Humid-1Wire: Relative humidity sensor


Czech version


English vrsion

Digital relative humidity sensor for indoor and outdoor use.
RJ11 (1-Wire) interface. Designed to work with Poseidon, Ares and HWg-STE units.

Communication takes place over the digital bus; each sensor has its own unique serial number. Sensors are designed to work with HW group products.

Sensors can be connected in parallel using T-Box units, or daisy-chained. Some sensors have two RJ-11 connectors and are supplied with a RJ11 connection cable. Total length of bus connected to an active port should not exceed 60m..

Examples of sensor connections

Star topology – up to 60m + T-Box

  • Sensors can be connected in parallel using a T-Box or T-Box2 splitter.
  • Total wiring length should not exceed 60 meters from an active port.
  • Combined temperature+humidity sensor appears as 2 different sensors. Two different IDs.

Daisy chain – 60m maximum total length

  • Some sensors feature a RJ11 connector for daisy-chain (serial) connection.
  • 3m connection cable is usually included.
  • Total wiring length should not exceed 60 meters from an active port.

4 active ports - 4x 60m

  • After autodetection, sensors cannot be moved between individual active ports. When a sensor connection changes, autodetection needs to be re-done.
  • Total wiring length should not exceed 60 meters from an active port.
