Device construction
Power supply
The sensors are intended to be powered with 5V DC directly from Daxi, IQIO, Hero modules.
Dimensions
Enclosure
The mounting openings in the device enclosure allow the sensors to be mounted directly to a wall or in an 19 inch rack cabinet.
The colour green indicates the opening intended for the communication and power wiring.
Blue colour indicates openings used when mounting to a rack cabinet.
The openings marked with red allow the module to be installed on a wall with an expansion anchor. Its position can be adjusted.
Technical characteristics
| WebSensor HT | |
|---|---|
| Temperature sensor | DS18B20 mounted on the PCB Measured temperature range: from -55°C to +125°C (-67°F to +257°F) Precision in the range -10°C and +85°C: ± 0.5°C Precision in the range -55°C to +125°C: ± 2°C |
| Humidity sensor | Humidity sensor mounted on the PCB Measured humidity range: 0÷100% RH Precision: ± 3% |
Connecting sensors
The WebSensor can be connected to a bus using a two- or three-wire (Hero, IQIO) cable with a maximum diameter of 1mm2 or with RJ12 connectors (Daxi).
The sensor uses the 1-Wire bus, that's why additional sensors can be connected to make the bus longer and read the measured values from several sensors (Daxi, IQIO, Hero)
The RJ12 Bus connectors and the three-way screw terminals are connected in parallel.
