Wireless temperature and humidity system

The Saveris radio probes measure temperature and humidity. The probes save their measurement data and send it to the central base at regular intervals. If a limit value is exceeded, a radio link is established immediately. Through bidirectional transmission, the radio probe and the base are in mutual contact, ensuring that the measurement data is only recorded by the base and is not interfered with by other radio systems. An alarm sounds in the event that the radio link is interrupted by obstacles and the memory in the probe ensures that the measurement data is not lost in the event of interference in the radio link.

In free field, the transmission path is approximately 100 m at a frequency of 2.4 GHz. The radio link can be improved or extended in poor environmental conditions by using a router. The radio probes are available with or without a display as an option, which shows current measurement data, the battery status and the quality of the radio link.

In addition to the radio probes, probes can be used that are directly connected to ethernet and use mains power rather than batteries.

The base station can save 40,000 readings per measurement channel, which corresponds to around one year of memory capacity at a measuring rate of 15 mins. An emergency battery ensures that an alarm is transmitted and that no existing data is lost in the event of a power failure. The base issues an alarm by means of an LED if the limit value is exceeded, or optionally via SMS and via a relay output to which an alarm transmitter can be connected. In total, a base can incorporate 150 radio and ethernet probes or 254 measurement channels. The Saveris base can be connected to a PC either via USB or ethernet.
