Combined temperature and humidity sensor for vertical wall mounting indoor usage. Communication over RS-485 bus with a simple communication protocol. The sensor can be used separately but it was designed to be connected with the Poseidon family units.

HTemp-485 Box2 measures temperature and humidity, communicates over 4-wire bus and up to 26 sensors can be connected parallely to a single bus. The sensor is intended for indoor vertical wall mounting.

The busbar uses 4 wires, two with a standard RS-485 line, the other two are used for sensors' power supply. The individual sensors can be powered by an external power source and can be connected by just two RS-485 line wires. RS-485 communication line works up to 1000m distance.

For temperature measuring the thermal sensor uses an integrated element with accuracy of ±0.5°C, humidity is as well measured by an internal sensor with accuracy ±4%.

Applications:

Extensive measuring systems with many measuring points
Air-conditioning state measuring and measuring of living conditions in intelligent buildings
Independent measuring in food warehouses and agricultural crops storage buildings
Grocery storehouses and premises
Temperature and humidity monitoring in pharmaceutical storages
Measuring in residential premises
Industrial measuring and regulation
After connection to the Poseidon model 1250 or 2251 – temperature values transmission over Ethernet or Internet
After connection to the Poseidon model 2251 – logging possibility of up to 100 000 values into internal Flash memory
