Four, features:

1, humidity measuring range: 20 --- 90% RH

2, humidity measurement accuracy: ± 5% RH

3, the temperature measuring range: 0 --- 50 ‘C

4, the temperature measurement accuracy: ± 2 ‘C

5, the working voltage: DC5V / 3.3V

6, the digital signal output

7, data port pull-up resistor

8, with a fixed screw hole, diameter 2.6mm

V. wiring methods:

VCC → 3.3V / 5V power supply positive

GND → negative power supply

DATA → microcontroller IO port

Tips: Do not reverse VCC and GND, reverse will burn!
