Product Information

Product Description

Authorized North America Distributor Stamp

Connect up to 4 AKCP intelligent sensors to the sensorProbeWT  Wireless Tunnel™ (SP-WT) and communicate these sensors over long distance with LoRa™ based wireless communications. AKCP’s proprietary Wireless Tunnel™ protocol provides guaranteed message delivery without loss of data and low power utilization for superior battery life.

Use the sensorProbeWT to connect up to 4 wired sensors to a single radio for rapid deployment of a large number of sensors. Connect up to 30 devices to the sensorProbe Wireless Tunnel™ Server. With 4 sensors on each unit, a total of 120 sensors can connect to the server with only 30 radios.

Build your own private LoRa based network without the need for any cloud services. Data is transmitted to the sensorProbe Wireless Tunnel Server (SP-WTS). Multiple servers can be monitored centrally with AKCPro Server. This server can run locally or on a cloud service. 

The SP-WT is powered by either 3 AAA batteries, or 5VDC USB input. Both can be used with the batteries as a failover power source. It is recommended where possible to power the sensorProbeWT via external power supply.
