Light Sensor
The Urban.io IoT Light Sensor detects and reports the intensity of light in lux
within indoor environments.
This sensor uses a photoresistor to detect the intensity of light around the device.
The sensor returns a value between 10 and 1000 lux making it suitable for
detection of light levels within indoor environments.
NOTE : this sensor is not suitable for outdoor light level measurement beyond
1000 lux.
his 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 :
