Data monitoring system transmitter

BHS Data Gateway BTCPLRX2

The data gateway is the central element of a remote monitoring system. It receives readings from wireless temperature, humidity and probe sensors over a radio channel and forwards them to the cloud monitoring platform through a standard RJ-45 Ethernet connection.

One gateway serves up to 250 wireless sensors, making it suitable both for small sites with a few measuring points and for large warehouses, production facilities and retail chains. Data exchange between the sensors and the gateway is encrypted with AES-128.

If the internet connection is temporarily lost, the gateway stores readings in local non-volatile buffer memory and uploads them to the server automatically once the connection is restored. This prevents gaps in the measurement history, which matters for HACCP and audit requirements.

Key benefits

• Up to 250 wireless sensors per gateway
• Local network connection through a standard RJ-45 Ethernet port
• 868 MHz wireless communication, range up to 150 m in clear line-of-sight conditions
• Repeater mode for extending coverage in large facilities
• AES-128 data encryption on the wireless channel
• Local buffer memory for temporary internet outages
• External 5 V power supply — continuous operation without batteries
• DHCP mode by default — fast connection without network configuration

Compatible sensors

• MCP9808 wireless temperature sensor
• ENS210 wireless temperature and relative humidity sensor
• DS18B20 wireless temperature sensor with external probe
• PT100 wireless temperature sensor with external probe
• PT100 High Accuracy wireless high-precision temperature sensor

Applications

• Commercial refrigeration — shops, display cabinets, cold and freezer rooms
• Warehouses and logistics centres — temperature and humidity data across the whole area
• HVAC systems and technical rooms
• Laboratories and medical facilities
• Server rooms and data centres
• Museums and archives — microclimate monitoring
• Industrial sites with centralised data collection

Installation and configuration

The gateway is connected to an active network switch or router with an RJ-45 cable and powered from a 5 V adapter or micro-USB. DHCP mode is enabled by default, so the device receives its network settings automatically. For projects requiring a static IP address or custom network settings, configuration can be performed from a PC using the USB configuration utility.

The enclosure is mounted with industrial double-sided adhesive tape on a smooth surface. Repeater mode settings are stored in non-volatile memory and remain active after power cycling.

Technical details

The gateway is not a sensor itself — it collects data from wireless sensors. BHS specialists carry out system installation, network and gateway configuration, sensor programming, limit and alarm setup, and staff training.
