Echoflex releases WDS9 Wireless Open-Loop Photo Sensor

The new WDS9 from Echoflex Solutions is a wireless, solar-powered, open-loop photo sensor.  The WDS9 is designed for indoor use and does not require batteries or wires to operate, allowing it to be mounted inconspicuously on the window mullion. The WDS9 monitors exterior light levels (up to 65000 lux / 6000 footcandles) and sends out wireless transmissions whenever the reading has changed more than 3%. It can also be set to send a transmission on “heartbeat,” updating the light levels once every minute during daylight hours and every hour during the night. This dynamic setting allows users to choose how they prefer to save energy.

The WDS9 is entirely solar-powered, with maintenance-free energy storage offering reliable, 24-hour operation for the life of the sensor. Configuration of the WDS9 is easy, with a simple button press for daylighting configuration. Because it is wireless, it mounts in any orientation on the window mullion with strong adhesive pads to make sure it stays in place.

Available in white, gray, or black, the WDS9 provides a simple method to control dimming of interior lights based on exterior daylight conditions.

The new WDS9 Wireless Open-Loop Photo Sensor features:

  • Open loop photo sensor that is powered entirely by the sun
  • Stores energy for continuous 24-hour operation
  • Mounts with adhesive pads in any orientation on the window mullion
  • Simple button press process for daylighting configuration
  • Available in white, grey, and black
