Moisture Sensor


The Urban.io Moisture Sensor reports on the level of moisture, from 0 to 100, detected by it’s probe. It can alert you to potential damage that can result from flooding or leaks; or conversely if a system such as an evaporative cooler goes dry. This sensor resports on the amount of moisture is present by measuring conductivity between the two prongs at the end of it’s probe.


This product is designed for usage with an Urban.io IoT Gateway. In ideal conditions with correct orientation of sensors and gateway antennas the following ranges can be achieved.

  • Up to 5km line-of-sight where there are no obstructions between the gateway and the sensor and they are placed on the same horizontal plane.
  • 500m non-line-of-sight in an enclosed space where there are one or more obstructions (objects, walls, buildings) between the gateway and the sensor and it is placed on the same horizontal plane.

This product is designed for application in normal indoor and certain outdoor environments. The gateway housing is IP65 rated and as such is designed to be water and dust resistant as well as generally resistant to direct sunlight. However the 240v Power Adapter is not rated for outdoor usage.

Urban.io proactively supports the interfacing of IoT sensor data with all industry leading Asset Management, Field Force and Work Management, Data Analytics and Machine Learning Platforms. We provide the following Public APIs as well as pre-built API Adapters for the following Enterprise IoT Systems :

  • API publics : MQTT, Rest Web Services
  • API adaptés : AWS IoT Core, IBM Watson IoT, Azure IoT Hu​b
