LMHT-1ZBS    Ambient Light, Humidity and Temperature Sensor 
 
 
Introduction 
LMHT-1ZBS is a ZigBee Ambient Light, Humidity and Temperature Sensor. It monitors your home environment and 
transmits measured Illuminance (lux), humidity and temperature to the coordinator in the ZigBee network. 
The sensor utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless communication protocol that is 
reliable, has low power consumption and high transmission efficiency. Based on the IEEE802.15.4 standard, ZigBee allows 
a large amount of devices to be included in a network and coordinated for data exchange and signal transmission. 
The sensor serves as an end device in the ZigBee network. It can be included in the ZigBee network to transmit signal 
upon activation, but cannot permit any other ZigBee device to join the network through the sensor.   
 
Parts Identification 
1.  Light Sensor / LED Indicator 
Flashes once: Factory Reset 
Flashes twice: After the sensor has successfully joined a ZigBee 
network. 
Flashes 3 times: Battery inserted. 
Flashes 5 times: Low battery detected when inserting battery. 
Flashes once every 20 minutes: The sensor has lost connection to 
its current ZigBee network. 
2. Temperature Sensor 
3. Battery Compartment 
4. Function Button 
Press once to send a signal to the coordinator. 
Press and hold for 10 seconds to reset the device. 
 
Features 
  Lighting, Humidity and Temperature Monitoring
 
 
The sensor measures illuminance, humidity and temperature to transmit measured data to ZigBee network 
coordinator regularly.   
Illuminance reading is transmitted every 30 minutes. 
Humidity and temperature reading is transmitted every 10 minutes. 
The sensor will also transmit signal automatically when: 
  The temperature changes by +/- 2°C.  
  Humidity changes +/- 10%. 
  When the current illuminance changes by +/- 10%. 
 
You can also press the Function Button once to transmit current reading manually. 
  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 coordinator in ZigBee network 
 
When changing battery, after removing the old batteries, press the Function Button twice to fully discharge before 
inserting new battery. 
 
If low battery voltage is detected upon inserting new battery, the LED indicator will flash 5 times. 
  Supervision 
The sensor will transmit a supervision signal along with the reading signal to report its condition regularly. The factory 
default interval is 30 minutes, which can be adjusted according to setting.
