DATASHEET
The Enistic Light Sensor is a battery powered digital light sensor designed for general office, residential and light industrial use.  As well as reporting the lux levels, the sensor can be used to trigger events within the Energy Manager Online system to allow lights to come on and devices to be controlled when specific levels are reached.
  • Measure the light levels of rooms
  • Control devices if set points are reached
  • BMS integration
  • Data logging & remote data logging
  • Home and office energy management
  • Automated control of other building management devices

Application & Features

  • Readings sent to Energy Manager Online
  • Can be used with the Online portal or the desktop software
  • Using Energy Manager Online, email / SMS alerts can be created
  • When used with iBEMS or mini-iBEMS, can be used to trigger BMS rules when set points are reached (high or low)
  • Encrypted communications for secure operation
  • Mesh networking for excellent range
  • Long battery life (Up to 2 years) in normal operation
  • Simple “stick on” installation
  • Unique serial number embedded in each device for identification on network
