LM-1ZW Ambient Light Sensor
Introduction
LM-1ZW is a Z-Wave Ambient Light Sensor. It monitors your home environment and transmits measured Illuminance (lux),
to the coordinator in the Z-Wave network.
The Sensor is a Z-Wave enabled device and is fully compatible with any Z-Wave enabled network.
Z-Wave is a wireless communication protocol that uses a low-power RF radio. By taking advantage of the Z-Wave mesh
network, commands can
be transmitted to their destination via intermediary “listening” Z-Wave products.

Features
Lighting Monitoring
The sensor measures illuminance to transmit measured data to Z-Wave Control Panel/Gateway regularly.
Illuminance reading is transmitted every 1minute.
The sensor will also transmit signal automatically when:
The current illuminance changes by +/- 30%.
The current illuminance changes by +/-500 (lux)
The illuminance detection range is 0~180000(lux)
Battery and Low Battery Detection
The sensor uses one CR123A 3V Lithium battery as its power source.
The sensor features Low Battery Detection function. When the battery voltage is low, the sensor will transmit Low
Battery signal to the Gateway/Control Panel. The Sensor will report its battery percentage to the Gateway/Control
Panel respectively at 100% (voltage 3.2 to 2.85V), 75%(voltage 2.84 to 2.72V), 50%(voltage 2.71 to 2.59V) and
25% (voltage 2.58 to 2.33V). If the battery voltage is low (25%), a Low Battery signal will be sent to the Control
Panel to notify the user.
When changing battery, after removing the old batteries, press the Function Button twice to fully discharge before
inserting new battery.
Wake Up
This function uses the Z-Wave Wake Up Command Class. The Wake Up Command Class allows the battery-powered
Sensor to notify the Control Panel/Gateway that it is awake and ready to receive any queued commands. The wake up
time period is programmed automatically according to Control Panel
’s setting when The Sensor is included. The
recommended setting of the wake up time is 60 minutes above.
