1602 connection: connect pin RS to digital pin 5; R/W to GND; E to digital pin 6; D4~D7 to

digital pin 9 to 12; VSS to GND; VDD to 5V; A to 3.3V; K to GND

Potentiometer connection: Connect the middle pin to VO of LCD1602 and any other pin to

GND

Step 2: Program (Please refer to the example code in LEARN -> Get Tutorial on our website)

Step 3: Compile

Step 4: Upload the sketch to SunFounder Uno

Now, you can see the value of the current humidity and temperature displayed on the LCD.
