Wiring diagram

6.1 Digital temperature and humidity module: Single / multiple DS18B20, RW1820, DS1990 sensor input wiring diagram

SHT1X, SHT7X input wiring diagram
Note:
VDD (Vdd +) and (Vdd-) are the sensor power terminals that can be wired nearby;
1
Pin connection definition of DS18B20, RW1820, DS1990, SHT1X, SHT7X sensors can be seen in respective technical
2
information;
Cables between sensor DS18B20, RW1820, DS1990 and module are recommended to use shielded 4-core twisted pair;
3
one set of cable can be connected to ground (Vdd-) and signal lines (DT), the other set of cable can be connected to power
supply and ground (Vdd-), the shield is single-point grounded at the source.
