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.

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%.

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

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.
