SMD LEDs replaced
1, humidity measuring range: 20 --- 90% RH
2, humidity measurement accuracy: 5% RH
3, the temperature measuring range: 0 --- 50 ?
4, the temperature measurement accuracy: 2 ?
5, the working voltage: DC5V / 3.3V
6, the digital signal output
7, data port pull-up resistor
8, with 3mm fixing screw holes for easy installation
V. wiring methods:
VCC 3.3V / 5V positive power supply
GND power supply negative
DATA microcontroller IO port
Tips: Do not VCC and GND reversed, the reverse will burn!
