Sensor for temperature, humidity and light
DB2-RH-T-LX
 |
Key features
|
DB2-RH-T-LX is a battery powered device which perform temperature, humidity and light measurements at the same time and send them at regular intervals to a Gateway of the Digitron products family.
This device may be confi gured to manage alarm thresholds for exceeding maximum or minimum levels of measures.
It is also possible to adjust the sampling and data transmission rate to improve battery life.
The sensors are protected into a plastic material case such as Gore-Tex in order to let only air entering and no water.
