Ambient Light, Humidity and Temperature 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 c/- 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.
ZigBee Network Setup
ZigBee Device Guideline
ZigBee is a wireless communication protocol that is reliable and 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.
Due to the fundamental structure of ZigBee network, ZigBee device will actively seek and join network after powering on. Since performing a
task in connecting network may consume some power, it is required to follow the instructions to avoid draining battery of a ZigBee device
- Ensure your ZigBee network router or coordinator is powered on before inserting battery into the ZigBee device.
- Ensure the ZigBee network router or coordinator is powered on and within range while a ZigBee device is in use.
- Do not remove a ZigBee device from the ZigBee network router or coordinator without removing the battery from a ZigBee device.
