Temperature sensor with six meter external probe HOBOnet RXW-TMB-6-868 network
The sensor HOBOnet measures the temperature of the'air ground and of'water, it sends data to a central station via mesh technology wireless.
Economic and evolutionary, it has a measuring range of -40 ° to 100 °C, one high precision of ± 0.2 °C, one wireless reach 450 to 600 metres and one built-in memory to avoid data loss.
Important:
Includes lithium batteries.
A complete system requires hOBO RX station, one wireless manager HOBOnet and one wireless sensor HOBOnet.
Des wireless repeaters HOBOnet can be added to extend the range of both system options.
A solution economic and progressive for the monitoring online temperature of the'air.
Wireless sensors HOBOnet communicate the data directly to a hOBO RX station or transmit data via other wireless sensors at the central station.
They are preconfigured and ready for deployment.
Data are accessible via HOBOlink, the innovative cloud software platform of'Onset.
